Medium energy ion scattering (MEIS), using 100 keV H incident ions, has been used to investigate the growth of epitaxial films, up to thicknesses of ~200 Å, of V2O3 on both Pd(111) and Au(111). Scattered-ion energy spectra provide a measure of the average film thickness and the variations in this thickness, and show that, with suitable annealing, the crystalline quality is good. Plots of the sc...

The title mixed-ligand oxidovanadium(IV) compound, [VO(C(5)H(7)O(2))(2)(C(8)H(9)N(3))], contains a V(IV) atom in a distorted octahedral coordination, which is typical for such complexes. The vanadyl group and the N-heterocyclic ligand are cis to each other. The coordination bond is located at the endocyclic N atom of the benzimidazole ligand. Intra-molecular hydrogen bonds between the exo-NH(2)...

Exploring the chemistry of vanadyl ions (VO2+) with bis-β-diketone ligands, in pyridine reactions of vanadyl sulfate with 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)benzene (H4L1) and 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-pyridine (H4L2), two novel clusters, [(VIVO)4(H2L1)4(py)4] (1) and [(VVO)4(VIVO)2 (O)4(L2)2(py)6] (2) were prepared and characterized. Due to the conformational flex...

In metal air battery, oxygen reacts with lithium ions on the cathode side of cell which makes it much lighter than conventional cathodes used in Li-ion batteries. Density functional theory (DFT) study is employed order to investigate surfaces of, (Rutile) R-MnO 2 , TiO and VO (MO ), act as catalysts metal-air Adsorption co-adsorption K (110) β-MO surface investigated, important discharging char...

The dinuclear mol-ecule of the title complex, [VOCl{μ-OC(Me)2P(iPr)2-κ(2) O}]2 or [V2(C9H20O2P)2Cl2O2], which was obtained due to an unexpected oxidation reaction, is centrosymmetric, with the inversion centre located in the middle of the central V2O2 core. These core O atoms arise from the symmetry-related 2-(diiso-propyl-phosphor-yl)propan-2-olate dianions. The V(IV) atom is additionally bond...

Because vanadium ions such as vanadyl (VO) and vanadate (VO3−) ions were demonstrated to normalize blood glucose levels of diabetic animals and patients, the action mechanism of vanadium treatment has been of interest. In this study, we focused on understanding interactions among trace elements in diabetic rats, in which a multitracer technique was used. The effects of vanadyl sulfate (VS)-trea...

Abstract The potential battery electrode material V 2 O 3 /C has been prepared using a sol–gel thermolysis technique, employing vanadyl hydroxide as precursor and different organic acids both chelating agents carbon sources. Composition morphology of resultant materials were characterized by X-ray diffraction, Raman spectroscopy, scanning transmission electron microscopies, physical sorption, e...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

Hepatic cholesterol synthesis in rabbits, as measured by the incorporation of C(14)-labelled acetate, was inhibited by addition of non-toxic amounts of vanadyl sulfate (0.05 per cent VOSO(4).2H(2)O) to the diet. This diet reduced excess aortic cholesterol in cholesterol prefed rabbits when fed during the 6 weeks immediately following a 4 week period of cholesterol feeding.
