The focus will be on several types of environments. These are two-dimensional nanomaterials and layered systems based on them, media with defective structure of point and complex defects, nanofluids, and nanoparticles with defective structure popup.description2 A comprehensive study of the fundamental patterns that appear in nanostructured systems and environments has been performed. The main focus is on three areas. This involves investigation the properties of the nanoobjects themselves, such as complex defects in traditional media, nanoparticles and nanoparticles with a defective structure. Secondly, the properties of two-dimensional nanomaterials and layered systems were investigated. The third directions deals with the properties of nanoparticles of various types-nanoliquids. Within the first direction or researches the influence of sintering dopants on the structure defects in transparent ceramics of yttrium-aluminum garnets was found. The concentrations of complex and simple defects that influence the ceramics quality have been found. The impact of growth conditions onto the defect concentration was established. The conditions were found under which the concentration of defects can be changed by several orders of magnitude. The results obtained allow one control directly the properties of ceramics. The influence of restriction of the freedom degrees on the properties of nanoobjects and the transition to macroscopic properties with an increase of the number of freedom degrees was investigated. A new mechanism of relaxation of nanoparticles with an intrinsic pore has been discovered. Within the second direction, the mechanisms of supersolid state formation in various physical systems has been investigated. The peculiarities of the formation of supersolids in quantum crystals with dislocations, in Bose condensate of dipole molecules, and in two-layer systems with opposite types of conductivity in adjacent layers were examined. The conditions of supersolid state formation were found. The theory of the emergence of through-layer phase during layer-up to layer material growth has been proposed. The mechanism of formation of the domain structure on biological membranes as a result of dopant absorption has been identified. Product Description popup.authors BEZRUK Yurii R. BRODSKYi Roman Ye.
