Hydrogen storage systems based on the combination reactor concept are promising for application of future complex hydride materials with high storage capacities and low reaction kinetics at moderate operating temperatures. In such a reactor, a fast reacting metal hydride is added to a complex hydride material in a separate compartment of the tank combining the advantages of the high storage cap...

2014 The heterogeneous equilibrium in the InGaAsP/HCl/H2 system has been studied at pressure and temperature conditions pertaining to the hydride-VPE growth. The results have been compared with the available experimental data on the growth of the above quaternary alloys lattice-matched to InP. A remarkably good agreement has been achieved with some existing data. Possible causes of discrepancie...

Complex metal hydrides have recently gained interest as solid electrolytes for all-solid-state batteries due to their light weight, easy deformability, and fast ion mobility at elevated temperatures. However, increasing low conductivity room temperature is a prerequisite application. In this review, two strategies enhance in complex hydrides, nanostructuring nanocomposite formation, are highlig...

beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...

The desorption behaviors of hydrogen from high entropy alloy TiZrVMoNb hydride surface have been investigated using the density functional theory. (110) has determined to be most preferable for hydride. Due lattice distortion and heterogeneous chemical environment in HEA hydride, is found complex. A comparison molecular atomic reveals that prefers desorb states rather than during process. To co...

Abstract Molecular β‐diketiminato (BDI) calcium hydride and n ‐hexyl derivatives are shown to display contrasting reactivities toward bis(pinacolato)diboron (B 2 pin ). Whereas the dimeric constitution of is retained during formation an unusual diborane(6) dianion, initially organocalcium reagent converted a diboranate monomer, [(BDI)Ca{pinB‐Bpin( ‐hex)}]. Attempts effect heterolysis B−B bond t...

Current state-of-the-art epitaxial growth techniques employ various metalorganic and hydride gases to deliver constituent species to the substrate surface, particularly high vapor pressure species such as phosphorus and sulfur. Gas source molecular beam epitaxy (GSMBE) utilizes hydride gas sources and solid elemental sources. The more conventional growth approach, molecular beam epitaxy (MBE), ...
