    Participating Countries and International Organizations:
    Belarus, Bulgaria, China, Cuba, Czech Republic, Egypt, Germany, India, Kazakhstan, Moldova, Mongolia, Poland, Romania, Russia, Serbia, Slovak Republic, South Africa, Spain, Ukraine, United Kingdom, USA, Vietnam.
    Scientific Programme:
    Transition to a new level of research and development in the fields of radiation solid state physics, applied radiochemistry and materials science, with a prospect of to nanotechnology applications. The main emphasis will be on the modification of the materials at the nanometer scale and on the study of the effects produced by heavy ions in matter with the aim of revealing the fundamental mechanisms and of the development of nanotechnology applications for ion beams. Modernization of the FLNR facilities for the production of medical isotopes and developement of materials modification methods.

    Expected main results in 2017:

    • Determination of the threshold electronic stopping powers for latent track formation and study of track region morphology in Y-Al, Y-Ti and Ti oxide crystals using high-resolution transmission electron microscopy.

    • Study of structural changes induced by heavy ions of fission fragment energy in oxide and carbide nanoparticles in oxide dispersion-strengthened alloys.
      Registration and measurement of structure characteristics of heavy ion latent tracks in polymers using scanning probe tomography.

    • Study of effects of high-energy ion bombardment in 2D-materials.

    • Study of giant magnetic resistance in metal nanowires obtained using template synthesis in track-etched nanopores.

    • Investigation of osmotic phenomena in nanochannels obtained by the track etching technique. Development of a convection-diffusion model for electrolyte transport in track-etched nanopores.

    • Development of methods for coating track membranes with SERS-active layers aimed at creation of high-sensitivity membrane sensors.

    • Study of mass transport processes under electrical field in hydrophobic nanochannels.

    • Application of the method of recoil nuclei for separation and concentration of radioactive isotopes 99Mo( 99Tc), 225Ac, 236Np, development of synthesis according to reaction (gamma, n) 64Cu, 196Au for nuclear medicine and environmental studies.
