Аннотация: We consider the problem of determining the parameters for high-T-c superconducting copper oxides. Alternative approaches, the ab initio LDA and LDA + U calculations and the generalized tight-binding (GTB) method for strongly correlated electron systems, are used to calculate hopping and exchange parameters of the effective singlet-triplet model for the CuO2 layer. The resulting parameters are in remarkably good agreement with each other and with parameters extracted from experiment. This set of parameters is proposed for proper quantitative description of the physics of hole-doped high-T-c cuprates in the framework of effective models. (C) 2004 MAIK "Nauka / Interperiodica".

Аннотация: We have experimentally studied the magnetic properties of manganite films obtained for first time using an extraction-pyrolysis technique. It is established that the characteristics of samples significantly depend on the conditions of final annealing. The annealing at temperatures T-a 970 K is accompanied by strong thermomagmetic effects. and the resulting films possess properties similar to those of spin glasses. When the annealig temperature is increased to T-a = 1020 K, the films exhibit magnetic properties typical of ferromagnetic systems.

Аннотация: This work focuses on the sorption recovery of platinum (II, IV) and rhodium (III) simultaneously present in chloride solutions, freshly prepared and stored over 3 months, on commercial anion exchangers with different physical and chemical structure. The sorption was carried out from solutions with 0.001-4.0 mol/L HCl. The initial platinum and rhodium concentrations in contacting solutions were 0.25-2.5 mmol/L Sorption and kinetic properties of the chosen anion exchangers were investigated and the basic parameters of exchange capacity, recovery, distribution coefficients, separation factors, process rate, diffusion coefficients and half-exchange times were calculated. It is shown that anion exchangers investigated possess high sorption ability to platinum and rhodium chloride complexes, which does not deteriorate in case of stored solutions. Desorption of platinum and rhodium from the resins investigated was carried out with hydrochloric acid (2 mol/L), thiourea (1 mol/L) in sulfuric acid (2 mol/L) or in potassium hydroxide (2 mol/L) as well as by ammonium thiocyanate (2 mol/L). It was shown that complete separation of platinum and rhodium can be carried out with 2 mol/L HCl on anion exchanger Purolite S 985, whereas 2 mol/L NH(4)SCN as an elution agent leads to complete separation of noble metals on anion exchangers Purolite S 985, Purolite A 500 and AM-2B.

Аннотация: Regularities of sorption extraction of platinum(II, IV) and rhodium(III) by anion exchangers of various physical and chemical structure in the presence of hydrochloric media were studied. It is established that AM-2B, Purolite A 500, and Purolite S 985 ionites adsorb complex anions of platinum metals employing mixed mechanism. A high affinity of the studied anionites for the studied complex anions of platinum and rhodium is established.

Аннотация: Luminescent Y1.74Eu0.16Bi0.1O3 films have been obtained by extraction pyrolytic method. The formation of a crystalline structure in the film upon isothermal annealing in air at 600–650°C was established by X-ray diffraction. Single-phase Y1.74Eu0.16Bi0.1O3 films begin to exhibit luminescent properties after pyrolysis at 500°C; the intensity of luminescence increases with increasing temperature. The films annealed at 800°C consists of defect-free homogeneous crystallites with sizes of about 0.7 μm and demonstrats high luminescence intensity.

Аннотация: The sorption concentration of platinum(II,IV) in the presence of iron(III) is studied on new samples of domestically produced ionites of the CYBBER brand. In comparing the sorption and kinetic properties of the new ionites to those of sorbents of the Purolite brand studied earlier, the higher effectiveness of the former is demonstrated via the extraction of platinum(II,IV) ions from strongly and weakly acidic chloride solutions. It is found that the sorbed platinum ions can be completely separated from iron(III) ions through separate elution using 0.01-0.001 M HCl (iron ions) and a thiourea solution (80 g/L) in 0.3 M H2SO4 (platinum ions).

Indium-tin oxide -- thin films -- extraction-pyrolysis technique -- liquid precursors -- nanocrystalline structure
Аннотация: Thin films of indium-tin oxide (ITO) have been prepared by pyrolysis of liquid organic-extracts of indium and tin. The films were deposited on glass substrate in the atmospheric condition. Extraction-pyrolytic method adopted here uses cheap starting materials and provides the required stoichiometric ratio by mixing the stable liquid precursors in appropriate concentration. Thermal decomposition processes are induced in the narrow temperature range of 350–400°C. The zirconium-yttrium oxide (ZYO) sublayer was deposited on glass substrate in advance to provide homo epitaxial growth. This would induce reduction in intrinsic stress of the films due to matching in thermal expansion coefficient with ITO film. XPS studies showed the absence of impurity elements in these extraction-pyrolytic technique derived ITO films and the spectra is quite similar to that for ITO films deposited in vacuum environment. ITO film has a nanocrystalline structure with grain size of about 6 nm.

Аннотация: Yttrium-containing endohedral metallofullerenes are synthesized in an RF arc discharge in the helium flow with embedded Y2O3. It is shown that the formation of the metallofullerenes depends on the helium pressure in a chamber; however, this dependence cannot be explained using the model of formation of conventional fullerenes without a guest atom in a molecule. The results of extraction of Y@C-82 by pyridine and carbon disulfide are reported. The pressure corresponding to the maximum yttrium-containing endohedral metallofullerene content is shown to be 60 kPa; under this pressure, extraction by carbon disulfide allows obtaining 27.1 wt % of the endohedral metallofullerene, while extraction by pyridine yields its amount of 17.3 wt %.
