Krishnan, G. (author), Kooi, B.J. (author), Palasantzas, G. (author), Pivak, Y. (author), Dam, B. (author)In this work we present a unique transmission electron microscopy study of the thermal stability of gas phase synthesized Mg nanoparticles, which have attracted strong interest as high capacity hydrogen storage materials. Indeed, Mg nanoparticles with a MgO shell ( ? 3?nm thick) annealed at 300?°C show evaporation, void formation, and void...journal article 2010
