Laboratory Staff: 17 employees including 14 researchers, two of them have obtained Habilitation and seven other are PhD holders.


The Laboratory of structural and phase analysis was established in 1974 under the direction of Prof. S. I. Alyamovskii. A large role in the establishing of the lab themes and their further development belongs to Prof. Dr. P. V. Geld, the Corresponding Member of the Russian Academy of Sciences and the Head of the Department of general physics at the Ural Polytechnic Institute. Prof. Dr. Geld was working for decades in the Institute as a Scientific Advisor. He suggested an idea of advanced neutron diffraction studies, which were systematically developed by Dr. habil. Vladimir G. Zubkov. Since 1976 the Laboratory has been engaged in the studies in high pressure chemistry, in particular, the evolution of structural vacancies in variable-composition phases exposed to high pressures. Later, when relevant equipment became available, scanning electron microscopy and tunneling microscopy methods have been developed.

The Laboratory unites the three groups.
