Inside Cover: Porous and Dense Magnesium Borohydride Frameworks: Synthesis, Stability, and Reversible Absorption of Guest Species (Angew. Chem. Int. Ed. 47/2011)
Thor, god of thunder is shown as a symbol of all the alternative, environmentally friendly energy sources, some of which are shown in the background. In their Communication on page 11 162 ff., Y. Filinchuk, T. R. Jensen et al. report a highly porous form of Mg(BH4)2 that can reversibly absorb guest species and thus act as a reservoir for hydrogen storage. This material has an open-framework structure that is similar to those of metal–organic frameworks.
