Nowadays the method of XAFS spectroscopy in a different methodical options using of SR sources is a recognized powerful tool to study the state of the elements and the local structure for the various nanosystems having different aggregation: alloys, high dispersed material, semiconductors, solutions, glasses and others. In this report, by the example of works performed at the EXAFS station of SS ... More

Chalcopyrite CuFeS2, is the most common mineral of copper; chalcopyrite and related compounds are of interest for thermoelectric, photovoltaic and other applications. We also examined valleriite (Fe,Cu)S(Mg,Al)(OH)2, natural nanocomposite composed of chalcopyrite-like Fe,Cu sulfide layers and brucite-like oxide layers, which is important mineral of Norilsk ore deposits. Conventional XPS and synchr ... More

We present an element-specific magnetizations study of the multiferroic Nd0.5Ho0.5Fe3(BO3)4 single crystal. Our experimental results confirm the coexistence of three magnetic subsystems (Fe, Ho, and Nd). It was found that the Ho magnetic moment undergoes the pronounced spin-reorientation transition. At the magnetic ield (less than 1 T) the Ho and Nd magnetization curves demonstrate different of th ... More

The material under study is manganese borohydride Mn(BH4)2. The unique thermodynamics and kinetic properties in combination with high volumetric and gravimetric hydrogen densities make this compound a very promising candidate to solid state hydrogen storage. Local atomic structure of Mn(BH4)2 upon heating was completely studied by in-situ temperature-dependent measurements of X-ray powder diffract ... More

The aim of the present project is to characterize the charge state, electronic and local atomic structures of Pt in the key chemical systems, critically important for ore geology, geochemistry, and for material sciences. This project will benefit from our experience in the synthesis and crystal growth of chalcogenides. Using the novel synthesis methods developed by members of our team we have synt ... More

Some of the EXAFS spectra above Ga*K*-and Ge*K*- edges were measured at the VEPP-3 storage ring (beamline 8) of Siberian Synchrotron and Terahertz Radiation Center (SSTRC) of the Budker Institute of Nuclear Physics (BINP SB RAS, Novosibirsk, Russia). Other part of the spectra was measured at the ESRF (Grenoble, France). The high energy resolution fluorescence detected HERFD-XANES and EXAFS experim ... More

Recently, low-content supported mono- and bimetallic catalytic nanosystems containing transient and noble metals inspire great interest in researchers, because of their practical application for a wide range of processes of environmental catalysis owing to the possibility of varying catalytic properties, relatively low cost of the final products, and ease of recovery of expensive components of the ...
