Position: Head of Laboratory
About: Dr. Efimchenko was born in Kirsanov, Russia, in 1982. Graduated in Solid State Physics from the Institute of Physics, Mathematics and Informatics of the Tambov State University in 2004 and entered the Institute of Solid State Physics RAS the same year. In 2008, he defended his Ph.D. thesis on "Phase transformations in the water-hydrogen system at high pressures". Since 2020, Dr. Efimchenko has been Head of the Laboratory of High Pressure Physics at ISSP RAS.
Research activities: Synthesis at high hydrogen pressures and studies of the properties of water hydrates and solid solutions of molecular hydrogen in silica and silicates. In particular, he synthesized a new hydrogen hydrate, the S0 phase, and discovered a high solubility of hydrogen, up to the molecular ratio H2/SiO2 = 0.7, in amorphous quartz.
