Аннотация: Magnetic and optical properties of GdFe3-xGax(BO3)(4) single crystals are investigated by Mossbauer and optical spectroscopy. The GdFe3(BO3)(4) multielectron band structure model is derived. A high- and low-spin crossover of Fe3+ ion, a collapse of the magnetic moment, the suppression of Coulomb correlations, and insulator-semiconductor transition are predicted. The jump of an energy gap is measured at pressure 43 GPa. (c) 2005 Elsevier B.V. All rights reserved.

Аннотация: Hydrogen sorption by various carbonaceous products formed during arc discharge in carbon-helium plasma has been studied. The main product fractions included a fullerene-containing soot, a fullerene mixture extract, a condensate containing carbon nanotubes, and carbonized aluminum oxide. Molecular hydrogen is most effectively sorbed by single-wall carbon nanotubes contained in the carbon condensate fraction. (C) 2005 Pleiades Publishing, Inc.

Аннотация: Uniaxially oriented films of polymer-encapsulated liquid crystals (PELCs) possess strong light-scattering anisotropy. The macroscopic transmittance anisotropy in uniaxially oriented PELC films can be strengthened by adding dichroic dyes to the LC drops. The ratio T-perpendicular to/T-parallel to of the principal components of the optical transmittance polarized perpendicular and parallel to the orientation of the PELCs, respectively, has been measured for He-Ne laser radiation transmitted through uniaxially oriented samples. The experiments showed that the transmittance anisotropy T-perpendicular to/T-parallel to for samples doped with dye is greater than the anisotropy caused only by light scattering.

Аннотация: The mechanisms of inelastic scattering of low-energy protons with a kinetic energy of 2-7 eV by C6H6, C6F12, C-60, and C60F48 molecules are studied using the methods of quantum chemistry and nonempirical molecular dynamics. It is shown that, for the C6H6 + proton and C-60 + proton systems, starting from a distance of 6 angstrom from the carbon skeleton, the electronic charge transfer from the aromatic molecule to H+ occurs with a probability close to unity and transforms the H+ ion into a hydrogen atom and the neutral C6H6 and C-60 molecules into cation radicals. The mechanism of interaction of low-energy protons with C6F12 and C60F48 molecules has a substantially different character and can be considered qualitatively as the interaction between a neutral molecule and a point charge. The Coulomb perturbation of the system arising from the interaction of the noncompensated proton charge with the Mulliken charges of fluorine atoms results in an inversion of the energies of the electronic states localized, on the one hand, on the positively charged hydrogen ion and, on the other hand, on the C6F12 and C60F48 molecules. As a result, the neutral molecule + proton state becomes the ground state. In turn, this inversion makes the electronic charge transfer energetically unfavorable. Quantum-chemical and molecular-dynamics calculations on different levels of theory showed that, for fluorine derivatives of some aromatic structures (C6F12, C60F48), the barriers to proton penetration through carbon hexagons are two to four times lower than for the corresponding parent systems (C6H6, C-60). This effect is explained by the absence of active pi-electrons in the case of fluorinated molecules.

Аннотация: Composite nanoparticles consisting of magnesium, nickel, and carbon atoms are studied both theoretically and experimentally. The calculations performed in terms of the density functional theory show that the jump frequency of hydrogen atoms in nickel-containing magnesium hydride increases substantially near impurity nickel atoms; as a result, the rate of hydrogen absorption by magnesium also increases. Nickel on the magnesium surface is shown to be absorbed via an island growth mechanism. Composite Mg-C, Ni-C, and Mg-Ni-C powders are produced by plasmachemical synthesis in a carbon-helium plasma stream. Hydrogen is introduced into a chamber during synthesis. It is found by X-ray photoelectron spectroscopy and thermogravimetric analysis that, among these three composites, only Mg-Ni-C contains magnesium fixed in the MgH2 compound. The process of such "ultrarapid" hydrogenation of magnesium, which occurs in the time of formation of composite nanoparticles, can be explained by the catalytic action of nickel, which is enhanced by a high temperature. Scanning electron microscopy micrographs demonstrate the dynamics of the dehydrogenation of Mg-Ni-C composite nanoparticles in heating by an electron beam.

    Synthesis of fullerenes in a high-frequency arc plasma under elevated helium pressure / Г. Н. Чурилов, W. Krätschmer [et al.] // Carbon. - 2013. - Vol. 62. - P. 389-392DOI 10.1016/j.carbon.2013.06.022
   Перевод заглавия: Синтез фуллеренов в высокочастотной дуговой плазме при повышенном давлении гелия
Аннотация: We show that in a carbon–helium high-frequency (66 kHz) arc discharge the fullerene yield and composition can be controlled by changing the helium pressure. By emission spectroscopy we could derive the excitation temperature within the arc. We found that the radial temperature gradient of the arc plasma increases with increasing pressure. We further found that with increasing pressure the yield of fullerenes reaches a maximum of 12.6 wt.% at 0.12 MPa pressure and in the range from 0.16 to 0.38 MPa the fullerene content in the carbon soot stays within the limits of 7.2–7.0 wt.%. The content of С70 and higher fullerenes relative to the total amount of extractable fullerenes increases with pressure. Our results suggest that in the carbon–helium plasma fullerenes are mainly formed in a top-down process by the decay and annealing of large, hot precursor carbon molecules.
