## Abstract The effect on the hydrogen storage attributes of magnesium hydride (MgH~2~) of the substitution of Mg by varying fractions of Al and Si is investigated by an ab initio planeβwave pseuodopotential method based on density functional theory. Three supercells, namely, 2Γ2Γ2, 3Γ1Γ1 and 5Γ1Γ1
This work investigates the thermodynamics and kinetics of magnesium hydride decomposition by analyzing isotope effects in hydride and deuteride samples. Complete pressure composition desorption isotherm measurements of MgD 2 are reported for the first time. Deuterium desorption enthalpy and entropy
