The Center for shared use of scientific equipment (CSU) was organized at the Institute of Geological Sciences in December, 2006. It is hosted by the Laboratory of physical methods of research.

Equipment available at the CSU:

- scanning electron microscope (SEM JSM-6490-LV, JEOL, Japan) with an integrated system of electron-probe analysis INCA Energy+ using energy and wave dispersion spectrometers (EDS+WDS, OXFORD, Great Britain) and detector HKL-Channel (OXFORD) (Fig.);

- laser sedimentograph (Mastersizer-2000, Malvern, Great Britain);

- a set of auxiliary equipment and devices for sample preparation.

The principal research area of the CSU is the development and application of techniques to study geological and other specimens using modern equipment for the determination of their composition and morphological features with a view to solving fundamental and applied tasks of geology, lithology, engineering geology, mineralogy, paleontology, and other sciences.

A number of techniques has been developed and used in the Center, in particular:

- a technique for studies of paleontological objects using electron microscopy and X-ray microanalysis;

- a technique of the integral use of the lab equipment for granulometric and engineering geology studies;

- integrated techniques for determining quantitative characteristics of the element composition of geological formations for WDS+EDS INCA Energy+ and investigating some types of geological samples using the system of crystallographic orientation;

- special techniques of X-ray microanalysis for studying thermally unstable samples; methods to register elements that are spatially unstable under electron beam in crystalline and amorphous structures;

- a technique for interpreting the results of electron microscopic studies (morphology, macro- and microcomponent composition) of clayey minerals and pore space structure for terrigenous and terrigenous-chemogenous rocks in conjunction with the results of X-ray structural, spectral and granulometric analyses; it is used to recognize the lateral and vertical zonality of catagenetic transformations in various sections of sedimentary basins for forecasting changes in their filtration capacity;

- a special technique to investigate the nanomorphology and chemical composition of novel high-technology materials for hydrogen energy and space industries.

Since 2007, the CSU employees have defended one candidate and one doctoral thesis, published 45 papers and over 25 abstracts in professional editions. The techniques developed have been implemented in budget-financed studies under NAS target research programs "Strategic mineral resources of Ukraine", "Integrated assessment of the state and forecasts of changes of the marine environment dynamics in the Azov – Black Sea basin" etc.

 

SCU’s equipment has been used to provide services to a number of institutions operating under the NAS of Ukraine, Ministry of Education and Science, the National Academy of Medical Sciences and the International Scientific and Technical Center for Useful Space Loads (Mytishchi, Moscow region).
