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

Filippi, M. (author), Rector, J.H. (author), Gremaud, R. (author), Van Setten, M.J. (author), Dam, B. (author)We report the preparation of sodium alanate, a promising hydrogen storage material, in a thin film form using cosputtering in a reactive atmosphere of atomic hydrogen. We study the phase formation and distribution, and the hydrogen desorption, with a combination of optical and infrared transmission spectroscopy. We show that the hydrogen...journal article 2009
