The aim is to establish the regularities of structure formation and phase transformations in nanodisperse systems, spin-crossover compounds and spectra of quasiparticles in semiconductor nanofilms; establishment of features, possibilities of control and estimation of deformation and durability of biotechnical systems, substantiation of constructive decisions for creation of their functional analogues - metal-polymeric designs; finding ways to introduce the latest technologies in the process of training specialists in higher professional and technological education. Methods - modeling the processes of formation of new phase nanoparticles at the stage of the Ostwald ripening; the influence of external factors and internal interactions on the states of electronic and phonon systems in nanohetero- and spin-crossover structures; the effect of random loads on the strength of metal-polymer fixing structures for osteosynthesis of tubular bones. Methods of quantum solid state theory and statistical physics are used too. For the first time, size distribution functions, time dependences of reaching critical and maximum sizes, and other growth characteristics of catalytic nanoparticles and single-layer carbon nanotubes in the processes of their Ostwald ripening have been established. The interaction of carriers with optical and acoustic phonons in semiconductor nanofilms and spin-crossovers has been studied. For the first time the influences of spatial constraints and external factors on the states and absorption spectra of such systems are analyzed, the conditions of realization of the phenomenon of optical bistability in them are determined. Firstly the impact on the strength of the fixing structure of osteosynthesis of the type of its cross section, size, number and location of mounting screws in it.
