DESCRIPTION:Speakers: Vladimir Kriventsov ()\nThis work shows the results 
 of the study of trial test samples of technological and natural origin\, a
 nd using a complex composition for the development of combined methods bas
 ed on synchrotron radiation (SR)\, such as μ-XANES/EXAFS\, μ-XRF\, and o
 thers. Main goal of the study is to adapt the developed integrated approac
 h for the study of micro-inclusions and microparticles by SR methods in th
 e near future. All the spectra of the studied samples were recorded using 
 standard methods\, both at the experimental module of x-ray confocal micro
 scopy located at NRC “Kurchatov Institute” (Moscow) and at XRF-\, EXAF
 S- stations of Siberian Synchrotron Terahertz Radiation Center (SSTRC\, No
 vosibirsk).\nThe studied test samples with a complex composition (such as 
 low-percentage metal oxide nanocomposites\, nanoalloys\, and samples of na
 tural origin) were synthesized and/or selected from existing collections. 
 Test samples and benchmarks necessary for testing and developing SR techni
 ques were studied by a set of methods (μ-XANES/EXAFS\, μ-XRF\, XAFS\, XR
 F\, HRTEM\, XPS\, SEM\, EDX\, etc.). New information about phase and eleme
 nt compositions\, atomic structure\, morphology\, and structural parameter
 s was obtained for the test systems under study. The data obtained by all 
 the methods are in a good agreement. The possibilities of the proposed app
 roach for the study of microparticles and micro-inclusions of complex comp
 osition by methods implemented using synchrotron radiation are demonstrate
 d.\nThe work was carried out in the framework of the RFBR projects no. 19-
 05-50046\, 18-03-01251. The work was done at the shared research center SS
 TRC on the basis of the Novosibirsk FEL/VEPP-4-VEPP-2000 complex at BINP S
 B RAS\, using equipment supported by project RFMEFI62119X0022.\n\nhttps://
