    Year 2016

    Radiation Effects and Physical Basis of Nanotechnology, Radioanalytical and Radioisotope Investigations at the FLNR Accelerators

    Leaders:   S.N. Dmitriev
    P.Yu. Apel

    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:
    Study of the effects produced by heavy ions in matter for potential applications of ion beams in nanoscience and nanotechnology. Work related to life sciences: production of ultrapure isotopes and study of the properties of radionuclides of practical importance. Upgrade of the FLNR accelerator complex to produce medical isotopes and develop methods of material modification.

    Expected main results in 2016:

    • Study of radiation stability of TiNZrN ceramics irradiated with high-energy heavy ions.

    • Estimation of temperature dependence of structural changes induced by heavy ions of fission fragment energy in nanoparticles in ODS (oxide dispersion strengthened) alloys.

    • Influence of synergistic effect of radiation defects and impurities on the development of helium, deuterium, and hydrogen blisters in silicon.

    • Detailed study of the structure of track membranes in the nanometer range using high-resolution scanning electron microscopy.

    • Development of a fabrication method and study of the properties of track membranes with several pore arrays and a selective layer.

    • Study of surface and electric transport properties of composite track membranes with a hydrophobic layer.

    • Methodological developments of synthesis and radiochemical separation of radionuclides which have great potential in nuclear medicine ( 195mPt, 117mSn, 227Th, 225Ac, 213Bi). Radioecological studies (analysis and study of radionuclide distribution in ecosystems).

    • Development of fabrication methods of SERS-active sensors based on immobilization of silver nanoparticles, thermal evaporation of metal and insulator layers on the track membrane surface and investigation of their efficiency.
