263 NIKITIN 



Neumann's main works deal with investigating phenomena in 

 non-linear electric circuits, the study of the skin-effect in 

 ferromagnetic bodies, the electromagnetic processes in electric 

 systems with powerful ion converting units, and with direct 

 current transmissions. He has participated in the work of the 

 International Electrotechnical Commission in the fields of 

 scientific terminology and of systems of electric and magnetic 

 units.

NIKITIN, NIKOLAI IGNAT'EVICH (Chemist) 



N. L Nikitin was born March 12, 1890. He graduated in 1913 

 from the Institute of Forestry in Petersburg. In 1929 he be- 

 came professor at the S. M. Kirov Leningrad Forest-Technical 

 Academy. He has been a Corresponding Member of the U.S.S.R. 

 Academy of Sciences since 1939 and of the Finnish Chemical 

 Society since 1959. 



Nikitin has worked in cellulose and wood chemistry. He ob- 

 tained new solutions of cellulose derivatives in alkali by weak 

 esterification and freezing, obtained the fibers from the so- 

 lutions of low -substituted xanthogenates and obtained the films 

 of alkali -soluble low -substituted nitrocellulose and carboxy- 

 methylcellulose. He investigated the role of packing of cellu- 

 lose molecules on the lyophilic properties of fibers and their 

 relation to the quantity of nonfreezing water in the fibers. He
