4. 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 : 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.

   Abstract : The properties of functional materials have been studied with density functional theory. The first type of materials that have been investigated is the so called diluted magnetic semiconductors. It is a new class of materials that could offer enhanced functionality by making use of spin in addition to the charge of the electron. READ MORE
