  3. 2. Adsorption of Molecular Hydrogen on Cu, Pd and Ni Surfaces

    Författare :Krister Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron energy loss spectroscopy; nickel; molecular chemisorption; hydrogen; palladium; physisorption; photodesorption; copper;

    Sammanfattning : This thesis is devoted to spectroscopic studies of molecular hydrogen adsorbed on metal surfaces. Hydrogen is the simplest molecule available and is a very valuable model adsorbate. From a spectroscopic point of view there are also three easily accessible molecular isotopes, H2, HD and D2, with widely different masses. LÄS MER

  4. 3. High Temperature Corrosion in Fluidised Bed Environment

    Författare :Anna Nafari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; coatings; Ni and iron based alloys; HCl; SO2; loop seal; High temperature corrosion; erosion corrosion test rig; surface characterization and temperature gradient;

    Sammanfattning : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. LÄS MER

  5. 4. Structural investigations of some ternary metal hydrides

    Författare :Ewa Rönnebro; Gary Sandrock; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : This work was undertaken with the intention of describing the metal atom environment of hydrogen in a selection of ternary metal hydrides that could be of interest as hydrogen sorption materials. Mainly X-ray and neutron diffraction techniques were used for the purpose. LÄS MER
