The material's states of vanadium are present, but an overall reduction has occurred in hydrogenation. Simulation shows that a vanadium (IV) species is now present, as demonstrated by the emission at 516.1 eV, which is close to the emission of V(IV) ...…
The vanadium hydride materials V(IV)-100 and V(IV)-25C-H2 were tested for room temperature hydrogen storage to compare their activity to V(III) alkyl hydride gels previously synthesized by our group. 9c Hydrogen PCT adsorption-desorption isotherms we...…
Vanadium, V–5Cr, and V–5Ti alloys were prepared from 99.9% pure vanadium by arc melting in an argon atmosphere. The nuggets were cold-rolled and punched into tensile specimens for in situ straining experiment with a gauge size of 2×7 mm2 and 0.1 mm i...…
A vanadium aryl hydride gel was prepared by thermal decomposition and subsequent hydrogenation of tetraphenyl vanadium and evaluated for electrochemical and hydrogen storage performance. Characterization by IR, XRD, XPS, nitrogen adsorption, and TGA ...…

By examining tiny particles of gold with powerful X-ray beams, scientists hope they can learn how to cut down on harmful carbon monoxide emissions from motor vehicles.Carbon monoxide is a colorless, odorless and dangerous gas produced by…
The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Touri…
OPEC+, an oil producers' alliance led by Saudi Arabia and Russia, stuck to its original plan to increase output by just 432,000 b/d in June, continuing to defy calls from major consumers led by the United States to pump more oil to keep prices down.…
