COMS

The first is DSS = Diffusion, stress, segregation-community gathered by Boris Bokstein (National Technical University ?Institute of Steel and Alloys?, Moscow) and Deszo Beke (University of Debrecen, Hungary). The workshops of this Community have been held in Hungary and Russia since 1995. The last one was in Moscow in June 2010. Usually such workshops gathered about 50 actively working researchers and provided extended possibilities for less formal talks and discussions. At the last meeting in Moscow (2010) it was decided that Cherkasy team would try to organize the next DSS using experience and advices of prof. Bokstein and prof. Beke.

The second is DIFTRANS= Diffusion and diffusional phase TRANSformations. Cherkasy team, together with Kiev researchers from Institute of Metal Physics (NASU), Institute of Physics (NASU), Kiev Polytechnic Institute, organize series of conferences DIFTRANS in Cherkasy region, Ukraine, in 1998, 2001, 2004, 2007.

These workshops, though diffusion ? based, have been concentrated more on diffusion ? controlled solid state reactions. They attracted such bright personalities (known as state-of-art researchers in diffusion and reactions) as Francois d?Heurle, Jean Philibert, King-Ning Tu, Frans Van Loo, Patrick Gas, Vitaliy Slezov, Anton Naumovets, Katayun Barmak, Leonid Klinger, Guido Schmitz, Figiri Hodaj... Thus, alternative abbreviation expansion of DSSR is Diffusion-controlled Solid State Reactions.

DSS and DIFTRANS communities overlap partially. Actually, for DSSR we would like to attract at least several researchers from another, third community ? the nucleation one ? the annual workshops at Joint Institute of Nuclear Research in Dubna, Moscow region, Russia, organized by Dr. Juern Schmelzer ( Rostock, Germany). Such triple joint will help to concentrate on nano-issues of DSSR.

We hope that interdiffusion of ideas from the three abovementioned communities will be truly reactive and productive.
