The Russian security services are investigating a well-known Siberian physical chemist on suspicion of divulging state secrets. Oleg P. Korobeinichev, 65, who heads a research laboratory at the Institute of Chemical Kinetics and Combustion in Novosibirsk, has not been formally charged, but he has been ordered not to leave the country. Neither the government nor Korobeinichev is commenting on the case.
Korobeinichev's lab specializes in the structure of flames of gaseous and condensed systems, work that has had applications to the weapons and space industries. Its more recent efforts to develop technology for the disposal of chemical weapons involve collaborations with Cornell University, Sandia National Laboratories, and the National Institute of Standards and Technology, according to its Web site.
