It is found\, that the main com bustion product is aluminum nitride. In the combustion of aluminum nanopow der\, aluminum γ-oxide is the first to form\, and aluminum nitride is for med next. The formation of aluminum probably occurs by successive displace ment of oxygen by nitrogen from the aluminum oxide. The use of sliding (in cident at a small angle to the surface) synchrotron radiation made it poss ible to determine with high accuracy (in time) the sequence of stages of f ormation of crystalline products during combustion of the aluminum nanopow der.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1238/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1238/ END:VEVENT BEGIN:VEVENT SUMMARY:Source-Based Calibration of the Soft X-ray Detectors at the SSTRC DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1153@indico.inp.nsk.su DESCRIPTION:Speakers: Anton Nikolenko (BINP)\, Natalya Makarova (Altai Sta te Technical University)\nThe development of the procedure of absolute cal ibration of the soft X-ray detectors is presented.

As rule\, Busofit and CNF based catalysts have improved catalytic selectivity\, activity and thermostability as com pared to the traditional carbon supported catalysts using carbon-black or Sibunit as supports. This modification of catalytic properties is believed to result from higher accessibility of the deposited active component to the reactants and from strong interactions between the catalyst particles and the support surface. This work is devoted to the comparative structura l study of few promising Pt\, Pt-Me carbon-based \ncatalytic systems using different carbon supports by the EXAFS methods: 1) Pt\, Pt-Me Busofit-bas ed catalysts for CO oxidation\; 2) Pt\, Pt-Me CNF-based cathode catalysts for PEMFC\; 3) Pt\, Pt-Me Sibunit-based catalysts for hydrocarbon conversi on. Mesoporous granular carbon composite - Sibunit and carbon active fibe rs " Busofit (as woven activated carbon fabric modified with thermally sta ble acid groups) was used for prepaation of supported metal catalysts. Pl atinum in Pt- and PtMe-forms of Busofit was introduced from Pt(NH3)4Cl2 aq ueous solution by means of impregnation and ion-exchange. A series of CNF with different arrangement of graphitic planes were synthesized by decomp osition of methane and ethylene over transition metal catalysts. These str uctural types of CNF were used for preparation of the Pt\, Pt-Me catalysts for PEMFC cathodes. Various synthetic techniques were studied\, using H2P tCl6 and other Pt complexes as Pt precursors. All EXAFS spectra of the stu died samples were recorded at Siberian Synchrotron and Terahertz Radiation Center (SSTRC\, Novosibirsk). The local Pt and Me (Fe\, Cu\, Co) arrangem ents of all the samples studied were established and the phase composition s were determined. It was shown that there are some differences of the met al arrangements for the studied systems. All possible structural models we re discussed. In addition\, these samples were studied by the TEM\, EDX an d X-ray diffraction methods. The data of all methods are in a good agreeme nt. \n\nThe work was done using the infrastructure of the Shared-Use Cente r “Siberian Synchrotron and Terahertz Radiation Center (SSTRC)” based on VEPP-3 of BINP SB RAS.

DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1157@indico.inp.nsk.su DESCRIPTION:Speakers: Victor Shapovalov (Southern Federal University)\nTra nsitional metals fluorides have been known from 1960s in the field of rech argeable batteries. They belongs to the conversion materials\, and by reac tion with lithium can be reduced to the mixture of zero valent metal and l ithium fluoride\, resulting the so-called more-than-one electron reaction. However\, possibly due to the lack of nanostructuration of commercial com pounds\, fluorides gave the way for more immediately interesting and promi sing materials.\n\n\n----------\n\n\nSince 1960s various technologies for producing of nanocompounds have been developed\, so fluorides became one o f the leading research directions for Li-ion industry. Most efforts are be ing put into iron trifluoride for several reasons: it’s more environment ally friendly than others\, cheaper\, requires reasonable synthesis condit ions\, has relatively low polarization\, etc.\n\n\n----------\n\n\nIn our study we pursue the goal to determine structural changes which take place inside the full cell and to look at those processes in situ during cycle. Experiment was carried on the B station of BM01 (SNBL) beamline at ESRF\, Grenoble\, as a mixed XAFS/XRD experiment. Samples were prepared with synt hesis of iron fluoride nanoparticles inside reduced graphene oxide sheets which increases conductivity. The material offers a stable discharge energ y of 600-700 Wh/kg over 100 cycles\, which is higher than the widely appli ed cathode materials (300-500 Wh/kg). Each sample we cycled with 20 mAh/g in the 1\,2-4\,2 V range\, while measuring Fe K-edge XAFS spectra in trans mission mode and XRD patterns with 15 minutes interval. For measurements w e used self-made test cells with glassy carbon windows connected to Gamry potentiostats responsible for cycling and data acquisition.\n\n----------\ n\nThe Li intercalation in the first discharge is different from subsequen t cycles. Up to 1.8 V\, a maximum of 0.66 Li will be inserted into the cha nnels of the framework structure of initial FeF3  0.33H2O (from synthes is conditions). Then peaks in the XRD patterns disappear and nanocrystalli ne LiF and Fe phases will form below 1.8 V. On charge\, the ReO3-type FeF3 phase with higher density will form instead of the open-framework structu re. On second and subsequent discharge reactions\, we will form LiFe2F6 in stead\, which then also converts to LiF/Fe. This is of theoretical nature\ , because of the nanocrystalline structure of the involved phases\, which is too small to detect in XRD\, and also similar Fe-F6 environments\, whic h make the FeF3 phases very hard to distinguish in XAS.\n\n\n----------\n\ nResults of the x-ray studies were associated with cycling data to obtain structure-charge state dependency. HTB structure of the as-prepared materi al has open intercalation channels as a result\, full electrochemical reac tion can be separated into initial intercalation of one Li- anion per form ula unit and following conversion reaction involving two more Li-\, which gives us 3LiF/Fe mixture and a complete three electron transition. To prov e this we performed principal component analysis (PCA) on the series of XA FS experimental spectra. We have used FitIt software to mathematically dec ompose the series of the Fe K-edge spectra at different voltages into inde pendent sub-spectra. It was found that all spectra for discharge process c an be reproduced as a combination of three components. First component cor responds to HTB structure\, second to the intercalated structure with Fe2+ charge state and the third one corresponds to metallic Fe. We have observ ed that pure Fe forms after HTB conversion to intercalated phase. \nWe als o performed a set of ab initio calculations and DFT modeling for different concentrations of Li in cathode material. Theoretical simulations for the Fe K-edge XANES are in progress now to figure out if we can distinguish i ntercalated HTB structure from the LiFe2F6 phase in the XANES data.\n\nhtt ps://indico.inp.nsk.su/event/3/contributions/1157/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1157/ END:VEVENT BEGIN:VEVENT SUMMARY:THE CRL'S OPTICAL PROPERTIES OF BERYLLIUM GRADES IS-50M AND O-30- H DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1158@indico.inp.nsk.su DESCRIPTION:Speakers: Ivan Lyatun (X-Ray Coherent Optics Laboratory (IKBFU ))\nX-ray refractive lenses [1-3] are widely used as beam transport and b eam conditioning optics at the new generation synchrotron radiation source s. In order to extend their use for microscopy applications the signifi cant improvements of the optical properties in terms of shape quality a nd bulk homogeneity are needed. It turned out that beryllium\, as a low -Z element\, is the most suitable for lens manufacturing. However\, beryll ium being a sintered material has an internal grain structure with a rel atively high content of the beryllium oxide\, which create a strong small- and ultra-small angular scattering.\n In this work we report results of study of different types of beryllium (Materion Brush and Russian ROSA TOM grades) using small angle scattering and phase contrast imaging techni ques. It was shown that Be with a reduced oxygen content is preferable for microbeam applications. As for the full-field microscopy\, Be with small grain sizes is required. In this view a so-called “nano-beyllium” with grain sizes smaller than 50 nm is very promising for lens manufactuiring. \n\nReferences\n\n 1. Snigirev\,A.\,Kohn\,V.\,Snigireva\,I. & Lengeler B.

Possibility to produce micelles based on amphiphilic bloc k-copolymers with a defined morphology makes them attractive for applicati ons as drug delivery systems. \n\nThe objects of this study were non-toxic \, biocompatible\, biodegradable amphiphilic diblock (PLLAx-b-PEOy) and tr iblock (PLLAx/2-b-PEOy-PLLAx/2) copolymers with various hydrophobic/hydrop hilic blocks lengths ratio. The aim of this study was to investigate influ ence of a composition of the initial block copolymers on the construction and properties of the micellar structures by small-angle x-ray scattering (SAXS). The research work was performed using synchrotron radiation at the P12 beamline at the Petra III storage ring (DESY\, Hamburg).\n\nWe have r evealed that the investigated block copolymers in water solution formed co mplicated two-level systems consisting of individual micelles and ordered supramicellar structures\, properties and parameters of which strongly dep end on the architecture and composition of the initial block copolymers. I n particular\, considerable increasing of the length of the hydrophobic la ctide block PLLA from 64 up to 418 units (the length of the hydrophilic bl ock poly(ethylene oxide) was a constant) in the diblock copolymers resulte d in a paradoxical decreasing of the periodicity of the ordered motifs\, t hat can be explained by a formation of a folded structure of the long PLLA block. Increasing of the length of the hydrophobic lactide block PLLA fro m 30 up to 120 units in the triblock copolymers didn’t lead to a change of the system spacing. All block copolymers demonstrated a high degree of the polydispersity. For the investigated block copolymers based on PLLA an d PEO micelles the main relatively narrow fraction was presented by micell es with diameter of about 20 nm\, but there were also larger scattering ob jects with the sizes up to 150 nm in the solution. \n\nAs a result\, on th e base of SAXS data\, dynamic light scattering\, atomic force and cryo-tra nsmission microscopy data a theoretical model of the system was suggested. \n\nThis work was supported in part by Russian Foundation for Basic Resea rches\, project 16-03-00375.\n\nhttps://indico.inp.nsk.su/event/3/contribu tions/1201/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1201/ END:VEVENT BEGIN:VEVENT SUMMARY:OBSERVATION OF GRAIN-BOUNDARY STRUCTURE FEATURES IN ALUMINIUM ALLO YS BY MEANS OF XAS AND X-RAY TOMOGRAPHY BY SR DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1161@indico.inp.nsk.su DESCRIPTION:Speakers: Alexander Nizovskii (Boreskov Institute of Catalysis )\nAluminum and its alloys are considered to be the promising agents for h ydrogen production in reaction with water to use them in compact fuel cell s. The only problem is to increase their reactivity. One of the methods of activation is the treatment of aluminum by gallium-based liquid metal eut ectics. Previously\, we noted that the process of activating the aluminum alloys was associated with the grain boundary diffusion of the eutectic co mponents.\nTo determine the nature of high reactivity of the activated mat erial in reaction with water\, a number of commercial aluminum alloys were studied with the help of the methods of XAS and X-Ray tomography by SR af ter activation. It was shown that the highly active state was associated w ith the formation of the nanostructured material\, wherein the components of Ga-In eutectic distributed throughout the grain boundaries in the all t he mass of the original sample.\nTo confirm this observation\, the aluminu m alloys with different grain boundary structures have been investigated i ncluding those having high reactivity as well as the samples which lost th e activity during prolonged storage under atmospheric conditions. Using X- ray tomography by SR\, it was shown that in all the highly reactive sample s\, the components of Ga-In eutectic were distributed in the grain boundar ies of the entire material. The activated samples\, in which the component s were not evenly distributed\, did not completely dissolve in water. By X AS method\, it has been found that in the highly active material\, the eut ectic components were in metallic state. Deactivation during prolonged sto rage under atmospheric conditions was associated with oxidation of the com ponents of the eutectic alloy.\nIt is shown that the distribution of the eutectic component in the sample is determined by the grain boundary struc ture of the initial material.\n\nhttps://indico.inp.nsk.su/event/3/contri butions/1161/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1161/ END:VEVENT BEGIN:VEVENT SUMMARY:Vibrating wire magnetic field measuring technique DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1163@indico.inp.nsk.su DESCRIPTION:Speakers: Artem Zorin (BINP)\nVibrating wire magnetic field me asuring technique is a kind of current driven wire based magnetic measurem ent system.

Mosc ow State University\, Moscow\, 119992 Russia)\nDihydrolipoamide dehydrogen ase from Escherichia coli (LpD) is a bacterial enzyme that is involved in three different multi-enzyme complexes that catalyze similar decarboxylati on reactions of 2-oxoacids. All of these complexes comprise three enzymes known as Е1\, Е2\, and Е3\, where LpD is the Е3 component and the E2 s ubunit is used by LpD as the lipoamide-containing protein substrate. The Е1 and Е2 subunits have different structures in different complexes\, wh ereas the Е3 protein is essentially the same in all of the complexes [1 –4]. The pyruvate dehydrogenase complex from Gram-negative bacteria (for example\, from E. coli) is composed of 24 E1 subunits and 24 E2 subunits\ , whereas the multiplicity of E3 remains unknown. According to different e stimates\, there are 12 or 24 E3 subunits\; i.e.\, E3 may consist of six d imers or six tetramers. It was shown that E. coli LpD exists as a dimer i n the crystalline state [5]. However\, the solution structure of this prot ein was unknown. The aim of the present study is to investigate the behavi or of LpD in solution\, i.e.\, under near-physiological conditions\, by sm all-angle X-ray scattering (SAXS) and complementary methods. Using modern techniques for the interpretation of SAXS data and analytical ultracentrif ugation we determined that in solution LpD exists as an equilibrium mixtur e of a dimer and a tetramer. The tetramer structure was determined by mod eling SAXS data and molecular docking. The results obtained by these two m ethods correlate well with each other. It was shown that there is the rela tionship between the oligomerization of the protein in solution and its fu nctional properties. In particular\, the possible flexibility of the tetra mer follows from the stoichiometric and functional demands of the multienz yme complexes containing LpD as a component.\n\nThis work was supported in part by Russian Foundation for Basic Researches (projects 15-54-74002 EMB L_а \, 15-04-01406\, 15-04-00563).\n\nReferences\n[1] R.

Among the variety of dendrimers\, carbosilane dendrimeric macromolecules attracted great attention for their reactive functional gr oups\, chemical inertness of the molecular skeleton and possibility of med ical and biological applications [1\, 2]. \nIn the present work three-dime nsional structure of monodisperse carbosilane dendrimers of zero\, third a nd sixth generations were studied by small-angle X-ray scattering (SAXS) i n hexane solution. Using modern methods of SAXS data interpretation\, incl uding procedure of ab initio modeling\, spherical shape and internal archi tecture of the dendrimers were revealed depending on the generation number and on the number of cyclosiloxane end groups constituting a shell of the macromolecules. With the help of a computer simulation a possibility of s hape reconstruction of the dendrimer molecules in clusters has been consid ered\, and the analysis of the intermolecular interaction of the dendrimer s in solution was performed applying the latest developments of the method of molecular tectonics.\n\nThis work was supported in part by Russian Fou ndation for Basic Researches (projects 16-03-00379 and 16-03-00375)\nRefer ences\n[1] Dendrimers and other dendritic polymers / Ed. by J.M.

SAXS experiments were carried out using synchrotron r adiation at the P12 beamline at the Petra III storage ring (DESY\, Hamburg ). Modern techniques for interpretation of scattering data and structural modeling\, including ab initio protocol\, have been applied in the present work [1]. Obtained values of radii of gyration (Rg =8.9 ± 0.1 nm for PVA CP at pH 7.8 and Rg=8.5 ± 0.1 nm for this protein at pH10.5) are too lar ge to be a characteristic of the isolated protein macromolecule with molec ular mass of 30.26 kDa calculated from the amino acid sequence of PVA CP. The average molecular masses (MMs) of the solutes were obtained by us (i) from the extrapolated I(0) and (ii) from the excluded (Porod) volumes Vp of the species. MMs calculated by these 2 independent methods clearly ind icate formation of large aggregates containing dozens (30-60) of individua l PVA CP macromolecules. Thus\, the overall parameters (Rg\, excluded Poro d volume\, MMs) point to the existence in the solution of large particles consisting of many protein macromolecules. On the other hand\, Porod plots as well as Kratky plots revealed rather compact particles with definite s hapes though less expressed for PVA CP at higher pH. It means that possibl y we observed not aggregates\, which as a rule do not possess a certain sh ape\, but we can see a formation of some kind of ordered structures\, most possible short virus-like particles (VLPs). The structure and overall cha racteristics of the VLPs depend strongly on such solution condition as pH: while a scattering curve from the sample at pH 7.8 demonstrates intensity pattern characteristic for a specific compact scattering object\, SAXS cu rve from PVA CP changes dramatically at pH 10.5 and corresponds to a partl y disordered body without clearly defined boundaries: the CP associates at pH 7.8 are more compact then those at pH 10.8. The shape of PVA CP at low er pH obtained by ab initio method is closed to a cylinder\, thereby repro ducing the shape of the virus\, i.e. this self-assembling in solution to s hort VLP is an intrinsic biological property of the PVA CP allowing it to create an envelope to protect genetic material of the virus. Increasing pH leads to a partial distortion of this virus-like ensemble: the whole shap e of the PVA CP associates at pH 10.5 becomes loose and splits into separa te spherical parts. Thus\, according to McDonald and Bancroft [2\, 3]\, PV Y CP at pH 10.5 disintegrates into monomers\, destroying the structure of the VLP and pointing to the way of the virus deactivation.\nThis work was supported in part by Russian Foundation for Basic Researches (projects 15- 54-74002 EMBL\, 15-04-01406\, 16-03-00375 and 16-04-00563).\nReferences\n[ 1] Blanchet\, C.E. and Svergun\, D.I.

Computer modelling and comparative analy sing 3D structures of the matrix proteins was carried out for three taxono mically different enveloped viruses with raft-type membranes\, IFV\, Newca stle disease virus (NDV)\, and Human immunodeficiency virus (HIV)\, to dis close amphipathic CRAC containing 3D configurations in their structures\, and to identify putative motifs\, which may be specifically involved in th eir interactions with raft membranes. Common structural feature of all thr ee proteins was found to be the amphipathic structure of their CRAC motifs \, and localization of the outer CRAC regions on the opposite sides of the ir globules. Notably\, in contrast to IFV M1\, one CRAC motif on NDV M app eared on the amphipathic beta-sheet structure. To verify our approach we also comparatively tested the M protein structure of the non-raft vesicula r stomatitis virus: the disclosed surface CRAC motif appeared no amphipath ic configuration. Small-angle X-ray structural analysis (SAXS) of IFV and NDV matrix proteins in solution gave further evidence in support of our co nclusions. M1 protein exists in solution as a monomer with a compact NM-fr agment and an extended and partially flexible C-terminal domain. SAXS anal ysis demonstrates that CRAC motifs of the M1 protein are located on the op posite sides of the NM-fragment perpendicular to the C-domain. NDV M prote in dimerizes in solution\, and its surface CRAC motifs have anti-parallel location on the opposite sides of the dimer. Thus\, such localization of C RAC motifs of two different proteins with two different organizations in s olution allows these matrix proteins to interact both with the membrane an d with the internal components of the virus. Moreover\, our results sugges t that oppositely situated CRAC motifs in pairs of both monomeric IFV M1 a nd dimeric NDV M in the virions may serve as anchors between two neighbour ing raft platforms consolidating and fastening the envelopes of the viruse s. CRAC motifs on the surface of these proteins may be involved in arrangi ng their regular oligomeric structures both in the virions and in solution .\nThis work was supported in part by Russian Foundation for Basic Researc hes (projects 15-54-74002 EMBL and 16-04-00563)\nReferences\n1.

Matrix pr otein M1 in the virus particles is one of the most important and abundant proteins broadly involved in essential processes of the viral life cycle. It makes the structural investigation of the M1 protein particularly impo rtant. We employed synchrotron small-angle X-ray scattering (SAXS) and ato mic force microscopy (AFM) to study the structure of M1 at different condi tions. The low-resolution structural models built from the SAXS data revea l a structurally anisotropic M1 molecule consisting of a compact NM-fragme nt and an extended and partially flexible C-terminal domain [1]. We demons trated also that even at low pH the M1 monomers co-exist in solution with a small fraction of large clusters possessing a layered architecture simil ar to that observed in the authentic influenza virions. AFM analysis on a lipid-like negatively charged surface reveals that M1 forms ordered stripe s correlating well with the clusters observed by SAXS [1]. Low pH conditio n occurs at the very beginning of cell infection leading to an acid-trigge red fusion of the viral membrane. Moreover\, change of pH was found to ser ve as a impuls allowing M1 to carry out its multiple functions in the unco ating\, nuclear transport\, and assembly of the viral ribonucleocapsid [2] . Revealed by us helix-like shapes could be treated as pre-matrix protein superstructures\, whose formation is an intrinsic biological property of t he M1 protein. It can be assumed\, however\, that the oligomerization of M 1 should strongly depend on pH and on the protein charge. That is why it w as important to analyse the structure and self-assembly of M1 at gradually changing pH (up to the neutral pH condition) in solution and on the bare mica surface using SAXS and AFM\, correspondingly. We found that the oligo merization processes occur in a similar way in the solution and on the sub strate\, and quantitatively described these processes. Moreover\, pH 6.0 w as found to be the condition at which binding between M1 molecules starts to break. Our results provide new insights into the mechanism of M1 to for m matrix and virus-like particles alone without partners and give a basis for a further analysis of the hierarchy of M1 in the virus life cycle.\n\n This work was supported in part by Russian Foundation for Basic Researches (projects 15-54-74002 EMBL and 16-04-00563) \n\nReferences\n1.

Development of compound refractive lenses (CRL)\, pro posed twenty years ago [1]\, should be considered as one of the promising solution to this problem. Despite the successful development of refractive optics for X-ray nano-focusing [2] and high-resolution X-ray microscopy [ 3] the diffraction resolution limit for CRL has not been achieved. As alre ady noted [4]\, imaging properties of the CRL depend on the refractive pro perties of the used materials\, and on the accuracy of the manufacturing t echnique of the lens optical surface (figure errors). To improve the surfa ce quality\, dedicated metrological methods to measure geometric character istics of the CRL parabolic profile are required.\n\nIn this work aluminum and beryllium refractive lenses with a parabolic profile (small radii of curvature R = 50 ÷ 1000 μm) made by pressing technique was examined. A c omparison of different metrological methods to study lenses profile is pre sented. Proposed comprehensive laboratory metrological approaches allow to control the quality of the lens profile and to make the input quality con trol of press tools.\n\n\n1. A. Snigirev\, V. Kohn\, I.

The period of identity at spacing of 4.65 (± 0.15) nm is attributed by us to regular attachment of olygosaccha ride chains to the protein core of giant proteoglycan molecules [A.A.Vazin a et al.\, NIM\, 2005\, A543\, 297-301]. A correlation between the integra ted intensity of X-ray patterns and elemental content of tissue is observe d. It is experimentally shown that the structure of proteoglycans can be r eversibly transformed by metal cations and chelating agents\, and that cal cium is the major element in the mineral composition of tissue.\nIn cancer transformed tissues intensity of diffuse scattering and diffraction rings of 4.5 nm varies in a wide range and correlates with change of calcium co ntent in the diseased tissues\, a significant change in elemental content is detected\, up to 200 times increase in the concentration of calcium is found. The final stage of disease is characterized by a significant increa se in small-angle diffuse scattering\; Debye rings are never registered. T reating the tissue with chelating agents such as EGTA and EDTA\, in this c ase turns out to be ineffective\, suggesting the irreversibility of the st ructural transformation of the extracellular matrix.\nThus\, the problem o f cancerogenesis should be looked at in two aspects: investigation of the mechanisms of normal cell transformation which is initiated by DNA damage (mutations)\, and the stages of tumor progression\, processes of malignant cell proliferation\, invasion and metastasis which lead to numerous malig nant tumors. X-ray study of tissues indicates that it may be possible to u se diffraction characteristics of proteoglycan structures as novel markers of pathological transformation of tissues.\nThe research was supported by RFBR-Moscow region Grant #14-44-03667.\n\nhttps://indico.inp.nsk.su/event /3/contributions/1184/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1184/ END:VEVENT BEGIN:VEVENT SUMMARY:The X-FEL quadrupole with gradient 100 T/m DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1185@indico.inp.nsk.su DESCRIPTION:Speakers: Ivan Okunev (BINP)\nAbstract - The paper describes X -FEL quadrupole with gradient 100 T/m.

Many factors have effect on the development of cardiovas cular diseases. The primary reasons of myocardial infarction and stroke ar e hypertension and sclerosis that lead\, with time\, to calcification and contraction of arteries which prevents blood to enter heart and brain. In heart vessels an atherosclerotic plaque forms which closing a vascular lum en\, causes IDH\, and myocardial infarction. Therefore\, studying the deep mechanisms of plaque formation is the focus of attention. The atheroscler otic processes in heart vessels may be explained by several theories that account for the complex processes of atherogenesis. Many papers are devote d to the cellular composition of plaques. Little\, however\, is known abou t the element composition of the atherosclerotic nidus of coronary vessels . Elucidating the content and ratio of chemical elements upon plaque forma tion in heart vessels may substantially supplement the missing stages of t his process.\nThe goal of this study is to determine and estimate a comple x of chemical elements in the substrates of the atherosclerotic nidus of h uman heart vessels.\nThe method of X-ray fluorescence analysis with synchr otron radiation (SRXRF) (VEPP-3\, store ring) was used in Center "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" to study the content of chemical elements in vascular walls and in atherosclerotic plaques (sta ble and unstable) drawn from men after operative therapy. As the amount of material for studying is limited\, we have developed a special technique for preparing the samples of vascular and plaque tissues.\nWe measured the concentrations of K\, Ca\, Cr\, Mn\, Fe\, Co\, Ni\, Cu\, Zn\, Br\, Sr\, Z r\, and Pb. A comparison was made of the content of elements in the tissue s of heart vessels with atherosclerotic plaques and of the element composi tions of stable and unstable plaques. In all the samples studied\, prevail ing is Ca\, particularly in instable plaques. The concentrations of K\, Ca \, Cr\, Mn\,Fe\, Ni\, Zn and Br in atherosclerotic plaques are much higher than in the vascular tissues of heart. At the background of predominant C a no reliable difference has been revealed in the elements measured in sta ble and unstable plaques. A high association of Ca with Fe\, Zn\, and Sr h as been recorded in the atherosclerotic plaques.\nThus\, the SRXRF method has first allowed one to determine the multielement composition in the sub strates of the atherosclerotic nidus of human heart vessels.\n\nhttps://in dico.inp.nsk.su/event/3/contributions/1188/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1188/ END:VEVENT BEGIN:VEVENT SUMMARY:X-ray diffraction data for the study of the multilevel nanostructu res in Ni3Fe deformed single crystals DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1190@indico.inp.nsk.su DESCRIPTION:Speakers: Svetlana Starenchenko (Tomsk State University of Arc hitecture and Building)\nX-ray analysis has been applied for the study of the formation of nanostructures as the result of large plastic deformation in Ni3Fe single crystals ordered alloy with the L12 structure.\nIt was sh own that the main structural changes in ordered alloys had the features si milar to pure metals and the disordered solid solutions. However\, in the ordered Ni3Fe single crystals the formed nanostructure was more complex. S tructure consists of nano-crystallites divided by the antiphase boundaries forming the elements having size a ten times smaller than the dimensions of the crystallites. The antiphase domain structure was not homogeneous. A fter the strain of 0.18 together with the domains\, the average size of wh ich is equal to the original 14 nm\, there were revealed a small fraction of domains with an average size of 10-11 nm. After the strain of 0.38 or m ore\, the average size of the antiphase domains was reduced to 5-2 nm. How ever\, in the material\, a small amount of antiphase domains whose size wa s close to the original (13 nm) also was revealed along with the small dom ains. This indicates that the deformation was carried out inhomogeneously and there remained the sites of material almost unaffected by deformation processes. Analysis of the research points to the emergence of multilevel nanostructure with a clearly expressed of the two scale levels. *The repor ted study was partially funded by RFBR according to the research project № 16-03-00182-а*\n\nhttps://indico.inp.nsk.su/event/3/contributions/119 0/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1190/ END:VEVENT BEGIN:VEVENT SUMMARY:Superconducting solenoid for superfast THz spectroscopy DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1191@indico.inp.nsk.su DESCRIPTION:Speakers: Alexey Bragin (Budker Institute of Nuclear Physics)\ nThis project is related to new spectroscopy method in little-developed TH z \nrange.

Both homodimers and hete rodimers are commonly involved in catalysis\, regulation and structural as sembly. However\, the role of dimerization in controling the action of amp hitropic peripheral proteins that can exist in water-soluble and lipid-bil ayer-bound states is not well studied. Human Glycolipid Transfer Protein ( GLTP) carries out the important function of non-vesicular transport of gly cosphingolipids (GSLs) between membranes [1] but details of the all alpha- helical GLTP-fold mechanism of action remain unclear. Previously\, reversi ble lipid-dependent dimerization was discovered for holo-GLTP [2]. Structu ral studies using synchrotron radiation indicated a homodimer\, reproducib ly revealed in different crystal forms of GLTP bound with various GSLs. Th e homodimer is characterized by a 70-80 degree angle between wild-type mon omers complexed with sulfatide\, but the inter-monomer angle narrows to 63 -66 degrees upon D48V mutation [2]. The inter-monomer contacts were found to mainly involve helix6-helix6 (H6-H6)\, as well as helix2-helix2 (H2-H2) at their C-termini. The X-ray structure of another mutant\, K87Q\, comple xed with 18:1-glucosyl¬ceramide\, reveals a novel homodimer with a differ ent dimerization contact region that includes the mutation site\, which wa s not involved in the original dimerization contact region. Fluorescence s pectroscopy assays involving intrinsic Trp emission changes show that K87Q -GLTP retains the original binding capacities for such GSLs\, as sulfatide \, glucosylceramide and galactosylceramide. Thus\, GLTP dimer design could provide a way to dissect certain steps of the glycolipid transfer process . The influence of dimer type on steps of lipid transport by GLTP needs fu rther investigation.\nThis work was supported in part by Russian Foundatio n for Basic Research project 14-04-01671 and 15-04-07415\, NIH NIGMS GM459 28 and NCI121493\, and CICbioGUNE research funds.\n\nReferences: \n1.

Some spirit compounds\, such as ethanol\, butanol\, pentanol\, glycerin e\, being biomass fermentation products\, may be used as fuel components\, both without any treatment and after catalytic converting\, that provides production of more effective fuel components.

Initial samples of ca talysts were prepared by impregnation and zol-gel methods from original mo no- and hetero-metallic precursors located on the oxide supports. All XANE S and EXAFS spectra of the studied samples were recorded at Siberian Synhr oton and Terahertz Radiation Center (SSTRC\, Novosibirsk).Genesis of the l ocal structure of the studied catalytic nanosystems was characterized in d etail. The interatomic distances and corresponded coordination numbers wer e revealed. All possible structural models were discussed.

Coal of these deposit basin is known to b e enriched by heavy metals and natural radionuclides during their geologic al origin time. So\, Th and U are significant in technogenic fallout of vi cinity. This fact is confirmed by studies results: U and Th content in aer osols and soil of HEPP vicinity are a few times greater than in pure backg round cite. \nThe second source of U fallout are the emissions of the No ¬vosibirsk Chemical Concentrates Plant (NCCP) of Rosatom State Nuclear En ergy Corporation. Namely the isotope 238U/235U ratio is used as the main i ndicator of NCCP aerosol pollution. The maximal distance of NCCP emission plume is revealed to arrive by 70 km\, where 238U/235U ratio of aerosol is 132.1  3.3. The 238U/235U increases up to about natural ratio 138.4 at 110 km far from NCCP emission northern east plume only.

This region can be a weak point in the microstru cture of the laminate composite material. Sintering route was optimized to minimize the quantity of oxides particles (basically Al2O3 particles) in order to improve some mechanical properties. The phase content of micron c omposite layers was studied by x-ray and synchrotron diffraction. X-ray di ffraction (Bragg-Brentano geometry with a flat-plate sample) showed that c omposite layers basically contain only Ti and Al3Ti phases. Synchrotron di ffraction (a transmission mode to pass through the 390 micron thickness sa mple layer) allowed to reveal the presence of residuals of aluminum phase. Also\, the frame capture mode\, using of synchrotron beam with the size 0 .4×0.1 mm\, allowed to prove the absence of Al2O3 phase particles along t he Ti / Al3Ti interfaces. \n\nDiffraction experiments were performed at th e 4-th SI-channel of VEPP-3 beam station.

During operation of such alloys in contact with a hydrogen-containing environment\, hydrogen p enetrates into them. This significantly influences on the physical\, chemi cal and mechanical properties of the material [1\,2]. To investigate the e ffect of hydrogen accumulation on the zirconium alloys properties is neces sary to prepare the experimental samples with different hydrogen concentra tions and different distribution. However\, the hydrogenation process can be hampered by the presence of a thin oxide film on the samples surface\, which is greatly effect on the hydrogen distribution by material volume. T he application of the nickel coating increases the hydrogen sorption rate. Also nickel has a high permeability to hydrogen. Moreover\, the nickel ox idation is less active than zirconium\, which contributes to hydrogen abso rption.\n\nIn this paper zirconium alloy (Zr1%Nb) samples with a micron-or der nickel layer were investigated. Hydrogenation was carried out by gas p hase method at temperatures of 350\, 450 and 550 ° C. Hydrogen pressure i n chamber was 1 atm. Hydrogen sorption curves were obtained on the automat ed complex Gas Reaction Controller. In situ diffraction measurements were carried out in the process of hydrogen saturation of samples at the statio n "Precision diffractometry II» of the Institute of Catalysis of the Sibe rian Branch of the Russian Academy of Science at the 6 synchrotron radiati on channel of the VEPP-3 electron storage ring.\n \nComparison of the data obtained in the analysis of hydrogen sorption curves with data of the pha se transitions in the zirconium-hydrogen system at a gas phase hydrogenati on allowed describing the processes occurring in zirconium by hydrogenatio n at different temperatures. \n\n1.

The ascending migration of fluids and the emanation of gases in the zones of active\, tectonic faults have a promin ent effect on the distribution of chemical elements in soil\, air\, and p lants. The impact of the active faults on biota is subjected to temporal v ariations due to seismic changes. The present work studies the content of chemical elements in the leaves of Lonicera caerulea L. (blue honeysuckle) over the region characterized by a high\, seismic activity and the novel tectonic faults related to the central part of the Chuiskii earthquake of 2003. The studies were performed in 2004\, 2008-2010 during a gradual decr ease in seismic activity in this zone. The total content of micro- and mac roelements in soil and their accumulation in vegetable leaves were determi ned by the method of X-ray fluorescence analysis using synchrotron radiati on (SR XRF) at the station of element analysis of the Siberian Center of S ynchrotron and Teraherz Radiation\, Budker Institute of Nuclear Physics (V EPP-3 storage ring). Fluorescence was excited by monochromatized synchrotr on radiation with an energy of 23 and 38 keV\, which allowed one to analyz e the elements from K to Ba by the K-series\, and from Pb by the L-one of the characteristic X-ray radiation. The concentration of an active form of the elements was measured in soil by atom-absorption method. The intensit y of the biological absorption of the elements by the leaves of blue honey suckle was estimated by the coefficient of biogeochemical activity\, i.e.\ , the ratio between the element content in the dry substance of plants an d the concentration of the active element form in soil. The SR XRF method made is possible to study the relation between 26 elements in vegetable le aves and in soils with high sensitivity (n*10-9 g/g) within a wide concent ration range in small samples (10-30 mg). A comparative estimation of the element content in the leaves of L. caerulea subsp. altaica\, collected in the zone of the active\, tectonic fault in different years\, indicated th at during the period of high seismic activity (2004) the concentrations o f K\, Fe\, Cu\, Ti\, V\, Zr\, and Nb in plants decrease and those of Ca\, Ba\, Br\, and Sr increase.

In 2005\, the samples of the P. fruticosa leaves and stems\, collected in fo ur EURT regions\, were analyzed and in 2015 the same samples were analyzed after a 10-year storage period.\nIt has been established that the element composition of the samples was almost the same. In 2005\, 18 elements wer e discovered\, and in 2015 additional two elements (Cr and Nb) were determ ined\, probably\, because of the improving potentialities of the method.\n The content of K\, Ca\, Mn\, Fe\, Co\, Cu\, Zn and Sr in the samples of 20 05 and 2015 remained practically the same.

This is achieved due to the strong distortion of metal-(O\,F) polyhedra in crystal lattice because of different ionicity of metal-O and metal- F bonds. The luminescence spectroscopy can be a sensitive method to study the character of lattice distortion of these compounds.\nSpectra of photoluminescence (PL) and X-ray excited luminescence\, PL excitation spe ctra (3–22 eV)\, PL decay kinetics as well as thermoluminescence curves were measured for single crystals and ceramics K3WO3F3. Synchrotron radiat ion (HASYLAB\, DESY\, Hamburg) were used for low temperature PL experiment s with time resolution. Crystals were grown and examined in Institute of G eology and Mineralogy SB RAS (Novosibirsk). \nThe intrinsic luminescence o f tungstates is usually ascribed to the radiative relaxation of exciton-li ke excitations localized on WO6 octahedra or WO4 tetrahedra. In K3WO3F3 th ere are anion sites with mixed oxygen/fluorine occupancy. Therefore\, diff erent octahedra form with different distortion. Two emission centers of ex citon-like origin\, with distinct relaxation time\, different types of suc h octahedra were found. The time-resolved luminescence spectroscopy techni que was applied to distinguish these centers\, proving itself as a sensiti ve method to study the character of lattice distortion. The energy transfe r mechanism between these PL centers is found and tentatively described by the diffusion of excitons. Apart from intrinsic luminescence\, the PL of defect-related centers was found in samples irradiated by fast electrons f rom linear accelerator (E=10 MeV\, D=120 Gy).

Existing t echnologies of enrichment in some cases do not correspond to the quality o f modern ores. So Russia\, having large mineral reserves\, faces difficult ies in providing new technologies that can cost-effectively and efficientl y process those materials. The decision of the problem of increasing the p rofitability of processing minerals and improving comprehensiveness of the ir enrichment are of paramount importance. One of the possible technologic al solutions is the developing approach of selective flotation separation of minerals with optimization of the proportion and properties of chemical and physical forms of sorption by combining different types of flotation reagents. One of the most popular reagents is butyl xanthate potassium\, w hich is widely used for the extraction of valuable components by flotation in aqueous solution.\nThe main aim of this work is a study of model flota tion system - xanthate/zinc sulphate by the method of XAFS spectroscopy. A ll EXAFS and XANES spectra (Zn-K edge) of the samples studied (both in sol ution and deposition) were recorded at EXAFS station of Siberian Synchrotr on Terahertz Radiation Center (SSTRC). Some differences of local structur e of initial solutions of zinc sulfate (having different concentrations fr om ~10-4 up to 10-1 mol/l) between each other and great ones compared to t he bulk samples were found. The presence of different Zn-O forms were dete cted. For the model flotation system - xanthate/zinc sulphate in aqueous s olution\, Zn-S forms were predominantly found.

This reaction is v ery important for reducing automotive and industrial emissions and conside red to be a good model for fundamental studies of transition metal catalys ts. It is known that different types of facets as well as size and shape o f a metal nanoparticle have an effect on catalyst properties. The scope of our work is to investigate how the reactivity of Pd nanoparticles towards CO oxidation depends on their size and shape. The keys to the solution ar e ab-initio DFT calculations in combination with in-situ FTIR spectroscopy . For theoretical part\, we have chosen the set of Pd clusters of differen t size and respective shape. After optimization of their geometry\, the ad sorbed CO molecules were relaxed at the top-on positions of cluster surfac e. That allowed us to generate IR spectra to be compared with experimental ones of CO adsorbed on Pd nanoparticles. In order to be closer to the ind ustrial-type processes\, a special setup allowing in-situ FTIR measurement s was designed as well. \n In our theoretical studies we used both molec ular orbital (ADF-2014) and periodic band structure (VASP 5.2) DFT calcula tion schemes to model small metallic Pd clusters. The basis in calculation s was chosen as Triple Zeta with one polarization function and frozen core . We used standard GGA approximation within PBE scheme. Occupations steep est descend method was used for better geometry convergence. All the param eters mentioned above with Scalable SCF gave good convergence in all crite ria. The cutoff energy for periodic plane wave pseudopotential simulation was set to 400eV. The cell around Palladium clusters was constructed as a cubic one with 30 nm edge. A single K-point was used in simulation.\nIn th is work we constructed and optimized geometry of Pd14 and Pd55 clusters wi th octahedral symmetry. The relaxed interatomic distances (Angstom) of Pal ladium 55 cluster with CO molecules placed on top hollow sites of Pd obtai ned by both ADF and VASP DFT calculation schemes are presented in Table 1. \n\nTable 1.

For example main peaks are at 2107 and 503 cm-1.\nBot h CO adsorption and oxidation on Pd nanoparticles have been studied extens ively with different experimental techniques [R1]. It is assumed that reac tion of CO oxidation follows a Langmuir-Hinshelwood mechanism [R2]\, where both reactants\, CO and O2\, adsorb on the catalyst surface prior to reac tion between the adsorbed species to form CO2. There were also found some differences in the kinetics among the (111)\, (110)\, and (100) planes in studies on single crystals of Pd [R3]. Significant number of experimental studies of CO adsorption on surface of Pd have been performed by using Dif fuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS). DRIFTS is a useful technique for probing catalysts at catalytically relevant temp eratures and pressures without intense sample preparation [R4]. \nOur expe rimental setup for in-situ DRIFT studies of CO adsorption on Pd nanopartic les as main components includes Vertex 70 FTIR spectrometer\, Praying Mant is Diffuse Reflection Accessory equipped with Low and High Temperature Rea ction Chambers and a two-channel gas mixing system assembled by using the Swagelok tube fittings.\n\n\nReferences\n\n[R1] Janos Szanyi\, W.

The mai n attention was paid to changes in the temperature of the Debye. The struc ture factor equation given earlier yields the diffracted intensities as th ough all atoms were stationary. As the temperature rises the atoms execute increased excursions from their average position. Such excursions can inv olve complex coupled motions of several atoms. However if one restricts co nsideration to just the independent motions of each atom there is a relati vely simple trick that can be used which is to (artificially) modify the a tomic scattering factors\, f\, of each atom to represent the net broadenin g of their electron clouds resulting from atomic motion. For example a giv en atom will have its "stationary" f changed to fT according to: fT = f ex p(−B sin2θ / λ2) where T is the temperature and B = 8π2u2 (units of A 2 )\, u2 being the root mean square displacement of the atom from its aver age position. The B values are often referred to as B factors (Debye-Walle r is a another\, similar\, term often used) and increase with temperature (typical values are 0.2 to 0.8 A2 ). So clearly temperature will modify th e diffraction intensities by changing the various values of f to fT in the structure factor equation.\nTo determine the Debye powder X-ray series wa s filmed at different temperatures of the polyethylene samples irradiated by relativistic electrons.\nThe method allows to monitor the changes in th e structure upon irradiation.\n\nhttps://indico.inp.nsk.su/event/3/contrib utions/1256/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1256/ END:VEVENT BEGIN:VEVENT SUMMARY:The formation of silver nanoparticles by synchrotron radiation and relativistic electrons irradiating of water solution of silver salts DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1257@indico.inp.nsk.su DESCRIPTION:Speakers: Boris Tolochko (Institute of solid state chemistry a nd mechanochemistry)\nIt has been found that irradiation of aqueous soluti ons of silver salts by synchrotron radiation start formation of silver nan oparticles.

Control unit of the electronic part is based on AVR micro controller ATmega 2560 with 10-bit analog to digital converter. It allows having up to 120 measurements per minute with 2 mV and 1 mA accuracy. Cont rol of the power circuit is realized via 8-bit external multichannel digit al to analog converter. In addition\, there is on-board USB-COM Bridge for communication with specially designed computer software. This software p rovides control of work regimes. Main functions are charge or discharge of the battery\, measurement of capacity\, measurement of the level of charg e\, cycling the battery with specific current in needed range of voltage a nd charge or discharge to specific capacity.\n\n The second part is a spe cial cylindrical cell consisting of two parts with thin replaceable conduc ting and X-Ray transparent windows.

I t is a well known fact that metallic gold is most inert among the precious metals due to its electronic structure\, nevertheless the nanosized Au\, Au-Me forms located on oxide supports may be used as very active catalysts for numerous industrially important reactions. These systems are very pro mising for complex organic synthesis\, selective isomerization reactions and for processes of environmental catalysts\, such as\, CO oxidation and selective conversion of secondary alcohols. Reliable analysis of the natur e of gold forms is extremely important for design of new effective gold ba sed catalysts for different industrial applications. Synthesis of low-perc entage ~ 0.2-2% Au\, Au-Me samples was carried out under varying preparati on methods (impregnation\, deposition-precipitation with urea\, direct ion exchange)\, calcination temperatures and activation methods. All XAFS spe ctra (Au-L3 edge) of the studied samples were recorded at SSTRC\, Novosibi rsk. The state of metal components and the local Au structure arrangements of the prepared catalysts were studied. The Au-O\, Au-Au\, Au-Me interato mic distances and corresponded coordination numbers were established. All possible structural models were discussed. It was shown that different sta bilized gold forms located on oxide supports were formed\, most probably d epending on a sample prehistory: Au(3+) cations\, having octahedral oxygen surrounding and metallic Au-Au\, Au-Me nanoparticles ~10-100Å. Some corr elations between catalytic activities and structural functional properties of the studied samples were shown. Additionally\, samples of catalysts we re characterized by the TEM\, EDX\, XRD\, XPS methods.

Structural study of biological tissues b y X-ray diffraction methods with synchrotron radiation usage were carried out on constructed by us small-angle station «diffraction cinema» DICSI at the NRC «Kurchatov institute»\, Moscow. \nConsiderable distinctions o n X-ray patterns of thin intestine tissues are registered before and after HF welding: the X-ray patterns of native tissue display a small-angle dif fuse scattering\; diffraction lines practically do not reveal. After appli cation of HF welding\, the small-angle X-ray patterns of welded sutures in intestinal tissue are literally filled with sharp diffraction rings: a se ries of sharp Debye rings with main spacing of 4.65 nm was recorded within the nanoscale range of 10 to 0.4 nm. We earlier attributed the nanostruct ural invariant of 4.65(±0.15) nm as periodicity caused by regular attachm ent of oligosaccharide chains to the protein core of giant proteoglycan mo lecule of mucus and extracellular matrix of tissues [A. Vazina et al.\, B ullet. RAS\, 2013\, 77(2)]. \nConsiderable changes in X-ray patterns of ga strointestinal tissues under synergistic influence of various parametres o f welding (temperature\, toolkit geometry\, pressure\, modulation of an el ectromagnetic field\, etc.) can be interpreted by increase in concentratio n of scattering components due to cold steam formation at acoustic excitat ion of a site of a tissue between electrodes. \nThus\, under the influence of welding in tissues it is formed high ordered proteoglycan scaffold pro viding the functional arrangement of cells during reparation. Proteoglycan systems can be not only a marker of the physiological status of a tissue\ , but also a regulator providing adequate adaptation of biological systems to change of external parametres of environment. \nThe research was suppo rted by RFBR-Moscow region Grant #14-44-03667.\n\nhttps://indico.inp.nsk.s u/event/3/contributions/1261/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1261/ END:VEVENT BEGIN:VEVENT SUMMARY:Structure and properties of ZnSxSe1-x alloy nanostructures embedde d in anodic alumina membrane DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1262@indico.inp.nsk.su DESCRIPTION:Speakers: Andrey Chukavin (Physical-Technical Institute of Ura l Branch of RAS)\nZnSxSe1-x alloys\, as an important member of II–VI ter nary semiconductors\, have attracted significant interest until now due to their variable band gap\, spanning from 2.7 eV to 3.67 eV\, which makes t hem appropriate for developing short wave length LEDs and laser diodes ope rating entirely in the blue–violet region. Recently\, the ZnSxSe1-x allo y nanostructures were synthesized by a variety of methods such as chemical vapor deposition (CVD) and metal organic chemical vapor deposition [2-4]. The electronic structure and band gap of ZnSxSe1-x were also discussed [5 ]. The design of ZnS ySe1-y/GaAs (001) heterostructures and their dynamica l X-ray diffraction were reported [6\,7]. It is worthy to note that the 1D ZnSxSe1-x-based ZnO/ZnSxSe1-x core/shell nanowire arrays\, ZnO/ZnSxSe1-x/ ZnSe double-shelled heterostructure and ZnS/ZnSxSe1-x nano-heterostructure s have also been synthesized by chemical vapor deposition method or magnet ic force assistant growth technique\, which exhibit efficient visible ligh t absorption\, enhanced photoelectrochemical performance and integrating e mission property\, respectively [8–10]. However\, the data on the optica l absorption and photoluminescence spectra yielded different results for t he ternary compounds produced by different methods\, and understanding of the physical mechanism leading to this controversy is still not achieved.\ nThe semiconductor nanostructures in dielectric matrixes are of current in terest due to absorption and luminescent properties improved in comparison to thin films of materials [11\, 12]. In nanocrystals\, the surface-to-vo lume ratio is considerably large\, therefore there is a high contribution of surface in the luminescence properties. The unsaturated bonds on the su rface create band-gap states that can easily capture the excited electrons and holes and relax the energy in non-radiative ways [13]. In addition\, matrix isolation allows to protect nanostructures from external influences .\nIn this work we for the first time have successfully synthesized alloye d ZnSxSe1–x nanowires embedded in a anodic alumina membrane via thermal evaporation of the mixture of ZnS and ZnSe powders. Various compositions c an be easily obtained by changing the mole ratio of ZnS to ZnSe in a sourc e material. The X-ray diffraction patterns show that the lattice structure of these nanostructures is cubic ZnSe-like\, as S atoms replace Se and na nostructures compositions correlate with their initial S/Se ratio. Chemica l composition was controlled by XPS method. Optical absorption spectra sho w that band gaps of the alloy cover the entire range from 2.7 eV to 3.67 e V by changing the component ratio\, in agreement with literature. The stud y of the local atomic structure was carried out via EXAFS method. The set of structural parameters\, namely the interatomic distances and correspond ed coordination numbers\, were established. All possible structural models were discussed in detail. Additionally ZnSxSe1–x samples were character ized by the TEM\, EDX and XPS methods. The data obtained by all the method s are in a good agreement.\n\n 1. Y. Liang\, H. Xu\, S. Hark\, // Cryst.

Up to date\, the e ffect of the electrochemical synthesis conditions on the chemical structur e and molecular orientation in the films is far from being comprehensively studied. In the work\, the polarization-dependent NEXAFS spectra were use d to obtain the data on the molecular arrangement in a relatively thick (~ 1 micron and thicker) polyaniline films. The influence of different parame ters of electrosynthesis was investigated such as polarization potentials\ ; polarization modes (potentiostatic\, cyclic)\; growth from still/stirrin g electrolyte solution. XPS and NEXAFS spectra were measured at the dipole Russian-German beamline at the BESSY II\, HZB Berlin.\n\nIn most films\, the polarization-dependent NEXAFS spectra have shown a preferential orient ation of the macromolecular chains of polyaniline in the surface layer of the films. The films are arranged differently depending on the preparation conditions. For example\, at the initial stages of the deposition under p otentiostatic conditions in stirring electrolyte\, most of the aromatic ri ngs of the polymer molecules are arranged along with the film surface. Wit h increasing deposition time\, a preferential molecular orientation disapp ears. For the film prepared under the same conditions\, but in still elect rolyte\, there is significant polarization effect\, indicating that the ar omatic rings are arranged perpendicular to the sample surface. However\, t he polymer chains themselves are oriented along with the sample surface. S uch an orientation of the molecules can be assigned to the capture of macr omolecular fragments and oligomers from the near-electrode layer\, in whic h these fragments are accumulated.\n\nThe work was supported by the Russia n Foundation for Basic Research (grant № 16-43-180228) and the Russian-G erman Laboratory at BESSY II\, HZB Berlin.\n\nhttps://indico.inp.nsk.su/ev ent/3/contributions/1268/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1268/ END:VEVENT BEGIN:VEVENT SUMMARY:MANUFACTURING LIGA-MASKS WITH LASER MICROMACHINING DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1269@indico.inp.nsk.su DESCRIPTION:Speakers: Aleksandr Gentselev (Budker INP\, Novosibirsk\, Russ ia)\nIn the LIGA-technology\, the first stage in forming a micro-relief is the deep X-ray lithography which is implemented\, as a rule\, by using sy nchrotron radiation (SR) of the wavelength spectral range λ ≈ 1÷3 Ǻ. Realization of this technology implies availability of a high-contrast X-r ay mask (LIGA-mask) containing X-ray opaque topological drawing which is n ormally formed via galvanic deposition of heavy metals on the surface of a X-ray transparent bearing membrane.

Light e mitting electroluminescent panels based on powders and thin films have fou nd wide application in electroluminescent devices\, character displays\, b acklight panels of advertising constructions. One major drawback of such d evices is using high frequency and high voltage AC power sources. Traditio nal materials for electroluminescent light sources are powders and films o f zinc sulfide doped with copper\, chlorine\, manganese and other elements . It was established that a wavelength and intensity of light depends on t he concentration and type of dopands\, i.e. there are circumstances under which it is possible to provide a source of white light emission. But alon g with the advantages of electroluminescent light sources\, there are sign ificant disadvantages: high energy consumption\, the need for specific pow er supplies and short operation time. This is due to degradation of the ac tive layer under specific principles of operation of such devices in extre mely high electric fields (before breakdown luminescence). \nIn this work we use templating approaches based on the formation of doped ZnS particles in the porous alumina membranes with highly ordered channels with control led diameter.

Nickel sta nds out among them because of the fact that\, having high corrosion resist ance in acidic and alkaline media compared with platinum group metals\, it has a low cost and so is widely used [2\,3]. It should be noted that the efficiency of HER depends on the area of contact of the cathode material w ith the electrolyte\, so there is an increased interest in literature to t he nickel based materials having a developed surface due to the formation of metal nanoparticles with different morphology [4]. This is due to the l arge contribution of surface electronic states of the metal in HER. It is also strongly affected by the structural-phase state and local atomic and electronic structure causing nickel chemical activity.\nThe aim of this wo rk is to develop methods of magnetron sputtering nickel on high surface ar ea membranes of a porous anodic alumina morphology and to study the struct ural-phase state\, local atomic and electronic structures of the samples\, depending on the parameters of the Al2O3 porous structure (the pore diame ter\, the distance between the individual pores). \nAs a result of a compl ex study (XAFS\, XRD\, SEM)\, the state and local structure of samples obt ained by few ways were revealed. The geometrical characteristics of Ni nan ostructures\, their crystalline and local atomic structure were studied.

We did that for cases with different resolutions\, to study the pla usibility of the results of solving the deconvolution problem. We also ana lyzed the influence of certain effects that cause systematic errors in the calculations and the resulting solution.\n\nAs a result of this work\, we found out that it was very difficult to practically increase the spatial resolution 3 times (which corresponds to the distance between the gold str ipes of the sample and their width of 5 μm at an FWHM of the lens instrum ental function of 15 μm)\, while it was theoretically possible\, on the " SR micro-XRF" installation with the available intensities of fluorescent s ignals and noise levels. A quantitative analysis of the reasons for this i s discussed in this work and illustrated in detail in a number of model ca ses. At the same time\, in certain experimental mapping regimes\, the achi evable resolution can be increased 1.5-2 times (provided there are no sign ificant systematic errors in the calculations).\n\nThe results of the rese arch will help to plan subsequent mapping experiments (they showed that th e data of the mapping conducted earlier were ill-suited to processing beca use of non-optimal experimental regime\, which led to a substantial system atic error with the desired 3-fold resolution increase\, because of the ed ge effects and not too good signal-to-noise ratio).\n\nThis work was suppo rted by the RFBR Grants № 14-02-00631\, 16-32-00705.

So rokoletov was supported by a scholarship of the President of the Russian F ederation (SP-2761.2016.2).\n\nReferences\n\n[1] http://ssrc.inp.nsk.su/CK P/stations/passport/3/\n\n[2] Sorokoletov D.S.\, Rakshun Ya.V.

Namely\, the developme nt of manufacturing methods of X-ray rasters with high aspect ratio and\, on substrates of any forms\, using LIGA technique. \nA spherical X-ray wav e can be formed\, placing a foil with microchannels onto a spherical surfa ce either near the X-ray focus or away from the focus. In case of a plane raster\, the quasi-plane wave with a divergence determined by the ratio of the diameter to the lengths of channels will be formed. At the same time\ , for X-ray tubes of all the types\, including flash generators applied at the Institute of Hydrodynamics SB RAS for the diagnostic of high-speed an d explosive processes\, a three-dimensional microraster can be used as a c ollimator. That allows a decreasing of the visible source size\, resulting in an increasing of the spatial coherence of the X-ray beam. \nIn the exp eriment\, a flat nickel raster of 1250 microns thick\, whose channels are 80 microns in diameter\, and manufactured using LIGA technique\, has been applied. For a flash X-ray device with an explosive electron emission and a bias of 150 kV\, the angular divergence was reduced from 180 degrees to 3 degrees (FWHM)\, i.e. 60 times. The quasi-parallel X-ray beam along the axis passing from the center of the focus and perpendicular to the raster was formed. The beam diameter is similar to the focus size in the near fie ld and divergent (with an angular divergence of 3 degrees) in the far fiel d.\nBecause of non-zero raster transparency\, a background of scattered ra diation has been observed. The intensity of the background is characterize d by the sixth order of symmetry that corresponds to the raster symmetry. \nThus\, the opportunity of the use of microraster manufactured by means o f LIGA for the increase of spatial coherence of X-rays is experimentally d emonstrated.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1285/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1285/ END:VEVENT BEGIN:VEVENT SUMMARY:IN-SITU INVESTIGATION OF THERMO-STIMULATED DISSOLUTION OF HYDRIDES IN TITANIUM AND ZIRCONIUM BY MEANS OF SHORT-WAVE DIFFRACTION OF SYNCHROTR ON RADIATION DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1287@indico.inp.nsk.su DESCRIPTION:Speakers: Roman Laptev (National Research Tomsk Polytechnic Un iversity)\nTitanium and zirconium alloys are widely used in medicine\, che mical and oil industries\, aircraft industry\, in nuclear power industry. Hydrogen penetration and accumulation in titanium and zirconium products l ead to its properties and can lead to the delayed fracture due to the hydr ogen embrittlement [1-4].\n\n Degree of hydrogen impact on the titanium an d zirconium properties depends on its concentration and condition in metal . Hydrogen saluted in lattice has a low impact on properties of the metal. However\, hydrogenation under operation of titanium and zirconium alloys often occurs with hydrides formation. As a consequence\, investigation of hydrides formation and dissociation in titanium and zirconium has both fun damental and practical interest.\n\nSamples of commercially pure titanium alloy and Zr1%Nb zirconium alloy were instigated in this work. Hydrogenati on was done by gas-phase method at temperature 600 °C and hydrogen pressu re 1 atm. Spectrum of hydrogen thermo-stimulated desorption from samples a fter hydrogenation were obtained with the help of automated complex Gas Re action Controller LPB with mass-spectrometer RGA100. \n\nIn situ diffracti on measurements were carried out in the process of samples heating at the station "Precision diffractometry II» of the Institute of Catalysis of th e Siberian Branch of the Russian Academy of Science at the 6 synchrotron r adiation channel of the VEPP-3 electron storage ring. \n\nComparison of th e data obtained in the analysis of hydrogen desorption curves with data of the phase transitions in the zirconium-hydrogen and titanium-hydrogen sys tems at the heating allowed describing the processes occurring in zirconiu m and titanium hydrides under thermal treatment. \n\n1.

The aim of this study is to investigate the effect of the structural changes on the catalytic prop erties of the material. We investigated the structural evolution of the in dustrial palladium-based nanocatalyst in operando conditions during the ca talytic hydrogenation of ethylene. The structure of the catalyst was follo wed by X-ray absorption spectroscopy and X-ray powder diffraction\, while the conversion level of ethylene to ethane was controlled by mass spectrom eter. We observed that phase transitions occurring in palladium nanopartic les lead to dramatic changes of the catalytic activity. In addition to sta ndard Fourier-analysis of X-ray absorption data and Rietveld refinement of diffraction patterns\, analysis of X-ray absorption near-edge structure ( XANES) allowed to discriminate between PdH and PdC species having similar fcc structure.

At one method the collimated X-ray beam of polychromatic radiation ("white spectrum") is directed on the object\, and the diffraction pattern represent the intensity distribution as functi on of a wavelength at the fixed scattering angle (Θ)\, i.e. lattice-plane spacing of object are uniquely determined by a discrete set of the photon energy. Note the spatial resolution of different zones of the X-ray patte rn can be changed by varying Θ value that allowed to record weak reflecti ons and to register X-ray pattern with high resolution for material with l arge spacings of identity. The ‘λ=const’ method determines by dedicat ed monochromatic wavelength from continuous SR spectrum\, and then the X-r ay beam is collimated by X-ray optical zoom lenses\; obtained diffraction patterns demonstrate the intensity distribution as a function of scatterin g angle. The ‘Θ=const’ method provides increasing intensity of the X- ray beam on 2-3 orders\, however earlier during creation of the first SR s ources these advantages were unattainable because of under quick-action of the detection system. The ‘λ=const’ method is traditionally used wit h position sensitive coordinate detectors. Now power-dispersion detectors with high performance of registration and energy resolution are developed\ , therefore it is very inviting to use polychromatic radiation.\nVarious X -ray diffraction stations created by us (KEMUS\, FRAKS\, DICSI) on the ope rating channels of the storage rings VEPP-3\, VEPP-4 (Siberian Center of S ynchrotron and Terahertz Radiations\, SCSTR\, Novosibirsk) and Siberia-2 ( Kurchatov Center of Converging of Nano-\, Bio-\, Information-\, and Cognit ive Sciences and Technologies\, NBIC\, Moscow) are presented.

This definition covers major scien tific equipment or sets of instruments\; knowledge-based resources such as collections\, archives or data banks\; e-Infrastructures (networks\, comp uting resources\, software). \n Some research facilities\, particularly in physics or astronomy (called global research infrastructures - GRI) are so large\, complex or expensive that they require international cooperati on for construction and operation and it is being impossible for one count ry or region alone to build and operate these facilities. The examples of GRIs are CERN: the European Organization for Nuclear Research\; JINR: the Joint Institute for Nuclear Research\; ESRF: European Synchrotron Radiatio n Facility\; SKA: Square Kilometer Array\, the next generation radio teles cope. \n The efficient planning\, design\, construction and operation of the global research infrastructures requires not only a sharing of costs\ , but also the sharing of knowledge. A Group of Senior Officials (GSO) on GRIs established in 2008 strives to reach a common understanding on matter s such as governance\, funding and management of global research infrastru ctures. Russia is the member of the GSO group. \n According to the last GSO Progress report 2015\, the current list of the national based research infrastructures of global interest covers 39 RIs from 14 countries\; amon g them there are six Russian Mega science projects. \n A key area of R ussia-EU S&T cooperation involves the joint development of GRIs. Russia is a partner of a number of research infrastructure initiatives located in E urope: the EU X-ray Free-Electron Laser (XFEL)\; the Facility for Antiprot on and Ion Research (FAIR)\; the International Thermonuclear Experimental Reactor (ITER)\; the Large Hadron Collider (LHC\, CERN)\; the European Syn chrotron Radiation Facility (ESRF). All these projects have a global dimen sion and participants and are located on the roadmap of ESFRI\, the Europe an Strategy Forum on Research Infrastructures.\n Since its foundation in 2002\, ESFRI has played a leading role in coordination of research infras tructures across Europe and development of integrated and coherent approac h for policy making in this field. \n The new ESFRI roadmap 2016 consist s of 21 ESFRI Projects with a high degree of maturity and 29 ESFRI Landmar ks - RIs that reached the implementation phase by the end of 2015. The Lan dmarks in the area of physical sciences and engineering cover 11 internati onally well-known facilities: E-ELT –European Extremely Large Telescope\ ; ELI- European Light infrastructure\, EMFL- European magnetic field labor atory\; ESRF UPGRADES\; European spallation source\; European XFEL\, FAIR\ , HL-HLC\; ILL20/20\, SKA\; SPIRAL 2. The impact of many of the ESFRI rese arch infrastructures is global and this has prompted a reflection in two m ain fora: the Global Science Forum of OECD and the GSO group tasked with d efining a strategy for GRIs. \n Developing excellent RIs for physical sc iences and engineering is one of the top European priorities. Bringing tog ether scientists and users of the Europe’s major projects with their cou nterparts all over the world has an intention to generate new synergies th at will stimulate a truly global integration of existing infrastructures.

In situ XRD experiments showed that YPDC cell reversibly expands after change to the lower pO2 at 500-600C due to the oxygen loss while YDC didn't show any significant structure changes. For the Pr6O11 the following structure changes were observed at the same conditions: monoclinic → cubic → tr igonal.\n\nWe also estimated the oxygen mobility coefficients(kchem - oxyg en surface exchange coefficient and Dchem - oxygen chemical diffusion coef ficient) of all samples by analysis of the cell volume relaxation (CVR) cu rves obtained from the XRD data after abrupt change of the oxygen partial pressure from 100 mBar to 10 mBar. Since no relaxation was observed for YD C\, kchem and Dchem could not be calculated. For YPDC process is limited b y surface exchange thereby only kchem could be calculated. The following k chem values were determined for YPDC 1.3*10^(-4) cm/s at 500 °C and 1.6*1 0^(-4) cm/s at 600 °C. For Pr6O11 both kchem and Dchem could be calculate d simultaneously and were about 5.0·10^(-4) cm/s and 5.0·10^(-7) cm^2/s at 500 °C.\n\nIn situ XRD experiments were carried out with involvement o f equipment belonging to the shared research center “SSTRC”.\n\nhttps: //indico.inp.nsk.su/event/3/contributions/1302/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1302/ END:VEVENT BEGIN:VEVENT SUMMARY:MECHANISMS OF COMBUSTION AND STRUCTURE FORMATION IN SHS- SYSTEMS W ITH PARTICIPATION OF TWO AND MORE CHEMICAL REACTIONS DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1303@indico.inp.nsk.su DESCRIPTION:Speakers: Evgeny Levashov (National University of Science and Technology "MISiS")\nThe mechanisms of combustion and structure formation in perspective systems Ta-Ti-C\, Mo-Si-B\, Ta-Zr-C\, Zr-Si-B\, Ti-C-Ca3(PO 4)2\, Cr-Al-Si-B\, Si-C-B were well characterized using a combination of v arious techniques including dynamic XRD\, stop combustion front\, SEM\, TE M\, Raman spectroscopy\, etc. \nIt was established that gas transport reac tions is to control the combustion in some cases. In system (100%–X)(Ti+ 0\,5C) + X(Ta+C) with X= 10 and 30% an abrupt increase of Uc and Tc occur s as a result of the transfer from the splitting to merging mode\, which i s accompanied by an increase in heat release as a result of two parallel c hemical reactions. In the case of X= 50%\, dependences Tc(T0) and Uc(T0) a re linear over an a wide range of T0. \nThe following processes are defin ed the SHS for Si-rich Mo-Si-B compositions: silicon melting\, its spreadi ng over the surfaces of the solid Mo and B particles\, followed by B disso lution in the melt\, and formation of intermediate Mo3Si-phase film. The s ubsequent diffusion of silicon into molybdenum results in the formation of MoSi2 grains and molybdenum boride phase forms due to the diffusion of mo lybdenum into B-rich melt. The formation of MoB phase for B-rich compositi ons may occur via gas-phase mass transfer of MoO3 gaseous species to boron particles. The stages of chemical interaction in the combustion wave are also investigated. The obtained results indicate the possibility of both p arallel and consecutive reactions to form molybdenum silicide and molybden um boride phases. Thus the progression of combustion process may occur thr ough the merging reaction fronts regime and splitting reaction fronts regi me. Molybdenum silicide formation leads the combustion wave propagation du ring the splitting regime\, while the molybdenum boride phase appears late r.\nKinetics of the SHS process\, stages of chemical transformations and s tructure formation of ceramic materials in the Cr-Al-Si-B system were inve stigated. The effect of green mixture composition and initial temperature on the combustion rate Uc and combustion temperature Tc\, which reduce wit h increasing Al content\, was studied. An increase in the initial temperat ure of the SHS process causes a linear increase of Uc and Tc in the range of T0 = 290–750 K. This is a fact that each composition is characterize d by the similar combustion mechanism\, when the stages of chemical reacti ons of product formation remain unchanged. However\, an increase in T0 abo ve 750 K\, probably\, may lead to exponential character of Uc growth. Furt hermore\, an increase in Al content increases the proportion of the Al–S i eutectic melt. The stages of chemical transformations and the mechanism of structure formation in the combustion wave were studied. \nDependences Tc(T0) and Uc(T0) of mechanically activated (MA) Ta-Zr-C exothermic mixtur es were determined. The self-heating phenomenon is observed in argon atmos phere at T0 > 380 K due to zirconium particles oxidation by adsorbed oxyge n. ZrO2 was formed in the combustion zone at the initial stage of chemical interaction\; it is subsequently transformed into ZrC. TaC was formed in the combustion zone\, while the single-phase (Ta\, Zr)C with the lattice p arameter of 0.4479 nm was formed closer to the post-combustion zone.\nKine tics and mechanism of SHS process\, stages of chemical transformation and structure formation in systems Zr-Si-B\, Ti-C-Ca3(PO4)2\, Si-C-B were also discussed.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1303/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1303/ END:VEVENT BEGIN:VEVENT SUMMARY:The new control for magnet system of KCSR.

Such resolution\, available in qualitative micro-XRF (mapping o f fluorescent signal distribution or exploration of area of interest witho ut detailed consideration of effects caused by absorption by a sample) is defined by the transverse size of the focal spot of x-ray optics used. As a rule\, up-to-date (monolithic) polycapillary lenses are applied. This q ualitative elemental mapping in some cases can provide useful information. It can be in demand\, for example\, in reconstruction of paleoclimate (la yered samples of bottom sediments\, so called varves) and conditions of ro ck formation in deposit occurrences\, as well as in examination of biolog ical objects (hair and large cells)\, particles of earth and meteorite dus t and some other objects [1-2].\n\nThe SR XRF experimental station on the VEPP-3 storage ring (the SCSTR) [3] is equipped with the installation "SR micro-XRF"\, which is intensely used by a number of users in most of these areas of research. The installation was engaged in an extensive series of experiments [3] using qualitative SR micro-XRF\; unique results were obta ined in several cases. Two directions of improving the method and installa tion were selected so far. The first one is development of certified techn iques of (semi-) quantitative XRF\, and the second one is 1.5-2 time impro vement of the spatial resolution due to application of complicated algorit hms to process experimental data (so called regularization)\, including em bedded indirect accuracy control.\n\nRegularization is a method of approxi mate solution to unstable inverse problems. It is based on certain control led introduction of systematic error into the result. This error is introd uced so that its contribution optimally balances [4\, p. 52-55] the influe nce of random noise\, because of which the problem cannot be accurately so lved by traditional methods. Development of any regularization algorithms implies analysis of feasibility of the above rule (in other words\, the co nvergence of the approximate solution) over the entire range of all input parameters. The algorithm user is assumed to know the rules for use of one or another regularizing procedure (that may expect\, for example\, normal distribution of noise\, absence of systematic errors\, special prior cons traints to the solution\, and others) and adhere to them. Unfortunately\, this is not always the case\, and application of regularization of algorit hms is often blind and inefficient\, especially when third-party programs are used.\n\nThis work presents an attempt of non-strict but effective pra ctical analysis of the influence of various factors "hindering" the regula rization (inaccuracy in the determination of the instrumental function\, d iscretization errors\, Gibbs boundary effects etc.) on the process of solv ing inverse deconvolution problems arising in SR micro-XRF using the Tikho nov algorithm [4\, p. 52]. The analysis performed resulted in practical re commendations on the optimal regimes of experiment with improved spatial r esolution and highlighted the role of numerical simulation in the control of solving real inverse deconvolution problems.\n\nThis work was supported by the RFBR Grants № 14-02-00631\, 16-32-00705.

This is due to the ability of humic acids to accumu late\, deposit\, and store carbon and a wide range of trace elements for l ong\, geologically-comparable periods\, as well as inhibiting chemical com pounds toxic to living organisms. The content of humic acids in soils and natural and man-made deposits is ambiguous. The amount of humic acids can often be deciles (or even less) of percent. This means handling of very la rge masses\, up to a kilogram or more\, of soil samples to study. This\, i n turn\, limits the possibility of quantitative research to identify the e cological state of the environment. Since the extracted preparations of hu mic acids have a weight of milligrams\, there arises a problem of non-dest ructive methods for their investigation and creation of base of preparatio ns of humic acids for their further study.\nTesting of different methods o f analysis (NAA\, two-jet arc plasma AES etc.) for determination of the tr ace element content in humic acids resulted in a conclusion that X-ray flu orescence analysis using synchrotron radiation (SR XRF)\, which a non-dest ructive and multi-element method\, fits the best to a wide range of proble ms concerning the condition of the natural environment. It is particularly important to identify elements such as As\, Se\, Br\, Rb\, Sr\, Y\, Zr\, Mo\, I\, Pb\, Th\, and U\, determination of which in humic acids by other methods may be difficult or unreliable. Thus\, the use of SR XRF in identi fying a wide range of trace elements in humic acids enables\, first\, usin g weights of a few milligrams\, secondly\, extension of the possible range of elements to identify\, and\, finally\, storage of preparations of this natural component\, which is very significant in the functioning of the b iosphere\, for further research.\n\nhttps://indico.inp.nsk.su/event/3/cont ributions/1312/ LOCATION:Budker INP 2nd and 3rd floors URL:https://indico.inp.nsk.su/event/3/contributions/1312/ END:VEVENT BEGIN:VEVENT SUMMARY:Mercury in ancient organic materials (Noin-Ula\, Mongolia): EDXRF\ , SRXRF and micro-SRXRF analysis DTSTART;VALUE=DATE-TIME:20160705T090000Z DTEND;VALUE=DATE-TIME:20160705T100000Z DTSTAMP;VALUE=DATE-TIME:20260711T060730Z UID:indico-contribution-137-1313@indico.inp.nsk.su DESCRIPTION:Speakers: Valentina Zvereva (Nikolaev Institute of Inorganic C hemistry SB RAS)\nRecently the anomalously high content of copper in ancie nt hairs in royal burials of Xiongnu (I B.C. – I A.D.\, Northern Mongoli a) was discovered.

The results revealed the exogenous source of copper in ancient hairs and allow to exclude copper po isoning in lifetime [1]. There were 40 hair plaits in ancient burial site. Mercury was detected in all hair samples (up to 1200 ppm). High content o f Hg may be caused by the burial environment as well as the accumulation i n lifetime. Information\, which can elucidate the probable cause of such a high Hg content in hairs\, can be helpful in reconstruction of culture\, life and technologies of ancient people. \nThe unique archaeological mater ial demands nondestructive analytical methods\, as SRXRF analysis and X-ra y microanalysis (µSRXRF). \nSRXRF methodology for Hg det ermination in archaeological hair samples\, mercury concentration in metal lic objects from the burial\, and information on cross-section distributio n of Hg in hair strand (µSRXRF) allow to determine probable source of mer cury in ancient hairs. \n\n[1].

These systems are also possess thermoelectric properties. In vention of a highly efficient thermoelectric materials is one of the impor tant direction of modern materials science. One of the directions on findi ng of new thermoelectric materials is the study of systems\, in which met al-dielectric transition is observed. The systems of such kind could be so lid solutions based on the transition metal sulfides Mn1-xMxS (M=Cu\, Fe\, Co) and possess high values specific of thermoelectric power [4-5].\n Electrophysical properties of such functional matrials is primarily deter mined by features of its electronic structure.
