This course offers an elaborated explanation of quite different behavior of nanomaterials (i.e. nanostructured materials and nanocomposites) in comparison with their bulk counterparts. Consistent top-down approach consists in extrapolation of basic physical and chemical principles of "macroword" to "nano" region (1-100 nm) is used for interpretation of size-dependent properties of nanomaterials (density, bulk modulus, heat capacity, heat conductivity, cohesive energy, temperature and enthalpy of melting and solid-state transitions, temperature of magnetic transitions, glass transition, surface and interface energies, diffusion coefficient etc.).
