This study explores how the chemical interaction between magnesium hydride (MgH2) and the additive CrO3 influences the hydrogen/lithium storage characteristics of MgH2. We have observed that a 5 wt.% CrO3 additive reduces the dehydrogenation activati

This study explores how zirconia additive interacts with MgH2 to improve its hydrogen storage performance. Initially it is confirmed that the zirconia added MgH2 powder releases hydrogen at a temperature of about 50 °C below that of the additive fre

The current study highlights important information regarding how graphene oxide (GO) additive interacts with magnesium hydride (MgH2) and transforms to reduced graphene oxide (rGO). A mild reduction occurs during mechanical milling itself, whereas a

This study demonstrates how zirconia additive transforms to zirconium hydride and substantially lowers the dehydrogenation temperature of magnesium hydride. We pre- pared MgH2þxZrO2 (x 1⁄4 0.125 and 0.5) powder samples reacted for 15 min, 1 h, 5 h

Ecobenign and high-temperature-stable oxides are considered a promising alternative to traditional Bi2Te3-, Bi2Se3-, and PbTe-based thermoelectric materials. The quest for high-performing thermoelectric oxides is still open and, among other challenge

The current work explores the in-situ formation of TiH2 additive in a Ti/MgH2 nanocomposite system. Mild mechanical milling leaves Ti chemically unchanged, while formation of stable TiH2-x occurs upon strong mechanical milling. TiH2-x further transfo
