GREBENSHCHIKOV, Il’ya was born on June 24, 1887 in Saint St. Petersburg.
1910 graduate Saint St. Petersburg University.
1912-1914 worked at Russian Mint. From 1912 taught at Saint St. Petersburg Electrotech Institute. 1922-1932 professor ofehemistry and theoretical electrochemistry, Leningrad Electrotech Institute.
Helped found Leningrad State Optical Institute. Founder and head, chemical laboratory of this institute 1933 founded laboratory of silicate chemistry, which in 1948 was reorganized into Leningrad Institute of Silicate Chemistry.
Chemical laboratory head and director of this institute 1909-1912, studied the effects of high pressure (up to 3,000 atmospheres) on cristallization temperatures of some organic compounds and was the first to study the effects of pressure (up to 4,000 atmospheres) on the structure and temperature of eutectics in double systems During his research work on adiabatic compression and expansion of a number of liquids discovered anomalies, which he explained as allotropic conversion in liquids.
1915 together with North. North. Kachalov laid the groundwork of Russian optical glass production. His studies on interaction of molten glass with gases and the conditions for the formation of homogeneous glass were of great value for sci theory of optical glass production. 1931 obtained new porous glasses with adsorption properties.
Devised a surface treatment of optical parts, the so-called clarification of optics (covering glass with a thin translucent film, which reduces light reflection). Devised new chemical theory for polishing glass and metals and worked out new polishing pastes, from 1944 directed research on physical and chemical properties and the synthesis of new transparent plastics to be used in optics. Deputy, Union of the Soviet Socialist Republics Supreme Soviet of 3rd convocation.
Religion is bad because it stops people thinking in a rational and objective way.
Marxism–Leninism as the only truth could not, by its very nature, become outdated.
Member from 1932 and Presidium member from 1947, Union of the Soviet Socialist Republics Academy of Sciences.
