Summary: In this study, the authors demonstrate how the fast reaction rate activates charge redistribution in manganese hexacyanomanganates, which helps alleviate the strong Jahn-Teller effect of high-spin Mn(III) by solving the unequal number of electrons in e(g) orbitals. As a result, the dissolution of Mn is effectively suppressed, leading to improved long-term cyclability in an aqueous electrolyte.

Summary: In this article, a novel applicator is developed to efficiently insert dissolving microneedle patches into the skin with optimized force and velocity. This applicator is cost-competitive and easy to use with thumb-force operation. The study shows that the microneedle and applicator system can generate significantly higher antibody levels compared to intramuscular injection when using a model antigen.

Summary: A novel composite oxide carrier doped by hetematoms was developed for the selective and stable production of C-2(+) hydrocarbons from methane in chemical looping oxidative coupling. Doping with Na improved the surface O- and Mn2+/Mn3+ species content, leading to higher C-2(+) selectivity and yield. Co-doping with W stabilized surface Na species, resulting in stable performance.

Summary: A new isoreticular structure, SNNU-Bai67, with highly selective adsorption for C2 hydrocarbons over CH4 was successfully synthesized by modifying VNU-18. The substitution of OH- with Cl- improved the adsorption uptake values of C2 hydrocarbons while maintaining nearly the same selectivity for C2 hydrocarbons/CH4, potentially due to enhanced interactions between gas molecules and the framework.

Summary: This study examines the solar thermo-catalytic methane decomposition for hydrogen and C-2-hydrocarbons production. By using a two-step process, methane is decomposed into C-2-hydrocarbons and hydrogen at high temperatures, followed by the decomposition of C-2-hydrocarbons into solid carbon and hydrogen at lower temperatures. Experimental results show that adding a catalyst significantly improves the yield of C2H2 without reducing the conversion of methane.
