A nanohybrid of CdS and HCa2Nb3O10 with enhanced separation of charge carriers was conveniently prepared by self-assembly of negatively charged HCa2Nb3O10 nanosheets with the existence of Cd2+ followed by sulfuration. With CdS working as a visible light absorbent, HCa2Nb3O10, with a wide bandgap...

The heats of formation of the Y-Sb system have been,measured using a differential direct isoperibol calorimeter.The following values (kcal (g atom)−1) were obtained for the various compounds (reaction in the solid state at 300 K): Y3Sb, ΔHfrom = −15.3 ± 0.5; Y5Sb3, ΔHfrom. = −23.0 ± 0.5; YSb...

A phase diagram is proposed for the yttrium-antimony system based on thermal, microscopic, chemical and X-ray analyses. An inverted peritectic reaction develops as a result of antimony additions, lowering the 1475° C transformation temperature of yttrium to 1462° C. Eutectic reactions occur at...

In the present paper, we have investigated the high-pressure structural phase transition of yttrium pnictides (YX; X = N, P, As and Sb). An extended interaction potential (EIP) model has been developed (including the zero point energy effect in three body interaction potential model). Phase tran...

Pressure induced structural aspects of NaCl-type (B1) to CsCl-type (B2) structure in yttrium and scandium antimonides are presented. An effective interionic interaction potential (EIOP) with long-range Coulomb, van der Waals (vdW) interaction and the short-range repulsive interaction upto second...

A method for producing single-phase cadmium stannate thin films is reported. Polycrystalline films were prepared by RF sputtering onto water-cooled Corning glass substrates, followed by a high temperature anneal. Resistivities as low as 1.28 × 10−4 ohm·cm have been achieved, lower than any pre...

The sensitivity of cadmium stannate (CTO) performance to both sputtering and annealing conditions was investigated. Films treated by the standard proximity anneal in contact with a CdS film displayed an electrical resistivity of ~2.2×10−4 Ω cm, high mobility (~57 cm2/V s), and >90% transmissio...

Cadmium stannate (Cd2SnO4) thin films were coated on Corning 1737 glass substrates at 540 °C by spray pyrolysis technique, from the aqueous solution of cadmium acetate and tin (II) chloride precursors. Fluorine doped Cd2SnO4 (F: Cd2SnO4) thin films were prepared by adding ammonium fluoride in t...

A reliable transparent front contact of cadmium stannate (CTO) and titanium oxide (TiO2) entirely deposited by magnetron sputtering has been studied and applied to build standard dye-sensitized solar cell. CTO gives very high average optical transmittance (Tavg ≥ 90%) along with competitive she...

Cadmium stannate thin films were prepared by spray pyrolysis technique using cadmium acetate and tin(II) chloride precursors at substrate temperatures 450 °C and 500 °C. XRD pattern confirms the formation of orthorhombic (1 1 1) cadmium stannate phase for the film prepared at substrate tempera...

The cadmium stannate samples were prepared by chemical co-precipitation method using stannic chloride pentahydrate (SnCl4·5H2O) and cadmium chloride (CdCl2) as precursors by carefully controlling the preparative parameters. The effect of calcining temperature on the phase, microstructure, morph...

Single phase cadmium stannate thin films were deposited on glass substrates through rf magnetron sputtering by varying rf power and keeping substrates at room temperature. The effect of rf power on physical properties of the films and the correlations were systematically investigated. It has bee...

The anthropogenic phosphorus scarcity and phosphorus-induced pollution call for a substantial improvement of phosphorus use efficiency (PUE). Using substance flow analysis, phosphorus flow charts for an agriculture city with fast growing aquaculture, i.e. Zhangzhou in China for the period 1995–...

An increasing number of studies have suggested that global phosphate rock (PR) extraction will reach a peak in the coming decades, with subsequent implications for food security. This paper focuses on peak phosphorus in China, which serves as an "early warning indicator" for phosphorus security....

The synthesis and reactions of bis(cyclooctatetraene)iron(0) are described. An interpretation is offered of the mechanism of the oligo- and cooligomerization of different unsaturated hydrocarbons promoted by iron complexes.

Hollow carbon nanobags have been obtained by the chlorination of bis(cyclopentadienyl)tungsten dichloride (W(C5H5)2Cl2) at 400 and 900 °C. Transmission electron microscopy images indicate an incipient graphitisation at higher reaction temperatures and an increase in the average dimensions of th...

Reaction of bis(cyclopentadienyl)molybdenum dichloride 1 in ethanol with 1,3-propanedithiol 2 either in the presence of base or as its thallium derivative produces [Mo(η-C5H5)2(SCH2CH2 CH2S)] (5) containing a 6-membered ring with a chair conformation, structurally characterized by X-ray diffrac...

The aim of this study was to examine the effect of chromium(III) and iron(III) and molybdenum(III) and nickel(II) and their combinations on cyto-, genotoxicity and mutagenicity in BALB/3T3 and HepG2 cells.The results obtained from cytotoxicity assays indicate that there are differences between B...
