Summary: Understanding the interaction between hydrogen and metals is crucial for surface science, particularly in studying the corrosion of metals in aqueous environments. This study used first-principles Density Functional Theory (DFT) calculations to investigate the mechanisms of hydrogen adsorption and crystalline magnesium hydride formation under aqueous conditions. The Electron Localisation Function (ELF) was identified as a useful indicator for predicting stable hydrogen adsorption on magnesium surfaces. The research suggests that the adsorption of atomic hydrogen, hydroxyl radicals, and atomic oxygen on the surface can enhance electron localisation in specific sub-surface regions, leading to the formation of thermodynamically stable sub-surface hydride layers.

Summary: This study demonstrates the transformation of zirconia additive into zirconium hydride and its significant impact on lowering the dehydrogenation temperature of magnesium hydride. The results provide evidence of the chemical transformation of zirconia and support the formation of an active in situ product, zirconium hydride, which enables low temperature dehydrogenation of magnesium hydride. The study also highlights the dispersion of tiny nanoparticles on the surface and the formation of highly active in situ nanocatalysts.

Summary: The incorporation of (Ni-V2O3)@C nanoparticles was introduced to enhance the hydrogen storage performance of Mg/MgH2 systems. The composite sample exhibited improved hydrogenation and dehydrogenation kinetics, with a lower initial hydrogenation temperature and higher hydrogen absorption and desorption capacities compared to pristine MgH2. The addition of (Ni-V2O3)@C nanoparticles acted as a hydrogen pump, promoting hydrogen diffusion and dissociation within the Mg/MgH2 system.

Summary: The configuration of phase change materials in hydrogen storage tanks affects the storage performance. Sandwiched MH-PCM units have faster heat transfer and reaction rates due to larger transfer area and smaller thermal resistance. The amount of PCM affects the reaction fraction and can slightly impact absorption and desorption rates when reduced within sufficient limits.

Summary: The investigation provides new insights into the structure and chemical composition of pyrite thin films, highlighting the chemical inhomogeneities and proposing the hypothesis that the iron sulfuration process induces diffusion, resulting in the formation of a porous layer. The findings suggest that mechanisms operative in the synthesis of surface hollow structures at the nanoscale are also active in the formation of pyrite thin films.

Summary: ZnO thin films were grown by e-beam evaporation at low temperatures on Al2O3 and Si substrates, with no significant differences observed between the two substrates. The growth mode of ZnO at low temperatures was found to be a gradual bilayer system, with the emergence of Zn-rich whiskers at extremely low temperatures. These results provide a promising route to enhance the properties of ZnO films below the typical high temperature window.

Summary: This study presents a reaction and kinetic model of the sulfuration reaction of metallic iron thin films into monosulfides. The evolution of the transport properties of the films during their sulfuration reaction was observed by slowing down the reaction. The study reveals that the sulfuration reaction involves two stages, including the transformation of iron into hexagonal pyrrhotite and a partial crystallization of pyrrhotite into ortho-rhombic pyrrhotite.

Summary: This study explored the application of mechanical energy as a non-thermal method to drive hydrogen emission from undoped sodium alanate at room temperature. The results showed that mild rubbing of NaAlH4 pellets under vacuum led to intensive and instantaneous gas emission, with hydrogen being the dominant species. The emission process involved multiple first-order reactions with widely ranged time constants. It was suggested that the tribochemical reactions can be triggered by plastic deformation and shearing. A linked diffusion-wear model of NaAlH4 triboinduced dehydrogenation was proposed to explain the empirical findings.
