Oleg Alexeyevich Jessin

from Wikipedia, the free encyclopedia

Oleg Alexejewitsch Jessin ( Russian Олег Алексеевич Есин ; * 7 September July / 20 September  1904 greg. In Yekaterinburg ; † 13 August 1979 in Sverdlovsk ) was a Russian chemist , physical chemist , metallurgist and university professor .

Life

Jessin's father died in 1909. Jessin began to work when he was thirteen. After attending RabFak , he began studying at the Urals Polytechnic Institute (UPI) in 1920, graduating in 1925 as an electrochemist . The three-year aspiration followed . In 1929 he was sent to Erich Müller in Dresden . After his return in 1930 he continued to work at the UPI, initially as an assistant and lecturer and from 1934 as a professor at the chair for electrochemical process engineering . He examined the electrolysis processes with regard to the discharge of the ions at the electrodes . With his work on the theory of the electrochemical double layer at the metal - electrolyte boundary, he became known worldwide.

1935–1940 Jessin headed the chair for physical chemistry at the Ural University . Under Jessin's direction, the later Professor BF Markow investigated the adsorption of iodine ions on mercury as a function of the electrolyte concentration as part of his diploma thesis in 1937 . The result of their investigation became known as the Esin-Markov effect at the international electrochemistry conference in Canada .

During the German-Soviet war improved Jessin the production processes in the copper electrolytic refinery in Verkhnyaya Pyshma , solved the problems in the production of copper iron - bimetal for bullet casings and grenades and set the first copper powder production of armored - and aircraft engines in the USSR one.

From 1943 Jessin headed the Chair for Theory of Metallurgical Processes at UPI (until 1969). In 1949 he founded the Laboratory for Physical Chemistry of Metallurgical Smelts in the Institute of Chemistry and Metallurgy of the Urals Department of the Academy of Sciences of the USSR , which he headed until 1971 and was then its advisor. In 1953 he became a doctor of technical sciences . In 1961 he set up physicochemical investigations of metallurgical processes as a new discipline at UPI.
