DUBININ, MIKHAIL MIKHAILQVICH (Physical Chemist) 



M. M. Dubinin was born December 20, 1900. In 1921 he 

 graduated from a technical institute in Moscow and began teach- 

 ing there. He was a pupil of N. A. Shilov (1872-1930, outstand- 

 ing physical chemist in catalysis and surface adsorption). 

 Dubinin taught at the Military Academy of Chemical Defense in 

 1932 and became a professor there in 1933. From 1946 to 1950 

 he was President of the All-Union D. I. Mendeleev Chemical 

 Society. He was made Chief of the Sorption Processes Labora- 

 tory at the Institute of Physical Chemistry of the U.S.S.R. 

 Academy of Sciences in 1946. Since 1943 he has been an Acade- 

 mician of the U.S.S.R. Academy of Sciences. And from 1948 to 

 1957 he was Secretary -Academician of the Division of Chemical 

 Sciences at the U.S.S.R. Academy of Sciences. In 1942 and in 

 1950 he was awarded Stalin Prizes. In 1961, he was awarded 

 the Red Banner of Labor. 



Since 1925 Dubinin has studied phenomena of absorption of 

 gases, vapors and dissolved substances by porous solids. He 

 proposed new methods of preparation of pure activated char- 

 coal. These samples helped him study adsorption and for- 

 mation of surface oxides of the acid type. They also helped him 

 to develop the basis for charcoal porosity characteristics. 

 Dubinin determined the mechanism of vapor absorption as a 

 function of the porosity factor of the absorbent structure. From 

 1932 to 1935 he investigated gas and vapor absorption from an 

 air stream which passes through a bed of granular absorbent. 

 He also developed basic concepts of vapor mixture absorption 

 and devised methods and designed equipment for vapor mixture 

 separation. In 1936 and 1937 he studied the effect of absorbent 

 ultraporosity on vapor absorption of substances with different 

 molecule sizes. Since 1940 Dubinin has worked on scientific 

 and practical problems of chemical defense. Since 1946 Dubinin 

 and his co-workers have been successfully investigating the de- 

 pendence of sorption qualities of activated charcoals on their 

 structure and of vapor absorptivity on its physical properties. 

 Dubinin and his associates classified structural types of ab- 

 sorbents. 



As of 1961, Dubinin was a Member of the Presidium of the 

 U.S.S.R. Academy of Sciences. 



Dubinin has attended the Pugwash Conferences.
