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 dynamically controlled electrophysical characteristics interacting effectively with electromagnetic radiation high-frequency diapason: polychlorotrifluoroethylene, containing highly disperseoxides (SiO2, TiO2, SnO2, Al2O3) modified with substances having electron-ion conductivities (AgI, CuI, KH2PO4, Ag2S, CdS, CuS). Nanowires CdS with a diameter of 7 nm and a length of more than 200 nm and “core–shell” semiconductor nanocrystals was produced by the developed technique. 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 has been 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.
