"Kinetics of irreversible processes in partially ordered structures"
Tropin T.V. (FLNP JINR)
The results of research and descriptions of two characteristic processes, relevant for the advanced condensed matter physics: glass-transition and aggregation of nanoparticles are presented. Experimental research of solutions of fullerenes of various polarity with a set of complementary methods was performed, which allowed to investigate both the structure of the formed clusters and the kinetics of their increase, a number of other phenomena. A theoretical description of kinetic processes in fullerene solutions is presented. Furtherly, description of the polystyrene glass-transition kinetics in a wide range of cooling and heating rates q is discussed. A general theoretical research of the glass-transition of model system in a wide range of velocities q was performed, dependences of the main characteristics of the current process on temperature and pressure variation rates were studied. Finally, glass-transition and the features of the structural organization of nanoparticles in thin films of polymer fullerene-polystyrene nanocomposites are studied using the reflectometry method. (According to the materials of the doctoral dissertation. Specialty 01.04.07 - Condensed matter physics).
