Information

Research is under way at present into the behaviour of fluctuations of the order parameter in the critical region of solutions with usual and double critical points; propagation of ultra- and hypersound in viscous media with nonlocal relaxation and in media with developed fluctuations, including close to the critical points of solutions, the rotary motion of molecules in such media.

Peculiarities of stimulated light scattering are studied.

Light scattering on particles of micro- and nanoemulsions,  including in turbid emulsions, of the type of milk, is studied; the behaviour of the size of particles under the action of various physical factors. The use of a lightguide probe for correlation spectroscopy is studied. 

Kinetics of the biophysical processes and the effect of permeability of cytoplasmic membranes on vital processes of cells are studied.

1. Kinetics of oxygen exchange of erythrocytes in vivo and in vitro, change of the state of erythrocytes in preservation of blood for transfusion and in depreservation.

2. Effect of excessive external pressure on the nonspecific permeability of cytoplasmic membranes.

3. Kinetics of redox processes in cells, as the result of which ATP is synthesized, and the kinetics of the consumption processes of this macroerg for the specialized function and other needs in the norm and in pathology (including in carcinogenesis) and the coordination of these processes.
