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:
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).

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 %.

Представлены исследования тонких пленок оксида никеля, полученных экстракционно-пиролитическим методом на стеклянных и кварцевых подложках при температурах 380-600 °С. Пленки охарактеризованы методами атомно-силовой микроскопии и рентгеновской дифракции. Показано, что на стекле формируются аморфные, а на кварце - кристаллические пленки оксида никеля. Размер зерна в пленках зависит от температуры отжига, при этом повышенные температуры отжига приводят к рекристаллизации и снижению размера зерна в пленках NiO от 130 до 35 нм.

Аннотация:
Spin accumulation effect in Fe3Si/p-Si structure with low boron doped silicon substrate was found. Calculated spin lifetimes are comparable with results reported earlier but for structures with highly doped semiconductors (SC) with or without a tunnel barrier introduced between the SC and ferromagnet (FM). Electrical characterization of a prepared Fe3Si/p-Si diode allowed the determination of possible reasons for the pronounced spin signal. Analysis of the forward bias I-V curve revealed a Schottky barrier at the Fe3Si/p-Si interface with a height of φBp = 0.57 eV. Then, using impedance spectroscopy, we observed interface states localized in the band gap of silicon with energy of E LS = 40 meV. Such states most probably cause the observed spin signal. We believe that in our experiment, spin-dependent hole
extraction
was performed via the interface states resulting in the minority spin accumulation in the silicon valence band. The observed effect paves the way to the development of different spintronic devices based on FM/SC structures without dielectric tunneling barriers.

Аннотация:
The Soxhlet
extraction
method (SE) only used in the
extraction
of fullerenes from carbon condensate (CC) obtained in the fullerene production facility, which in the literature is often referred to as carbon black, does not provide complete
extraction
. Fullerenes can also be extracted from the CC suspension and the solvent by the mechanical
extraction
method (ME) and show higher degree of
extraction
efficiency. This method combined with filtration process takes only a few minutes and allows a significant reduction in solvent consumption.
Extraction
via the ME method application makes it possible to carry out
extraction
of fullerenes twenty times faster than by the SE method. It can be used as an independent method, bypassing the
extraction
by the SE method, and also as an additional one. Application of the ME method allows additional
extraction
of fullerenes weight percentage from the CC, after extracting fullerenes from it applying the SE method. In this instance the higher fullerenes prevail in the essences extracted by the ME method with their content reaching as high as 39.50 wt%. The obtained samples of fullerene mixtures (FM) are characterized by the methods of high-performance liquid chromatography and mass spectrometry. Analysis of the results shows that the composition of the FM, isolated by the ME method, differs from the compositions extracted via the ME method.

Аннотация:
The paper presents results of fullerenes and endohedral metallofullerenes extracts studies, isolated from the graphite rods carbon soot spray, and containing Y2O3 in a high frequency arc discharge. Two ways of
extraction
were applied and compared–(1) the classic method of Soxhlet
extraction
, and (2) the one developed by our team–
extraction
based on mechanical action combined with filtration. To implement the method, we used a laboratory version of installation, embodying technical solutions for rapid
extraction
. Chromatographic and mass spectrometry studies of fullerene extracts obtained by these methods revealed that by combining mechanical action with simultaneous filtration, we can significantly intensify and reduce the process of extracting fullerenes and endohedral metallofullerenes compared to the Soxhlet
extraction
method. This is especially evident in the release of endohedral metallofullerenes. Our method allows to reduce the release time of fullerenes from 10 g of carbon soot on laboratory installation up to 15 minutes, against the Soxhlet
extraction
method taking 18 hours. Whilst, the total number of fullerenes extracted by both methods almost coincides (the
extraction
method using mechanical action allowed us to extract 0.2-0.4 wt. % more), the composition of the isolated fullerene mixtures is different. The relative content of higher fullerenes and endohedral metallofullerenes exceeds when the mechanical action-based
extraction
method applied. © 2019, © 2019 Taylor & Francis Group, LLC.

Аннотация:
The dispersions of semiconducting (sc-) and metallic (m-) SWCNTs with purity more than 98 and 86%, correspondingly, were obtained by using the aqueous two-phase
extraction
method. The unseparated (un-) SWCNTs contained ~3/4 of semiconducting and ~1/4 of metallic nanotubes. Thin films based on unseparated, semiconducting and metallic SWCNTs were prepared by vacuum filtration method. An Atomic Force Microscopy (AFM) and a Transmission Electronic Microscopy (TEM) were used to investigate the thin film microstructure. The thin SWCNT film transmittance was measured in the wavelength range of 300–1500 nm. Thermoelectric properties were carried out in the temperature range up to 200 °C. The largest Seebeck coefficient was observed for thin films based on semiconducting SWCNTs. The maximum value was 98 μV/K under the temperature of 170 °C. The lowest resistivity was 7.5·10−4·Ohm·cm at room temperature for thin un-SWCNT films. The power factor for m-SWCNT and un-SWCNT films was 47 and 213 μW m−1 K−2, correspondingly, at room temperature and 74 and 54 μW m−1 K−2 at 200 °C, respectively. For a thin sc-SWCNT film the maximum power factor was 2.8 μW m−1 K−2 at 160 °C. The un-SWCNT film thermal conductivity coefficient was 5.63 and 3.64 W m−1 K−1 and a thermoelectric figure of merit was 0.011 and 0.016 at temperatures of 23 and 50 °C, respectively.

Аннотация:
This paper reports studies of thin films of nickel oxide obtained by the extraction–pyrolysis method on glass and quartz substrates at temperatures of 380–600°C. The films have been characterized by atomic force microscopy and X-ray diffraction. It is shown that amorphous and crystalline nickel oxide films are formed on the glass. The grain size depends on the annealing temperature, while increased annealing temperatures lead to recrystallization and a decrease in the grain size in NiO films from 130 to 35 nm.
