Determination and interpretation of the hydriding and dehydriding kinetics in mechanically alloyed LaNiMg17 composite

Rare earth–transition metal–magnesium compounds—An overview

“…The extensive studies on Mg 2 NiH 4 and related hydrides have been extended towards rare earth based intermetallic compounds in recent years [122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140]. The rare earth-transition metal-magnesium compounds are currently widely investigated with respect to their hydrogen storage capacity.…”

“…Cobalt seems to enhance the hydrogenation properties [132]. The article size has a drastic influence on the discharge capacity [124,134] and mechanical alloying improves the kinetic properties. This can be explained by the defects introduced during the mechanical alloying process as well as the increased specific surface area.…”

Effect of hydrogen pressure on hydriding kinetics in the Mg2−xAgxNi–H (x=0.05, 0.1) system

“…In the previous series of papers [17], we have successfully studied the effect of temperature on the absorption/desorption of hydrogen for various kinds of hydrogen storage materials by using our model. Here we focus on the influence of pressure on absorption/desorption kinetics.…”

Ce20Mg19Zn81: a new structure type with a giant cubic cell

“…The influence of different factors (e.g. mechanical alloying, or rare earth or transition metal substitution) on the discharge characteristics of these alloys has also been investigated Zhang et al, 2005;Li et al, 2005). We present here the results of a crystallographic study of a new transition metal-rich compound, viz.…”
