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

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

    Abstract : 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. READ MORE

    Abstract : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. READ MORE

  7. 10. Fabrication of inverse opal oxide structures for efficient light harvesting

    Author : Delphine Lebrun; Lars Österlund; Gunnar Niklasson; Vassilios Kapaklis; Herman Högström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic; inverse opal; metal oxide; opal; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Artificial opals are self-assembled face centered cubic (fcc) structures of  spherically shaped beads, which interesting applications as photonic band gap materials. Inverse opals are photonic crystals consisting of fcc paced voids of a low refractive index material imbedded in a high refractive index material. READ MORE
