The 37th volume of the Journal of Metastable and Nanocrystalline Materials contains articles that review the photoluminescence and super capacitive properties of carbon dots nanoparticles, bi-functional applications of some nanoparticles and nanocomposites. The results of the controlled synthesis and electrical properties study of semiconductor single crystals are also presented. The application of the maximum entropy method and method of density functional theory for the numerical investigation of the crystalline defects of nanocrystals and optimization calculations on the structure of nanoclusters were also investigated in two of the presented articles. This issue will be helpful to many specialists in applied materials science and nanotechnologies.
