TL;DR: In this article, an extensive mechanical milling was used to make MgH2-Tm (Tm=3d-transition elements Ti, V, Mn, Fe, Ni) nanocomposite powders.

TL;DR: In this article, the authors present a systematic study of structural modifications and hydrogen absorption-desorption kinetics of ball-milled magnesium hydride, and they show that after only 2 h of milling, a metastable orthorhombic (γ)-morphological phase is formed.

TL;DR: In this article, the use of milling tools for tuning the microstructure of metals to modify their hydrogenation properties is discussed, and more specialised techniques such as solid/liquid based methods are mentioned along with the common characteristics of mechanochemistry as a way of synthesizing hydrogen storage materials.

TL;DR: In this paper, the authors review the fundamentals of the Mg-H system and look at the recent advances in the optimisation of magnesium hydride as a hydrogen storage material through the use of catalytic additives, incorporation of defects and an understanding of the rate-limiting processes during absorption and desorption.

TL;DR: In this paper, the hydrogen storage properties of a new composite MgH2+V prepared by ball milling were presented. But the results were limited to hydrogen desorption at 473 K under vacuum and re-absorbation at room temperature.
