  1. 1. Phase Stability and Preparations of Oxide-Apatite Composites

    Författare :Erik Adolfsson; Bengt Kasemo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : In the preparation of bioactive composites containing hydroxyapatite, Ca5(PO4)3(OH), and an oxide it has been a problem to prevent the hydroxyapatite from decomposing in the sintering process. This is because H2O is evolved when hydroxyapatite is heated, implying that the occupied OH- positions in hydroxyapatite structure are partly replaced by vacancies and O2- ions. LÄS MER

  2. 2. In Search of the Holy Grail of Photoelectrochemistry : A Study of Thin Film Electrodes for Solar Hydrogen Generation

    Författare :Torbjörn Lindgren; Sten-Eric Lindquist; Claes-Göran Granqvist; Bengt Kasemo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; photoelectrochemistry; watersplitting; artificial photosynthesis; hydrogen; thin film; nanostructured; Fysik; Physics; Fysik;

    Sammanfattning : Hydrogen is a wanted energy carrier in a future society less dependent of fossil fuels. This thesis investigates the possibilities of using solar energy to convert water into hydrogen and oxygen, so called artificial photosynthesis. LÄS MER
