Directions of investigations

  • electrophysics of nanostructural composites based on polymers, ferroelectric and substance with of metal-semiconductor, dielectric-superionik phase transitions etc;
  • interaction of electromagnetic radiation with heterogeneous, superdispersed and nanostructured systems;
  • effects of low-intensity electromagnetic radiation on the activity of the processes in biological systems;

 

Main results for the recent years

New nanocomposites have been developed that effectively interacts with electromagnetic radiation of the microwave range, containing nanosized ferrites (BaFe12O19, CaFe2O4, NiFe2O4, СоFe2O4), modified by electrically conductive substances (CuI, CuS, carbon nanotubes), as well as ultradispersed particles (TiO2, BaTiO3, carbon nanotubes, graphene nanoplates) are modified by nanosized particles of metals (NiCo).

It has been established that the formation of percolation electrically conductive clusters on surface electrical structures provide the effective interaction of electromagnetic radiation with such nanocomposites and provide the balance of dielectric and magnetic parameters with the impedance of environment. The results can be the basis for a new conductive composite materials shielding and absorbing electromagnetic radiation, catalysts, etc.

Additional mechanisms of dissipation of electromagnetic energy in the microwave range of systems polymer-conductor have been shown to be connected with polarization effects arising due to interphase interaction of the components. An increase in the values of complex permittivity as well as an expansion of the diapason of their controlled changes is achieved by chemical modifying of surface of polymer with substances having electron-ion conductivities.

When examining the interaction between low-intensive electromagnetic radiation within the millimeter diapason and highly organized systems, a frequency-selective response of biosystems was found. Stimulation of vital activity of yeast cells (Saccharomyces cerevisiae) of suspension was observed for frequencies 40, 47.5, 55, 62.5, 70 GHz and between the values of these frequencies was occurs inactivation of vital activity. Presence of high silica in yeast of suspensions can compensate inhibition of their metabolic processes and increase the bioavailability of nutrients was found.

In the frequency range 47-67 GHz was detected frequency-selective response of blood cell in vitro (including red blood cells), and enzymes. Probably increase blood antioxidant status and occurrence of radical and peroxide conditions is due to mechanisms that are implemented through primary type of catalytic reactions that occur in lipids on the cell surface.

The study of biophysical processes and mechanisms of low-intensity electromagnetic radiation and highly dispersed oxides makes it possible to design controls of vital processes of biological systems and provide system protection from exogenous exposure.

The effect of different dispersity copper iodide particles on vital activity in an aqueous yeast suspension of organisms of the species Saccharomyces cerevisiae under anaerobic conditions under endogenous metabolism was studied by differential microcalorimetry. The occurrence of the stage of activation of defense mechanisms by yeast cells (adaptive cell functions) in the presence of micron and fine particles of copper iodide was revealed in the thermal process. Studies indicate the possibility of a controlled influence on the enzymatic process of yeast cells to activate or inhibit fermentation, depending on the concentration of copper iodide particles in the suspension.
