A hypothetical hydrogenation catalyst consisting of porous, catalytically active particles embedded with metal hydride powder was evaluated. The metal hydride provides temporarily additional hydrogen if the mass transfer rate of the hydrogen to the internal of the particle is not sufficient. A numerical ...

136 In the case of the Ni(0) complex, C‒H bond activation occurs via a LLHT mechanism without generating a Ni(II) hydride phenyl intermediate because of the compact size of the nickel metal which decreases the distance between the benzene and alkene in the transition state and the ...
We have successfully fabricated transparent conductive mesoporous indium tin oxide (TCM-ITO) films by a screen-printing method. The TCM-ITO films possess approximately 22 nm mesopores and obtain electrical conductivity up to 14.96 S/cm by adjusting
High-throughput computational methods capable of predicting, evaluating and identifying promising synthetic candidates with desired properties are highly appealing to today’s scientists. Despite some successes, in silico design of crystalline materials
A thermally coupled metal hydride hydrogen storage and fuel cell system This paper examines the ability of metal hydride storage systems to supply hydrogen to a fuel cell with a time varying demand, when the metal hydride tanks... BD Macdonald,AM Rowe - 《Journal of Power Sources》 被引量:...
Erythritol can be synthesized from periodate-oxidized starch or dialdehyde starch by a high-temperature chemical reaction in the presence of a metal catalyst [5, 6]. The chemical process has not been industrialized because it involves several intricate steps to get the erythritol and the starting ...
The results reported here are consistent with a new model in which the ChvE–sugar interaction with the periplasmic domain of VirA mediates conformational shifts of a hypothetical xenognostic phenol-binding protein (Xpb) that is bound to the linker domain of VirA, thereby increasing the apparent ...
A hypothetical example would be a one (1) inch sample of a material which is elongatable to at least 1.60 inches (4.06 cm) and which upon being elongated to 1.60 inches (4.06 cm) and released, will immediately, i.e. within less than one second, recover to a length of not more than...
Ziegler-Natta catalysts, in general, consist of two main components. One component is an alkyl or hydride of a Group I to III metal, most commonly Al(Et)3or Al(iBu)3or Al(Et)2Cl but also encompassing Grignard reagents, n-butyllithium, or dialkylzinc compounds. The second component is ...
