Karazin popup.description2 The objects investigated - metals (copper, aluminium, tin, germanium, niobium, potassium) and alloys, aqueous and aqueous-organic solutions.The aim of the work - investigation of physico-chemical regularities of metal ionization and electrocrystallization in aqueous and aqueous-organic solutions and the elaboration of conditions of semi- and superconductive layers with goal properties formation; associate formation in aqueous solutions study; interparticle interaction investigation and dissociation thermodynamic function calculation in amino acids, their salts and derivatives solutions.The results of chemical and electrochemical processes on copper in ammonia contained solutions investigation have been presented. The polylayer surface film contained CuCl, Cu2O, Cu2(OH)3Cl has been shown to be form by copper passivation. It has been established, that electrochemically formated films more dense, less soluble and reactive, as chemically formated by interaction with solution components. Adhesion on coppersurface and anodic formated surface compaction increase with anode potential and it scanning velocity increase, amonia and chloride concentration in solution enlargement. The composition of aluminium alloys effect on it electrochemical behaviour has been investigated. Aluminium and it alloys corrosion follows with electrochemical mechanism with cathodic control. The most destructive effect has been established to provide the copper additives. The data due to temperature effect on phase division border at aluminium and it alloys oxidation in solutions with different composition have been obtained. The surfactant additives in the solutions of tin and copper chemical reduction on dielectrics has been shown to be adsorb on the catalytic surface and promote the dense adsorb layer, that blocks oxidation-reduction reaction of chemical reduction. In contact exchange systems the surfactant impurities catalyze the process of chemical plating. The physical model of system chemical reduction and contact metal exchange inhydrodynamic mass-carrying regime has been proposed, the boundary conditions of the model satisfiability have been established. The comparative analysis of kinetic, physical and hydrodynamic parameter change for these systems depending on cylindric sample rotation velocity has been provided. The copper complex formation in nitrate contained systems has been investigated by spectrophotometric method. Modification capacity of additives investigated has been shown to be stipulate by their capacity to bind copper ions in strong complexes with cyclic groups formation. On the basis of analytical and numerical approaches the energetic spectra and thermodynamic properties of nanosystems with spin transfer have been investigated. The existance of quantum phase transitions of first kind has been shown. The simple formula for the heat capacity approximate evaluation by the lack of low-energy bounded states has been derived. It has been shown about 4 peaks on heat capacity temperature dependence. Based on conductivity data of dilute (1·10-6 - 5·10-2 mol/kg) electrolyte solutions of some sodium salts: NaCl, NaBr, NaI, NaNO3, NaClO4, NaSCN in ethanol in the temperature range 213.15-333.15 K (in 10 K intervals) the standart Gibbs energy, enthalpy and entropy of ion-pair formation as well as contributions of electrostatic interactions to these functions have been calculated.
