In this paper, a mathematical model for the cycling electrochemical capacity of hydride electrodes was deduced on the basis of activation and degradation of hydride materials. A cycle life model was deduced on introducing the activation and degradation factors into the electrochemical polarization equation which included concentration polarization, phase transformation polarization and electroc...

The controlled out-diffusion method was employed to induce a nuclear reaction in a palladium (Pd) plate with a MnOx film. The time-resolved mass spectra for Pd deuteride revealed tritium (T) production during the outdiffusion experiment. Similar time behaviors of mass number 1-4 and 6 in the spectra was also observed for Pd hydride. Film blackening was observed for most Pd deuteride as well as ...

Hydride generation techniques are used routinely for the determination of As, Se, and Sb in environmental samples. Advantages include high sensitivity, simplicity and relative freedom from interferences. The current method for the hydride generation determination of As and Se, as outlined in the USEPA manual SW-846, utilizes zinc slurry methodology. A batch type method is described. Batch type ...

We studied proton beam production from a laser ion source using hydrogen rich target materials. In general, gas based species are not suitable for laser ion sources since formation of a dense laser target is difficult. In order to achieve reliable operation, we tested hydride targets using a sub nanosecond Q-switched Nd-YAG laser, which may help suppress target material consumption. We detected...

The title compound, C(16)H(12)O(2), was synthesized from naphthalene-2,7-diol and prop-2-ynyl 4-methyl-benzene-sulfonate in the presence of sodium hydride. The crystal packing exhibits inter-molecular non-classical C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

The molecular calcium hydride, [(BDI)CaH]2 (BDI = HC{(Me)CN-2,6-i-Pr2C6H3}2), effects the slow hydrodehalogenation of C6H5X (X I, Br) to provide benzene and respective dimeric halides, [(BDI)CaX]2. Although a similar reaction with fluorobenzene was non-discriminating, analogous hydrogenation chlorobenzene observed, albeit this process yields hydride-chloride as alkaline earth-containing product...
