Tungsten doped titanium dioxide films with both transparent conducting oxide (TCO) and photocatalytic properties were produced via aerosol-assisted chemical vapor deposition of titanium ethoxide and dopant concentrations of tungsten ethoxide at 500 °C from a toluene solution. The films were anatase TiO2, with good n-type electrical conductivities as determined via Hall effect measurements. The ...

The title compound, [Al(2)(C(32)H(48)NO(3))(2)], exists as a dimer with bridging ethoxide groups. It was isolated from a reaction mixture of the parent ligand and trimethyl-aluminium in tetra-hydro-furan. The geometry around the Al(III) atom is a slightly distorted trigonal-bipyramid, typical of atrane derivatives.

Close lattice matching with a MgAl2O4 (0 0 1) substrate has been used to synthesize thin films of a rare spinel-like polymorph of MgO (b-MgO) that is unstable in bulk form. The film is produced by spin casting an acetate-substituted Mg-ethoxide precursor, which forms a crystalline magnesium acetate phase at room temperature. Pyrolysis of most organic constituents occurs during continuous heatin...

We report single molecular sheets of niobate prepared by a simple bottom-up approach using hydrothermal synthesis of niobium ethoxide with the aid of triethanolamine as a structural modifier: the high kinetic stability of these molecular entities against self-assembly allows them to mix well with other colloids and facilitates their extensive electronic interactions and thus photocatalytic hydr...

Abstract Despite garnering so much research interest, the potential technological developments of perovskites are limited due to instability in polar solvents. Here, it is discovered that upon exposure ethanol, initial cubic cesium lead bromide nanocrystals (CsPbBr 3 NCs) undergo a phase transformation from orthorhombic phase. Further water leads formation CsPbBr perovskite nanoaggregates, whic...

Studies of the modes of adsorption and the associated changes in electronic structures of renewable organic compounds are needed in order to understand the fundamentals behind surface reactions of catalysts for future energies. Using planewave density functional theory (DFT) calculations, the adsorption of ethanol on perfect and O-defected TiO(2) rutile (110) surfaces was examined. On both surf...

The conversion of ethanol to ethylene, which is one of the most important feed stocks for the petrochemical industry, is of particular commercial interest. Two mechanisms, stepwise and concerted, of the ethanol dehydration to ethylene in the presence of water have been investigated by the ONIOM model (14T/120T) with B3LYP/6-31g(d,p):UFF method. In the stepwise mechanism, the coadsorbed water as...

A general, simple, practical and convenient method has been described for the synthesis of anesthetic drug thiopental using thiourea in the presence of sodium ethoxide. Anesthetic drug of thiopental was prepared in two stages; during the first stage, the alkylation of mthyl cyanoacetate was performed which was then to be followed by cyclization. Alkylation of methyl cyanoacetate which was perfo...

Ta2O5 films of 10-150 nm thickness were prepared by oxygen-assisted pyrolytic LPCVD at 450-490°C from tantalum penta ethoxide and 0 2 with N2 diluent. Silicon wafers 150 mm in diameter were used as substrates with a novel LPCVD reactor. The films were annealed in dry 0 2 a t 700-800°C. Compositional, structural, and electrical evaluations demonstrate that these uniform, pure, and conformal Ta2O...

In the present report, generation of Tantalum oxyfluoride and oxynitride upon ammonolysis gel obtained from modified tantalum-alkoxo complexes is reported. To best our knowledge, this first report formation tantalum thin films via β-diketone complex [Ta(OEt)4(CF3COCH2COCH3)]m. The integration nitrogen fluorine in lattice sites metal oxides leads to significant reduction bandgap, resulting their...
