Summary: To enhance the hydrogen storage performance of Mg-rich alloys, element Sc is introduced into Mg-Y-Zn alloy, which effectively enhances the dehydrogenation kinetics and facilitates the decomposition of YH3. Sc-doping weakens H2 sorption but ensures H atom diffusion in the Mg matrix. Sc substitution makes it difficult for hydrogen to diffuse deeper into the samples, resulting in a large ratio of unhydrided Mg.

Summary: In this study, a new sandwich configuration reaction bed of metal hydride-thermochemical material (MH-TCM) system was proposed and its excellent hydrogen and thermal storage performance was numerically validated. The results showed that the sandwich reaction bed had faster transfer and reaction rate, resulting in a 61.1% reduction in hydrogen storage time. Increasing the thermal conductivity of the reaction beds further reduced the storage time, while improving the hydrogen inflation pressure enhanced heat transfer and hydrogen absorption rates.

Summary: This paper proposes a multi-layer cylindrical reactor with metal hydride (MH) and phase change material (PCM) alternately arranged to solve the heat management problem of MH. Through numerical modeling and validation, it is found that the reactor using lithium nitrate trihydrate as PCM material has the best performance, reducing reactor volume while slightly delaying absorption time. The specific capacity rate (SCR) and volumetric capacity rate (VCR) of the proposed reactor are 3.4 and 3.12 times higher than the corresponding values in literature.

Summary: In this study, a two-dimensional Ti3CN MXene was synthesized and added to the Li-Mg-B-H composite, resulting in a reduction in the dehydrogenation temperature and induction period of the composite. The reversible capacity and capacity retention ratio of the composite were maintained at high levels. Micro-structure studies revealed the transformation of Ti3CN into highly-dispersed nano-TiB2, which acted as an active catalyst to improve the kinetics and reversibility of the composite. This research provides insights into the role of MXene in tailoring the hydrogen storage properties of metal borohydride-based composites.

Summary: The storage of hydrogen in a compact, safe and cost-effective manner is crucial for a more sustainable society. Magnesium hydride (MgH2) has attracted attention as a hydrogen carrier but its practical use is limited due to high temperatures and slow kinetics. Catalysis plays a crucial role in enhancing hydrogen cycling kinetics, and research has focused on designing and optimizing catalysts for Mg/MgH2.

Summary: This review discusses the development and current state of Cu-rich Cu-Cr-Nb alloys, specifically focusing on GRCop-84 and GRCop-42. Recent advancements in additive manufacturing have boosted interest in GRCop alloys, with full-scale hardware and hot-fire tests being conducted, but further research on structure-property relationships is needed. Comparisons to other high-heat-flux Cu alloys are made, and future prospects and advantages provided by additive manufacturing for GRCop alloys are assessed.

Summary: Accurate phase fraction analysis is crucial for microstructural characterization of alloys. Commonly available XRD and EBSD were used to analyze 17-4 precipitation-hardening martensitic stainless steel, indicating challenges in quantifying phase fraction in AM alloys. The study suggests that techniques such as synchrotron-based high-energy X-ray diffraction may be required for a proper understanding of these materials.

Summary: The recent development of multicomponent, high-entropy oxides (HEOs) has opened up possibilities for exploring ceramics with diverse compositions and structures. These HEOs can be custom-designed for various applications, thanks to their single-phase (SP) structure. Researchers have been investigating the phase transitions in HEOs to understand the factors driving the transition from multiphase to single-phase structure. This review emphasizes the role of entropy stabilization and the effects of high-entropic lattice disorder on these phase transitions.
