E.N. Korchagina was born in Leningrad to a family of geophysicists in 1950. After graduating from high school with honors, she unexpectedly entered the M.I. Kalinin Leningrad Polytechnic Institute in 1967, studying in the Department of Aerothermodynamics, Faculty of Physics and Mechanics. While working on her thesis, she gave birth to her first son, but this did not prevent her from defending her thesis on time. Her first job after graduating in 1973 was at the Galurgy Research Institute, where she worked first as an engineer and then as a junior researcher. In 1981, she defended her dissertation for the degree of Candidate of Technical Sciences. In 1987, she entered a competition to work at the D.I. Mendeleev All-Union Research Institute of Metrology as a senior researcher and custodian of the state primary standard of the unit of combustion energy (GET 16-78). Since then, all her energy, creativity, and passion have been connected with this standard and combustion calorimetry. She has developed numerous regulatory documents (GOSTs, methods, and recommendations on metrology), published over 70 articles, developed a large set of standard samples for bomb and gas calorimetry, and is a long-time organizer of seminars and advanced training courses on “Combustion Calorimetry and Measurement of Fuel Quality Parameters.” In 2004, she was appointed head of the Laboratory of Calorimetry and High-Purity Substances for Metrology Purposes. Work to improve the standard, which begun in 2007, culminated in the creation of a new-generation standard facility and the approval of the state primary standard for units of combustion energy, specific combustion energy, and volumetric combustion energy (GET 16-2010). In 2012, under her leadership, the state special standard for the unit of heat quantity in solution and reaction calorimetry (GET 133-2012) was reapproved, and she was appointed its custodian. In recent years, both standards have undergone improvement procedures. GET 16 was modernized and approved in a new configuration in 2018 with the addition of two gas calorimeters. In 2023, the laboratory completed a project to improve GET 133, which enabled the implementation of the isothermal titration calorimetry method and expanded the measurement range of the primary special standard GET 133 to include microcalorimetry.

The laboratory is currently implementing projects to create state reference materials for the temperature and heat of fusion of organic substances, expand the range of reference materials for volumetric energy of combustion and Wobbe index, and develop multiparameter reference materials for coal quality parameters.

For over ten years, the laboratory has been providing interlaboratory comparison tests of coal, petroleum products, and natural gas, involving more than 100 laboratories in Russia and neighboring countries.

Under the leadership of E.N. Korchagina, as coordinator, the laboratory organized and successfully conducted a number of international comparisons of national standards within the COOMET and Euromet frameworks, involving China, Turkey, Belarus, France, Germany, and Romania.

A.P. Nemudry, Doctor of Chemical Sciences, Corresponding Member of the Russian Academy of Sciences, Director of the Institute of Solid State Chemistry and Mechanochemistry SB RAS, is a specialist in solid-state chemistry and materials science and the author of over 500 scientific papers, including one monograph, two chapters in monographs, and eight patents.

A.P. Nemudry has made significant contributions to the study of the real structure and reactivity of nonstoichiometric ABO_3-δ perovskites with mixed oxygen and electron conductivity (MOEC). He established the mechanisms of nanostructuring in MOEC oxides by introducing compositional disorder into the oxygen and cation sublattices through a reduction in the size of ferroelastic 90° twins and coherent domain fusion resulting from local ordering in the B sublattice. It was shown that domain walls act as channels for facilitated diffusion of oxygen ions. Based on nanostructured oxides, the following have been developed:

• Materials for oxygen-permeable membranes that can be used in catalytic membrane reactors for hydrocarbon conversion;
• Cathode materials that provide high peak power for microtubular solid oxide fuel cells due to high rates of oxygen exchange with the gas phase.

Under the supervision of A.P. Nemudry, equipment and new relaxation methods for obtaining equilibrium and kinetic data on oxygen exchange for oxides have been developed.

In the kinetics of oxygen exchange between oxides with the gas phase, A.P. Nemudry was the first to propose considering nonstoichiometric oxides as continuous homologues and a methodology for analyzing kinetic data in an isostoichiometric cross-section.

Rusanov and M.M. Shultz, Professors M.P. Susarev, V.T. Zharov, V.K. Filippov, and others.

His research interests encompass a wide range of contemporary problems, from fundamental issues of general, chemical, and nonequilibrium thermodynamics to chemical engineering. Among his key achievements, fundamental results, both theoretical and experimental, in the field of reaction-mass transfer processes and combined processes in chemical engineering are noteworthy. This work required obtaining a large array of experimental data on equilibria and processes in multicomponent systems, analyzing and generalizing the thermodynamic behavior of these systems, and applying principles of thermodynamic stability theory, including studies of critical states in chemically reacting environments. One of the key features of A.M. Toikka’s approach to solving thermodynamic problems, in addition to a thorough analysis of fundamental principles, is the use of the apparatus of nonequilibrium thermodynamics, laws at the atomic and molecular level, and new mathematical methods. He established a new research program at St. Petersburg State University focused on fundamental and applied membrane technology and materials science: the creation and study of polymer and composite membranes for pervaporation and gas separation.

A.M. Toikka’s research results have been published in over 170 papers in high-ranking international journals (according to Scopus and Web of Science 2026), focusing on the thermodynamic stability of complex systems, phase and chemical processes in heterogeneous systems, and critical states. He has supervised nine grants from the Russian Foundation for Basic Research (since 1993), including the international grant from the Russian Foundation for Basic Research (RFBR-Iran) (2017-2020), and four grants supported by the Russian Science Foundation in the fields of membrane processes, critical phenomena in chemically reacting environments, and related problems. Twelve PhD theses and one doctoral dissertation have been defended under A.M. Toikka’s supervision.
