Beketov national university of urban economy in Kharkiv popup.description2 In the work, research was carried out on the directed modification of serial LFMs with various target impurities. Modification of paint materials with nanoparticles of layered aluminosilicates, carbon nanotubes, detonation nanodiamonds, which allows to improve the physical and mechanical properties of materials and coatings. It is shown that the modification of mesh polymers with reactive oligomers makes it possible to regulate the damping properties of the compositions in a specific temperature-frequency range. Therefore, the creation of vibration-absorbing polymer building materials and coatings based on oligomer-oligomer bonds is a promising direction.Quantum-chemical calculations of complexation energies of iminodiacetic acid with cations of monovalent and divalent metals were carried out. The energies were calculated by the RHF method in the 6-31G(d,p) basis taking into account the MP2 correlation. According to the results of the calculation, a scheme of acid-base interaction in aqueous solutions of iminodiacetic acid was drawn up. It was determined that the main reasons for the rapid corrosion of pumps under conditions of micro-impact impact are a number of factors, the most important of which are low corrosion resistance of the material, hydroerosion, formation of cavitation, high aggressiveness of the environment (significant amount of suspended particles and high oxygen content). The processes of sorption of copper ions by potassium humate from sulfate solutions were investigated. It is shown that in these solutions, the sorption equilibrium is established within one hour of contact of the sorbent with the electrolyte. Electrolysis allows for the recovery of copper ions and obtaining the metal in the form of a cathode deposit, which consists of dendritic crystals. Product Description popup.authors Hurina Halyna І.
