Regeneration of lithium aluminum hydride.
Lithium aluminum hydride (LiAlH(4)) is a promising compound for hydrogen storage, with a high gravimetric and volumetric hydrogen density and a low decomposition temperature. Similar to other metastable hydrides, LiAlH(4) does not form by direct hydrogenation at reasonable hydrogen pressures; therefore, there is considerable interest in developing new routes to regenerate the material from the ...
متن کاملStark deceleration of lithium hydride molecules
We describe the production of cold, slow-moving LiH molecules. The molecules are produced in the ground state using laser ablation and supersonic expansion, and 68% of the population is transferred to the rotationally excited state using narrowband radiation at the rotational frequency of 444 GHz. The molecules are then decelerated from 420 m/s to 53 m/s using a 100 stage Stark decelerator. We ...
متن کاملReduction of Halomethanes with Lithium Aluminum Hydride
A study has been made of t he reactions of lithium aluminum hydride with methyl bromide, methylene chloride, meth ylene bromide, methylene iodide, chloroform, bromoform, and carbon t etrachloride. Except for hydrogen and unreacted h alida, essentia lly pure methane was formed in each case. The amount of hydrogen evolved increased with the n umber of halogen atoms in the molecule, reaching a max...
متن کاملAb initio treatment of electron correlations in polymers: lithium hydride chain and beryllium hydride polymer
Correlated ab initio electronic structure calculations are reported for the polymers lithium hydride chain [LiH]∞ and beryllium hydride [Be2H4]∞. First, employing a Wannier-function-based approach, the systems are studied at the Hartree-Fock level, by considering chains, simulating the infinite polymers. Subsequently, for the model system [LiH]∞, the correlation effects are computed by consider...
