  1. 1. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

    Author : Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
    Keywords : Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

    Abstract : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.

  2. 2. Hunting Hydrogen : Structure-property relations in High Entropy Alloy-based metal hydrides

    Author : Gustav Ek; Martin Sahlberg; Ulrich Häussermann; William I.F. David; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hydrogen; metal-hydride; High Entropy Alloy; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Metal hydrides have many uses when switching the energy system from fossil fuels to renewable sources, such as rechargeable batteries, hydrogen storage, hydrogen compression and thermal storage. State of the art materials for these applications such as LaNi5 and TiFe, however, suffer certain limitations such as degradation during repeated hydrogen cycling and harsh activation conditions for initial hydrogen uptake, promoting the need for novel materials.
