Summary: Li-Mg-N-B-H/ZrCoH3 composites were synthesized by ball milling under different atmospheres. The composite synthesized under hydrogen atmosphere displayed the best hydrogen storage properties. The microstructures and elemental distributions were characterized and it was found that Mg underwent in situ hydrogenation and ZrCoH3 particles were homogeneously distributed. The activation energy of the composite was calculated and found to be lower with the addition of ZrCoH3. The weakening of N-H bond was analyzed and discussed.

Summary: Impedance measurements on Mg-doped alumina ceramics showed a combination of oxide ion conductivity and p-type electronic conductivity depending on temperature and oxygen partial pressure. Co-doping with Mg and Si resulted in a reduction in oxide ion conductivity and p-type conductivity due to direct replacement of Al3+by Mg2+ and Si4+ ions.

Summary: A collaborative interface optimization strategy was used to prepare a metal-organic framework (MOF) derived heterostructure electrocatalyst (MXene@RuCo NPs), which showed excellent performance in electrocatalytic hydrogen/oxygen evolution reactions. The electrocatalyst exhibited low overpotentials and high current densities, thanks to the introduction of second active sites and the enhancement of the number of active sites by doped Ru. The heterogeneous interfaces of MXene/RuCo NPs in the catalysts also played a significant role in improving the charge transfer rate and reducing the energy barrier of the catalytic reaction.

Summary: Methamphetamine (Meth) is a highly addictive CNS stimulant, and effective treatment for Meth addiction is currently lacking. This study investigates the role of cell adhesion molecules (CAMs) in Meth addiction and specifically focuses on Contactin 1 (CNTN1). The findings suggest that CNTN1 expression in the nucleus accumbens (NAc) plays a crucial role in Meth-induced addiction, and the mechanism may involve the expression of synapse-associated proteins in the NAc. Silencing CNTN1 expression in the NAc can reverse Meth-induced conditioned place preference (CPP) and decrease the expression levels of NR2A, NR2B, and PSD95 in the NAc.

Summary: The deformation behaviors of a dual-phase Mg alloy containing α-Mg and 18R-LPSO phases were investigated in this study. The 18R phase, accounting for 11.3 vol.%, contributed to 23.0% of the overall alloy deformation. The coordinated twinning deformation of α-Mg matrix through the slip of basal dislocations and the kinking deformation of Mg slices induced by the 18R phase were observed during the early stage of deformation. At the end of deformation, a large number of T2-type stacking faults were generated, improving the ductility of the alloy. This work provides a novel strategy for designing high-strength and good ductility dual-phase Mg alloys.

Summary: The SnO2/Ti3C2Tx composite electrode is fabricated by dispersing sodiophilic SnO2 nanoparticles on 2D Ti3C2Tx, providing acceptor sites for Na+ to control vaporization and dendrite growth. The composite electrode exhibits smooth morphology, stable Coulombic efficiency, and long stable cycles, thanks to highly sodiophilic sites and the confinement effect. The full cells assembled with Na0.6MnO2 also show excellent rate performance and cycling performance. These findings demonstrate the effectiveness of the acceptor sites and confinement effect provided by the SnO2/Ti3C2Tx composite, offering additional design freedom for SMBs.

Summary: Surface regulation of electrocatalysts is crucial for improving alkaline hydrogen evolution reaction (HER) performance. In this study, transition metal-doped Ni3N nanosheets were prepared and studied for efficient alkaline HER. Experimental and computational characterization demonstrated the unique electronic structure and composition of the catalysts. The down-shifting of d-band center and transition metal doping facilitated the adsorption of water and significantly enhanced the alkaline HER performance. The V-doped Ni3N catalyst exhibited remarkable activity with low overpotential, suggesting a promising strategy for rational design of efficient HER electrocatalysts.

Summary: The effect of elastic tensile stress on the phase composition and structure of the rust layer formed on Q235 carbon steel in 5% NaCl salt spray was investigated. The results showed that the elastic tensile stress accelerated anodic dissolution, promoting the formation of -FeOOH. Different stress levels resulted in changes in the mass fractions of gamma-FeOOH, alpha-FeOOH, and Fe3O4/gamma-Fe2O3 in the rust layer. Additionally, the stress increased the thickness and decreased the compactness of the rust layer, enhancing its protective capability.

Summary: Mg-based hydrogen storage materials have attracted attention for their high hydrogen storage density, abundant resources, and environmental friendliness. However, challenges such as slow kinetics, high absorption/desorption temperature, and poor cycling stability hinder their large-scale use. Recent developments in alloys, nano-structure control, catalytic modification, and multiphase composites have made progress in addressing these challenges. Further improvements are needed in hydrogen storage capacity, adsorption/desorption temperature, reaction rate, and cycling life.
