Metal boride nanostructures have shown significant promise for hydrogen storage applications. However, the synthesis of nanoscale metal boride particles is challenging because of their high surface energy, strong inter‐ and intraplanar bonding, and difficult‐to‐control surface termination. Here, it is demonstrated that mechanochemical exfoliation of magnesium diboride in zirconia produces 3–4 nm ultrathin...
Design of interfaces with thermodynamic and kinetic specificity is of great importance for hydrogen storage from both an applied and fundamental perspective. Here, in order to destabilize the metal hydride and protect the dehydrogenated products from oxidizing, a unique core‐shell structure of porous Mg(BH4)2‐based framework with a thin layer (no more than 5 nm) of MgCl2 additives on the surface,...
The role of polymer dynamics on nanocrystal growth in the synthesis of composites is studied with Mg nanocrystal‐poly(methyl methacrylate) (PMMA) as a model system by J. J. Urban and co‐workers in article number 1602572. The polymer conformation can be controlled by varying the reaction conditions that maneuver in‐situ nanocrystal growth in the composite. The concomitant change in functional properties...
The role of polymer dynamics on nanocrystal growth in the synthesis of composites is studied using a well‐controlled Mg nanocrystal–poly(methyl methacrylate) (PMMA) system. The in situ formation of Mg nanocrystals in PMMA is examined under different conditions, varying polymer conformation in solution. The change of hydrogen sorption properties of Mg is investigated to assess functional impacts of...
