  1. 1. Infrared spectroscopy studies of adsorption and photochemistry on TiO2 surfaces : From single crystals to nanostructured materials

    Författare :Andreas Mattsson; Lars Österlund; Per-Anders Carlsson; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : TiO2 based photocatalysis is a green nanotechnology that can be used for removal of pollutants from water and air, as well as making synthetic fuels from water and carbon dioxide. Said photocatalysis has received major research interests during the last decades. LÄS MER

  3. 2. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles

    Författare :David Langhammer; Lars Österlund; Anders Sandell; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. LÄS MER

  4. 3. Micromechanics of oxides - From complex scales to single crystals

    Författare :Anand Harihara Subramonia Iyer; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Cr2O3; oxide scales; micromechanical testing; fracture; electron microscopy;

    Sammanfattning : Protective oxide scales shield high temperature materials from corrosion, thus ensuring safety and long material life under adverse operating conditions. Cracking and spallation of such scales can lead to fatigue crack initiation and expose the material to further oxidation. LÄS MER

  5. 4. Tungstate Scintillators Growth, Structures and Properties

    Författare :Magnus Åsberg Dahlborg; Chalmers University of Technology; []
    Nyckelord :scintillators; single crystals; ZnWO4; HgWO4; neutron powder diffraction; X-ray diffraction; CdWO4; flux growth; tungstates;

    Sammanfattning : Tungstate crystals are well-known scintillators, which can be used as detector material for high-energy radiation and are often chosen as references in measurements on new luminescent materials. For measurements of excitation and relaxation properties, single crystals are desirable. LÄS MER
