The Na2SO4 − Dy samples were obtained by slow evaporation method. The spectroscopic methods were used to study the mechanisms of formation of electron and hole trapping centers. Intrinsic recombination emission of 2.9–3.1 eV and impurity emission of 2.55 eV and 2.15 eV are excited at 4.0–4.5 eV. Intrinsic SO3− 4 − SO− 4 and impurity Dy2+ − SO− 4 trapping centers were ...

Inorganic-based nanoelements such as nanoparticles (nanodots), nanopillars and nanowires, which have at least one dimension of 100 nm or less, have been extensively developed for biomedical applications. Furthermore, their properties can be varied by controlling such parameters as element shape, size, surface functionalization, and mutual interactions. In this study, ...

The effect of microstructure on the efficiency of shielding or shunting of the magnetic flux by permalloy shields was investigated in the present work. For this purpose, the FeNi shielding coatings with different grain structures were obtained using stationary and pulsed electrodeposition. The coatings’ composition, crystal structure, surface microstructure, magnetic domain ...

The paper presents the dependence of the degradation degree in various aggressive media and time in a medium. The greatest deterioration in crystallographic characteristics of nanostructures in corrosive media is observed on the day 10th , which is due to partial destruction of the crystal structure as a result of oxidation processes. Also, an increase in the oxygen concentration ...

Investigation of the Microstructure of Fine-Grained YPO4:Gd Ceramics with Xenotime Structure after Xe Irradiation. Ceramics 2022, 5, 237–252. https://doi.org/10.3390/ ceramics5020019

The paper presents the results of a study of the effect of irradiation with heavy Xe22+ ions with an energy of 440 keV and irradiation fluences of 1014, 5x1014, 1015 ion/cm 2 on the properties of ceramics based on silicon carbide (SiC). The choice of the type of irradiation and dose load is due to the possibility of modeling radiation damage to the surface layer with a ...

Interpolymer complexes based on cellulose ethers have gained significant interest in recent years due to their versatile applications. These complexes are formed by combining different polymers through non-covalent interactions, resulting in stable structures. This article provides an overview of the various fields where IPCs based on cellulose ethers find application. IPCs ...
