Published 1989Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: An Auger electron spectroscopy study has been made of the depth profiles of films of Y-Ba-Cu-O compounds. The films were produced by electron beam and ion plasma sputtering onto various substrate types. The specimens were annealed in air at temperatures ranging between 450 and 900 °C. The effective diffusion coefficients for the film and substrate constituents have been estimated. The depth profiles of films annealed at 600 °C reveal composition oscillations in the region adjacent to the surface. These composition oscillations are assumed to arise from the phase transformations that occur at 600 °C in films of the Y-Ba-Cu-O system.Type of Medium: Electronic ResourceURL: -

ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: X-ray studies of the crystal structure in Pb1−x(Li1/2La1/2)xZr1−yTiyO3 solid solutions at the phase transition from a paraelectric state into ordered states near the triple ferroelectric–antiferroelectric–paraelectric point of the "Ti-content–temperature" phase diagram are carried out. Analysis of the shape of characteristic x-ray lines indicates the presence of two-phase nuclei with ferroelectric and antiferroelectric types of dipole ordering in the crystal lattice of the solid solutions above the point of the paraelectric phase transition (the Curie temperature). © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1090-6509Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The asymptotic behavior of the spectra for large values of the scattering vector for the case of elastic multiple small-angle neutron scattering (SANS) is investigated theoretically and experimentally. An expansion of the spectrum in terms of the reciprocal of the magnitude of the momentum transfer is obtained taking account of the influence of the instrumental line. It is shown that, to within some factor, the leading term of the expansion is identical to the differential single-scattering cross section averaged over a statistical ensemble of particles; several subsequent terms in the expansion are calculated and the range of applicability of the resulting expressions is determined. The asymptotic behavior of the multiple SANS spectrum is measured, using a two-crystal neutron spectrometer, for samples of an HTSC ceramic, the alloy Fe-Ni, and Al powder. The agreement between the experimental results and the theoretical predictions is analyzed.Type of Medium: Electronic ResourceURL: -

The method of potentiometric titration in an aqueous—organic medium (70% ethanol, ionic strength 0.01M LiNO3, 298 K) has been used to study the acid-base and complexing properties of the title compound. The ligand thus prepared forms 1∶1 complexes with Cu2+, Co2+, Zn2+, and Ni2+ cations; formation of hydroxocomplexes MOHL+ has been observed in the case of Zn2+ and Cd2+.Type of Medium: Electronic ResourceURL: -

It has been shown that in the CuL1 complex the metal ion is pentacoordinated by three nitrogen atoms and two phosphinyl groups of the ligand and has a tetragonal-pyramidal environment. The conformation of the coordination polyhedron for the CuL1 complex depends on the solvent. In the CoL1 complex, as well as in the CoL2 complex, where L2 is 1,4,7-tris(2-diphenylphosphinylethyl)-1,4,7-triazacyclononane, the Co2+ ion has an octahedral environment and is bound to all donor atoms of the ligands.Type of Medium: Electronic ResourceURL: -

The protonation constants of the compounds synthesized and some of their analogs were determined by potentiometric titration in 70 % aqueous ethanol and in nitromethane. The nitrogen atoms of the ring are the protonation sites in all of the systems studied. The regularities of the variation of protonation constants have been explained by the formation of intramolecular hydrogen bonds. The conformational possibilities of the formation of H-bonds in the cations of the ligands have been examined by molecular mechanics.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1573-9171Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract We have determined the composition and stability of d- and dℝ-tartrates of Dy3+. In the pH region 4.0–7.0, we have shown that binuclear particles are formed. The relative stability of isomeric d- and dℝ-tartrates of Dy3+ is determined only by the statistical factor. From data on the paramagnetic birefringence effect, binuclear d- and dℝ-tartrates of dysprosium(III) have a polycyclic structure including six five-membered metallocycles, two of which are condensed with the central twelve-membered ring. The paramagnetic anisotropy of Dy3+ in the studied dimers has twice the absolute value of the anisotropy of the aqua ion of Dy3+ (Δk=−2860·10−29 cm3). Using the magnetic susceptibility measurements, we have demonstrated the virtually complete absence of Dy3+−Dy3+ magnetic interactions in binuclear d- and dℝ-tartrates.Type of Medium: Electronic ResourceURL: -

A molecular mechanics technique (Dashevskii-Plyamovatyi model) was used to model the structure of the ligand and hydrate surroundings of dysprosium(III) in DyH2L+. Theoretical molar constants of magnetic double refraction calculated from the molecular mechanics data (CONKERR program) were compared with the experimental values; the most probable models of the surroundings of the dysprosium(III) are established.Type of Medium: Electronic ResourceURL: -
