We describe preparation of the ternary intermetallic Li 2 MgPt and determination of its crystal structure and hydrogen sorption behavior. Phase formation was suggested by density functional theory calculations. The compound crystallizes in the cubic

Our theoretical modeling of Li2MgX systems and their hydrides with density functional theory (DFT) suggested the existence of Li2MgIr. Verifying the DFT results, we have synthesized Li2MgIr and determined its crystal structure and hydrogen sorption b

An investigation of Li2MgSi, with particular emphasis on its potential as a hydrogen storage material, is reported. A cubic P 4 ¯ 3 m crystal structure, differing from previous determinations, is established. We find that the material reversibly sor

Quaternary Li−B−N−H hydrides with the α-phase crystal structure form over a range of compositions between Li3BN2H8 and Li4BN3H10 and have up to 11.9 wt % hydrogen capacity. Previous work has focused on the nonequilibrium Li3BN2H8 composition c

We report large reversible hydrogen storage in a new coupled system, LiBH 4 /CaH 2 , via the reaction 6LiBH 4 + CaH 2 ↔ 6LiH + CaB 6 + 10H 2 having a theoretical hydrogen capacity of 11.7 wt% and an estimated reaction enthalpy of Δ H = 59 kJ/mol H

The coupled system LiBH4 + 1/2MgH2 ↔ LiH + 1/2MgB2 + 2H2 demonstrates improved hydrogen cycling thermodynamics compared to either LiBH4 or MgH2 alone; in effect, formation of MgB2 “destabilizes” the decomposition of LiBH4. Here we establish the

We have examined the effect of adding small quantities of Fe, Ni, and Zn, or their dichlorides, on the dehydrogenation temperature of the new quaternary hydride material LiB 0.33 N 0.67 H 2.67 . NiCl 2 proved to be an especially effective dehydrogena

We recently reported the synthesis of a new quaternary hydride in the lithium−boron−nitrogen−hydrogen quaternary phase diagram with the approximate composition LiB0.33N0.67H2.67 having a theoretical hydrogen content of 11.9 wt %. This new compo

Rare earth compounds RFe 12− x M x with tetragonal ThMn 12 -type structure are of great research interest for potential applications as permanent magnets. These materials are known to serve as the precursors for nitriding and hydriding processes wh

Equivolume composites of melt-spun Tb0.5Dy0.5Fe2 in an Fe matrix have been consolidated by hot pressing over a range of temperatures. We find that both the magnetic field dependence of the magnetostriction λ(H) and the torque response Rτ of these m
