The study of the surface layers of bodies in a condensed state of nuclear-physical methods.

1. The development of fundamentals of technology of radiation-chemical synthesis of principally new track polymer proton-conducting membranes for fuel cells.

2. The development of fundamentals and technologies of formation of polymeric nuclear track membrane materials, their practical application, using to implement many of the priority trends of nano-industry.

3. Study of development trends of membrane and electro-membrane separation of solutions , ways of implementation and practical importance of membrane technologies in various fields of human activities.

4. Study of surface and subsurface layers of solids in the condensed state with the use of nuclear-physical methods of analysis : Method Rutherford ion backscattering , resonant backscatter method, the method of recoil nuclei(nuclear weapons).

RESEARCH RESULTS

These methods allow non-destructive analysis of the elemental composition and structure of the sample surface region. His makes them indispensable in solving a number of practical problems related to modification of the properties of solids in the surface region, for example, in the study of the distribution profiles of impurities in semiconductor materials, with different coatings in machine building, aviation, space sectors, criminology, and art history.

The development of fundamental and applied scientific researches in area of creation of principally new track membrane materials for fuel cells, nuclear track membrane materials with nanostructured surface resistant to aggressive chemical attack. The diameter of the resulting pores depend on energy and type of particles of the material of the irradiated film and the conditions subsequent chemical processing of the irradiated samples. Changing these settings allows you to track membrane is in a range of diameters from 20 nm to several microns, and pore size can be controlled with high accuracy. The advantage of nuclear track technology is able to specify the pore size, configuration and number of pores per square centimeter. Track membranes from polyethylene terephthalate tested for strength, permeability, uniform distribution of pores. Work on the study and forming track etched membranes are marked with diplomas of various exhibitions.
