Summary: In this study, Ag micro-alloying is utilized to improve the hydrogen storage properties of the Mg85Ni15 material. Dissolved Ag atoms in the partial Mg2Ni lattice transform the lamellar Mg-Mg2Ni eutectic into a fishbone Mg-Mg2Ni eutectic, significantly improving the thermodynamics and kinetics of de-/hydrogenation. The results show that the Mg85Ni14.8Ag0.2 alloy has a hydrogenation capacity of 1.8, 3.0, and 4.1 wt% at 50, 100, and 175 & DEG;C, respectively, and starts to decompose only at 178 & DEG;C. The addition of Ag reduces the activation energy for dehydrogenation and improves the hydrogen de-/absorption kinetics by creating unstable Ag-H bonds and increasing the lattice spacing.

Summary: In this study, Ag micro-alloying was used to improve the hydrogen storage properties of Mg85Ni15 material. The results showed significant improvements in the thermodynamics and kinetics of de-/hydrogenation, with lower activation energy and higher desorption temperature. The doping of Ag atoms in Mg2Ni lattice led to the formation of unstable Ag-H bonds, promoting the decomposition of MgH2. Additionally, the increased lattice spacing provided a wider channel for hydrogen transport, enhancing the hydrogen de-/absorption kinetics.

Summary: The introduction of chemical disorder by substitutional chemistry into ionic conductors is a common strategy to stabilize high-symmetric phases while maintaining ionic conductivity at lower temperatures. Hydride materials, especially Ba2-delta H3-2 delta X, show promising ionic conductivity below 300 degrees C, opening new directions in electrochemical use of hydrogen. The layered anion order in these materials, along with Schottky defects, helps suppress structural transitions and retain a highly symmetric lattice.

Summary: A series of carbon-encapsulated Ni nanoparticles deposited on carbon nanotubes (Ni@CNT) were prepared using a simple impregnation method and characterized by physicochemical methods. The catalytic performance of Ni@CNT was found to be strongly influenced by the Ni concentration, with samples containing 1% Ni showing the highest activity in model reactions. The study demonstrates that the facile fabrication of Ni@CNT produces efficient catalysts for the hydrogenation of organic compounds using molecular hydrogen, with the catalytic properties primarily associated with the carbon surface and enhanced by the Schwab effect.

Summary: The synthesis of diamond from superaligned multiwalled carbon nanotube films under high pressure and high temperature resulted in diamond with extreme mechanical anisotropy correlated with its microstructure. Molecular dynamics simulation revealed that dense twin boundaries significantly hindered dislocation motion under indentation in the direction perpendicular to the nanotwin bundles, while such resistance was weaker in the direction along the nanotwin bundles. The study verifies the hardening effect in diamond via nanostructuring and highlights the potential for further tuning mechanical properties through microstructure design.

Summary: In this study, Au nanoparticles were utilized for the growth of single-walled carbon nanotubes (SWCNTs) on porous Si3N4 grids through chemical vapor deposition. The produced SWCNTs had diameters in the range of 0.75-1.8 nm, and the majority of them exhibited large chiral angles. Density functional theory calculations explained the enrichment of large chiral angle SWCNTs in the product by considering the SWCNT-Au interface formation energy and the SWCNT growth kinetics.
