The paper examines the influence of loading modes on polyurethane foam elements on the change in mechanical properties of the material under load, resulting in plastic deformation of the material. Studies were carried out on polyurethane foam samples with different ratios of polyol and isocyanate in the foam-forming mixture. From the materials obta...

The research is devoted to solving the problem of regulating the porosity parameters during the manufacturing process under magnetic field conditions. The process of synthesizing magnetic nanocomponents based on a mixture of divalent and trivalent iron oxides was given. The use of nanocomponents allowed for improving the conditions for creating por...

Rare earth metals REE is vital to modern technology and society and are among the most critical elements. The general physical properties of REE, the history of their discovery, the main natural resources and general applications are highlighted. The criteria by which REE belong to critical raw materials (deficit risk factor, economic importance) a...

A study of the electron-hole conductivity in PbI2 single crystals doped with Hf (0.2 wt %) was conducted using the Wagner polarization cell method. The influence of the Hf alloying admixture (0.2 mass%) on the nature and parameters of lead diiodide’s electronic conductivity has been analyzed. Basing on the received current-potential dependences, p...

RESEARCH OF SURFACE AND VOLUME ELECTRICAL CONDUCTIVITY OF DETECTOR PbI2 STRUCTURES The article is devoted to the study of electrical conductivity of detector PbI2 structures made by machining, taking into account the surface phenomena that arise when applying a constant electric field. The prerequisites for the passage of electric current not only...

The research of the influence of technological modes has been carried out and the negative influence of contaminating impurities on the lead iodide crystallization process has been grounded. The new technological approach to PbI 2 single crystals growth has been proposed, which, unlike traditional methods, is based on increasing of the purity of th...
