Summary: A high-energy ball milling method was used to synthesize nanocrystalline MgH2 powder samples catalyzed by Fe2Ti with different milling times (1 h, 3 h, and 10 h). The morphology and microstructure of the powders were characterized by scanning electron microscopy and X-ray diffraction. The diffraction profiles were analyzed using a convolutional multiple whole profile fitting algorithm to determine microstructural parameters of the composites. The dehydrogenation characteristics of the alloys were investigated using differential scanning calorimetry. An optimal milling time of 3 h was found to result in desorption at the lowest temperature. X-ray diffraction of partially dehydrided states confirmed a two-step H-release. The effect of milling time on the hydrogenation performance was evaluated using a Sievert-type apparatus, and the composite milled for 3 h exhibited the best overall performance.

Summary: Magnesium-based wastes were reprocessed by mechanical milling and used to produce hydrogen through hydrolysis. The material evolved during reprocessing and hydrogen was generated in a MgCl2 solution at 24 degrees C. The particle size, crystallite size, microstrain, and phase abundance changed during mechanical processing. Hydrogen yields of 70-90% were obtained after 30 min of reaction, depending on milling time. The reaction kinetics improved with milling time, and the hydrolysis curves could be fitted with a model limited by a three-dimensional geometric contraction process. Mg17Al12 and Fe played a role in promoting hydrogen production during the reaction.

Summary: This paper discusses the reprocessing of Mg scraps from sacrificial anodes manufacturing by mechanical milling for the production of H2 by hydrolysis. The effects of iron and graphite as additives to improve the hydrolysis reaction are presented. It has been found that pre-milling the scraps with 1.5 wt% of Fe for 10 hours followed by an extra milling with 5 wt% of graphite for 1 hour produces the best results. The addition of Fe accelerates the reaction rate by inducing microgalvanic coupling with Mg, while graphite acts as a process control agent during milling and contributes to size reduction of the material, resulting in faster H2 production.

Summary: A systematic study was conducted on the cryogenic H2 adsorption properties below the critical point of H2 on various adsorbents, comparing the density of adsorbed H2 and its temperature dependence with liquid H2. While most studies focus on new porous materials for H2 storage, this study investigated the density of adsorbed H2 below the critical point for metal-organic frameworks, super-activated carbon, and graphene nanoplatelets. It was found that the adsorption of superdense H2 in a monolayer state had a much higher density than liquid H2.

Summary: The effects of Ni7+ ion irradiation on Bi2Te3 thin films synthesized by e-beam evaporation were investigated. The films exhibited a polycrystalline rhombohedral structure. Irradiation caused a decrease in crystallite size and an increase in lattice strain. Raman spectra showed changes in A(1u)(1) modes with ion fluence. Surface roughness decreased due to the formation of nanocrystallites. XPS analysis confirmed the near stoichiometric composition of the films. The resistivity increased with ion fluence, resulting in a crossover behavior from n to p-type carriers. Compensation of bulk charge carriers was observed in the ion-irradiated films by adjusting the Fermi level.

Summary: Magnesium and its alloys are extensively studied for solid-state hydrogen storage, but there are challenges in the kinetics and thermodynamics of hydrogenation and dehydrogenation. Severe plastic deformation methods have been utilized to improve the activation, air resistance, and kinetics of Mg-based hydrogen storage materials by introducing ultrafine/nanoscale grains and crystal lattice defects. These deformed materials, particularly with alloying additives or second-phase nanoparticles, exhibit fast hydrogen absorption/desorption kinetics and good cycling stability. The study also highlights the application of severe plastic deformation methods in hydrogen binding-energy engineering and the synthesis of new magnesium alloys for reversible low/room-temperature hydrogen storage.

Summary: Building liquid channels in magnesium hydride by introducing lithium borohydride ion conductors improves its low-temperature hydrogen sorption. For example, 5 wt% LiBH4-doped MgH2 can release about 7.1 wt.% H-2 within 40 min at 300 degrees C, while pure MgH2 only desorbs less than 0.7 wt.% H-2. Additionally, the LiBH4-doped MgH2 exhibits faster desorption kinetics with more than 10 times enhancement compared to pure MgH2, and maintains a stable cyclic performance even after six absorption and desorption cycles. This approach provides insights for promoting hydrogen absorption and desorption of other metal hydrides.
