We have measured the thermopower (S) of hole-doped LaMnO3 systems in order to see its dependence on the Mn4+ content as well as to investigate other crucial factors that determine S. We have carried out hole doping (creation ...

La2-xNiO4, La2-xSrxNiO4 and related layered nickelates have been investigated for possible presence of superconductivity. While there is clear onset of diamagnetism around 20 K in many of these nickelates, we do not, ...

Inorganic–organic hybrid compounds of the amino acid alanine have been prepared and characterized for the first time. Thus by the reaction of β-alanine with copper salts, one-dimensional hybrid chain compounds of the ...

HeI photoelectron spectra of 1:1 electron donor-acceptor complexes are discussed in the light of molecular orbital calculations. The complexes discussed include those formed by BH3, BF3 and SO2. Some systematics have been ...

The polyoxometallate Keggin (αtype) [PMo4.27W7.73O6−40] [H3N(CH2)6NH2+3]3, involving molybdenum and tungsten present in both V and VI oxidation states, has been synthesized under hydrothermal conditions and its structure ...

LaMnO3+δ samples with Mn4+ content up to 50% have been prepared by different methods. The structure of LaMnO3+δ changes from orthorhombic to cubic (via rhombohedral) with increase in the Mn4+ content. LaMnO3+δ samples ...

Glasses, prepared from the melts of Bi2(Ca, Sr)n+1 CunO2n+4 (n=1,2 and 3) have been characterized by various techniques. These glasses exhibit relatively high dielectric constants, high electrical conductivity, a ...

Thiol-derivatised nanoparticles of Au, Pt and Ag (diameter 1-10 nm) forming superstructures, are prepared by the acid-facilitated transfer of well characterized particles in a hydrosol to a toluene layer containing the thiol.

Vapor-phase clusters from ethanol-water liquid mixtures of varying compositions, generated by sampling the binary vapor in equilibrium with the liquid mixture, were examined with the aid of a time-of-flight mass spectrometer. ...

A comparative study of the magnetic properties of a few members of the Ln(0.5)Sr(0.5)CoO(3) family with different radii of the A-site cations, 〈rA〉, in the range 1.19-1.40 A has been carried out. The apparent Tc (where the ...
