Laboratory for Chemical Physics of f-elements

Scientific results:

1. During the existence of the Laboratory, we used a laboratory X-ray spectrometer to conduct a series of works to research various materials containing f-elements. We have also conducted research of materials based on d-elements using X-ray absorption spectroscopy (XAS). As an X-ray radiation source we used an X-ray tube with a silver anode with a power output of 1,5 kW. The X-ray tube, the crystal-monochronometor and silicon drift detector (Amptek) were placed in a Rowland circle with a diameter of 0,5. On the basis of the collected data we published articles in highly-ranked journals, and more works are currently being prepared.
2. We have researched a wide range of objects closely related to radioactive waste processing and the behavior of radionuclides in the environment. Thanks to the use of the most advanced synchrotron methods, we have obtained unique data on the local and electron structures of these of these compounds.
3. Our researchers have developed new methods for the modeling of various XAS spectra with the use of different approaches combined semi-empirical methods, quantum mechanics and machine learning. 

Education and career development:

• Employees of the Laboratory organized the school «XAS/XES School 2021 on Advanced Synchrotron Methods: Xray Absorption and Emission spectroscopy» (2-4 June 2021, Department of Radiochemistry of the Faculty of Chemistry of Moscow State University).
• Two Candidate of Sciences dissertations have been prepared and defended.
• Members of the academic staff have developed lecture courses for undergraduate and postgraduate students of the Faculty of Chemistry of Moscow State University (delivered in 2020-2021): «High-resolution synchrotron-based spectroscopy methods: experiment and theory», «Current problems of chemistry: modern physico-chemical methods in radiochemistry and more», «X-ray absorption spectroscopy: experiment, theory, analysis and data processing».
