Malerials-30 per cent hydrogen peroxide (Baker and Adamson, phosphorus-free) and the ammonium molybdate, (NHJ6lMo7024.4Hz0, wereused. The Fiske and SubbaRow (I) reagent was prepared by adding 0.5 gm. of purified (1) 1-amino-2naphthol-4-sulfonic acid (Eastman Organic Chemicals) with mechanical stirring to 200 ml. of freshly prepared 15 per cent sodium bisulfite (anhydrous), followed by 1.0 gm. o...

At present, composite photocatalysts containing MoS2 as a co-catalyst and a subjective semiconductor material are usually obtained via various complex reduction methods using NH4MoS4 or Na2MoO4 as a precursor. In this work, a simple method was proposed to synthesize MoS2-TiO2 composite photocatalysts via mechanochemistry using MoS2 as a direct precursor. 4.0% MoS2-TiO2 after ball-milling at 300...

The effect of adenylate cyclase activation on the in vitro contractures of control and malignant hyperpyrexia susceptible (MHS) porcine muscle was investigated. While fluoride and molybdate ions potentiated drug-induced contractures in control muscle, other activators of adenylate cyclase (forskolin and noradrenaline) did not. Furthermore, fluoride and molybdate had no effect on MHS skeletal mu...

In this work, the thermal stabilities of a series of polyethylene glycols (PEG 4000, 6000 and 10000) were investigated after compositing with different kinds of inorganic salts, such as ammonium molybdate tetrahydrate (AMT), NH4VO3, (NH4)2SO4, NH4NO3, Na2SO4, Na2MoO4. It was first observed that all the ammonium salts exerted leveling effects for the thermal stabilities of the PEGs. In other wor...

To compare the corrosion inhibition behaviors of rust inhibitors with different mechanisms on steel bars, resistance effect sodium molybdate (Na2MoO4), chromate (Na2CrO4), benzotriazole (BTA), N-N dimethyl ethanolamine, (Na2MoO4) + and (Na2CrO4) (BTA) bars in a simulated chloride concrete pore solution was studied. The effects types were assessed by electrochemical impedance spectroscopy (EIS),...

Achromatium oxaliferum is a large, morphologically conspicuous, sediment-dwelling bacterium. The organism has yet to be cultured in the laboratory, and very little is known about its physiology. The presence of intracellular inclusions of calcite and sulfur have given rise to speculation that the bacterium is involved in the carbon and sulfur cycles in the sediments where it is found. Depth pro...

The mouse L929 fibroblastic cell line presents low, but detectable, levels of the mRNA encoding xanthine oxidoreductase under basal conditions, and it responds to type I and type II interferons by inducing the expression of the transcript [Falciani, Ghezzi, Terao, Cazzaniga, and Garattini (1992) Biochem. J. 285, 1001-1008]. This cell line, however, does not show any detectable amount of xanthin...

A glucocorticoid receptor-associated Mr approximately 90,000 non-hormone-binding protein was purified and characterized. The molybdate-stabilized nonactivated rat liver glucocorticoid-receptor complex (Mr approximately 300,000) was immunoadsorbed on cyanogen bromide-activated Sepharose 4B to which a monoclonal IgG 2a antibody directed against the activated rat glucocorticoid receptor (Mr approx...
