Summary: The anti-disproportionation properties of Zr0.8Ti0.2-xNbxCo alloys were improved by substituting Zr with Ti and Nb. The co-substitution also decreased the activation energy for hydrogen/deuterium desorption reactions. Furthermore, the Zr0.8Ti0.2-xNbxCo-deuterides exhibited superior anti-disproportionation properties compared to the corresponding hydrides.

Summary: Ball milling Mg-based alloys with transition metal compounds enhances their hydrogen storage performances. In this experiment, La1.7Y0.3Mg16Ni + x wt.% TiF3 (x = 0-10) alloys were prepared using mechanical milling technology. XRD, SEM, HRTEM, and granulometry were used to analyze the composition and microstructure. The addition of TiF3 improves the crystallinity, reduces particle and crystallite sizes, and enhances hydriding and dehydriding kinetics. Adding 7 wt% TiF3 decreases the dehydrogenation activation energy and improves the hydrogen absorption rate at low temperatures.

Summary: In this study, the hydrogen isotope storage properties of ZrCo alloy were improved by partially substituting Zr with Ti and Nb. Alloys of composition Zr0.8Ti0.2-xNbxCo (x = 0.05, 0.1, 0.15) were prepared and characterized to investigate the effect of Ti and Nb doping on hydrogen storage properties. XRD analysis confirmed the formation of the desired pure cubic phase in all synthesized alloys, similar to the ZrCo phase. The presence of a single plateau in the hydrogen desorption pressure-composition isotherms confirmed the single-step hydrogen absorption-desorption behavior in Zr0.8Ti0.2-xNbxCo alloys. The co-substitution of Ti and Nb had a significant impact on the anti-disproportionation properties of the ZrCo alloy under hydrogen-induced disproportionation conditions, making the Ti and Nb co-substituted quaternary alloys desirable for hydrogen isotope storage and delivery applications.

Summary: Graphene templated Ti-Ni-Fe nanoparticles (TieNieFe@Gr) exhibit excellent catalytic effect on the de/re-hydrogenation characteristics of MgH2, lowering the onset desorption temperature and improving cycling performance. Analysis suggests possible electronic exchange between the catalyst and Mg/MgH2. Anchoring on the graphene template prevents agglomeration that would be detrimental to cycling performance.

Summary: This study systematically investigated the effects of Sc/V/Ni substitution on the hydrogen diffusion and anti-disproportionation properties of ZrCo alloys and their hydrides through theoretical calculations. The results showed that doping V can improve hydrogen permeability and fast kinetics by reducing the migration barrier of absorbed H. However, Sc/Ni increased the migration barrier and V/Ni increased the formation energy of H in ZrCoH3 hydrides. These findings provide valuable insights for the design of high-performance ZrCo alloys.

Summary: After preparing the surface of AISI316 steel, Ni-Co-P coating layer was applied using the electroless method with different mole ratios of CoSO4/NiSO4+CoSO4. The coating rate, alloy elements composition, corrosion rate, and hardness of the coating layer were analyzed. The coating rate of the Ni-Co-P layer depends on the mole ratio of CoSO4/CoSO4+NiSO4, sodium hypophosphite concentration, bath temperature, bath pH, and plating time. The XRD pattern confirmed the presence of Ni-fcc and tetragonal Ni12P5 in the Ni-Co-P deposits, with the formation of Ni3P phase during annealing at 400℃ for 1 hour.

Summary: Ab initio calculations were performed on the Fe-doped ZrCo (110) surface to investigate the adsorption, dissociation, and diffusion of atomic and molecular hydrogen. The results show that while Fe doping facilitates H2 molecule dissociation, it hinders the diffusion of H atoms on the surface and into the bulk, leading to a decrease in hydrogen storage performance of ZrCo alloy.

Summary: A Mg96Y2Zn2 alloy with a high proportion of long period stacking ordered (LPSO) structure was prepared, and it formed a YH2 + Mg(Zn) composite after hydrogen ab/desorption, exhibiting lower desorption temperature and enhanced hydrogen storage capacity compared to pure MgH2. The hydrogenation process of the alloy was governed by one-dimensional diffusion rate of hydrogen atoms, while the dehydrogenation process was dominated by two-dimensional interface movement of the metal/hydride phases.

Summary: Ti/Al composite sheets were prepared using the cold rolling process, and the peel strength of the composite sheet was found to increase with the initial strength of aluminium. Higher initial aluminium strength leads to better deformation coordination between titanium and aluminium, resulting in improved performance of the composite sheet. The change in initial aluminium strength also affects the microstructure uniformity and the residue on the peeling surfaces.
