Within the framework of this projects, the problem of one-stage radiation-chemical synthesis of promising hybrid nanomaterials, which may be of potential interest for various applications (creation of tissues with bactericidal properties, sensors, optical filters, catalysts), is being solved. The main attention is paid to the development of new principles for controlling the size and distribution of metallic and bimetallic nanoparticles obtained by radiation induced reduction of metal ions in water-polymer systems. The research uses modern structural methods (electron microscopy, X-ray diffraction analysis), as well as methods for studying the kinetics of radiation-chemical processes (electron absorption spectroscopy and EPR).
