  2. 6. Photocatalytic TiO2 thin films for air cleaning : Effect of facet orientation, chemical functionalization, and reaction conditions

    Author : Bozhidar Stefanov; Lars Österlund; Gunnar Niklasson; Claes-Göran Granqvist; Peter Christian Kjærgaard Vesborg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; titanium dioxide; photocatalysis; thin films; surface functionallization; acetaldehyde; indoor air cleaning; sputter deposition; crystallographic modifications; preferential orientation; self-cleaning surfaces; Teknisk fysik med inriktning mot fasta tillståndets fysik; Engineering Science with specialization in Solid State Physics;

    Abstract : Poor indoor air quality is a source of adverse health effects. TiO2 coatings deposited on well-illuminated surfaces, such as window panes, can be used to fully mineralize indoor air pollutants by photocatalysis. READ MORE

  4. 7. Titania Nanoscale Films and Surfaces : Surface Science Investigation of Structure and Properties

    Author : Davide Ragazzon; Anders Sandell; Anne Borg; Jason F. Weaver; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photoelectron spectroscopy; PES; XPS; scanning tunneling microscopy; STM; titania; titanium oxide; TiO2; Au 111 ; gold; water; H2O; rutile;

    Abstract : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). READ MORE

  5. 8. On titanium release from dental implants and the inflammatory response

    Author : Mattias Pettersson; Margareta Molin Thorén; Anders Johansson; Ann Wennerberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; inflammation; dental implants; peri-implantitis; odontologi; Odontology;

    Abstract : In dentistry, dental implants have become a standard treatment for single tooth loss and partial and total edentulism since their introduction by P-I Brånemark in the 1960s. Long-term follow-up studies have shown that dental implantation is a predictable treatment, with an overall implant survival over ninety-five percent. READ MORE

  6. 9. Recovery and reuse of TiO2 and other pigments from paint waste

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide; Paint Waste; Recovery; Pyrolysis;

    Abstract : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. READ MORE

  7. 10. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE
