    Sammanfattning : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. LÄS MER

  4. 3. Synthesis and Characterisation of Carbide Derived Carbons

    Författare :Sigita Urbonaite; Gunnar Svensson; Mats Johnsson; Rik Brydson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbide derived carbons; Gas adsorption; EELS; Raman; Porous carbons; Chemistry; Kemi; strukturkemi; Structural Chemistry;

    Sammanfattning : Carbide derived carbons (CDCs) have been synthesised through chlorination of VC, TiC, WC, TaC, NbC, HfC and ZrC at different temperatures. The aim of the investigation was to systematically study changes of structural and adsorption properties depending on the synthesis conditions. LÄS MER
