Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ПЕРОВСКИТОПОДОБНЫЕ ФАЗЫ -- ФОТОЭЛЕКТРОННАЯ СПЕКТРОСКОПИЯ -- ВАНАДИЙ Аннотация: We report the first synthesis, at high pressure and temperature (p= 6.0–8.0 GPa, t= 1000°C), of SrxCu3V4O12(x= 0.67–1.0), a cation-deficient perovskite-like phase of variable composition (sp. gr.Im, Z= 2). Using x-ray photoelectron spectroscopy, we have determined the binding energies and valence states of atoms in SrxCu3V4O12. The stoichiometric composition of this phase can be represented by the chemical formula Sr2+Cu2+(V2(5+) V2(4+) )O12. Air exposure leads to the formation of SrCO3 and Sr(OH)2 on its surface and to the oxidation of univalent copper and tetravalent vanadium. According to IR spectroscopy data, the penta- and tetravalent vanadium in the high-pressure phase is in octahedral oxygen coordination. The electrical conductivity, magnetic susceptibility, thermal properties, and ion selectivity of this compound have been investigated Полный текст |

The alloys were found to consist of three phases: refractory phase, TiNi, and delta-Ni2V3 or NbzNi.

The phase composition of the cermets is shown to correlate with the Gibbs energies of formation of the constituent carbides Полный текст |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): СВЕРХПРОВОДИМОСТЬ -- ДИБОРИД МАГНИЯ Аннотация: The effect of disorder induced by neutron irradiation in a nuclear reactor (thermal neutron fluence 1x 10(19) cm–2) on the superconducting transition temperature Tc and the upper critical field Hc2 of polycrystalline MgB2 samples was investigated. Despite the appreciable radiation-induced distortions (more than ten displacements per atom), the initial crystal structure (C32) was retained. The temperature Tc decreased from 38 to 5 K upon irradiation and was practically completely restored after the subsequent annealing at a temperature of 700°C. A weak change in the dHc2/dT derivative upon irradiation is explained by the fact that the irradiated samples are described by the “pure” limit of the theory of disordered superconductors. The suppression of Tc upon disordering may be due to the isotropization of the originally anisotropic (or multicomponent) superconducting gap or to a decrease in the density of electronic states at the Fermi level Полный текст |
