"Silicate glass is one of the most important and widely spread technical materials. It is frequently used in the applications where it is exposed to the particle radiations of different energies. Therefore, it is very important to study the changes in glass caused by the radiation both from technical applications point of view (changes in glass properties) as well as from point of view of glass science (changes in glass structure).The project will perform a systematic investigation of changes in glass structure and properties caused by electrons irradiation in different energy ranges from about 3\u00A0keV up to MeV\u2019s and by proton irradiation (MeV). The compositional changes and inhomogeneities on the micron scale will be characterized by EPMA. Evolution of structural changes will be studied by XPS, NMR, and Raman spectroscopy. Surface topographies will be characterized by AFM and SEM. Moreover, the molecular dynamics simulations will be used as a theoretical tool for the interpretation of the experimental findings. Chemical durability of glass irradiated with electrons/protons will be established and nanoindentation methods will be used for the characterization of mechanical properties. Expected results may enhance the applicability of glass and improve its limiting properties."@en . "7"^^ .
