  2. 11. Photocatalysis beyond conventional precious metal complexes

    Author : Rickard Lindroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Abstract : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. READ MORE

  4. 12. Synthesis and Characterization of Some Nanostructured Materials for Visible Light-driven Photo Processes

    Author : Rania Elhadi Adam; Omer Nour; Magnus Willander; Nicolas Martin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanoparticles; Nanocomposites; Heterostructures; Photocatalysis;

    Abstract : Nanostructured materials for visible light driven photo-processes such as photodegradation of organic pollutants and photoelectrochemical (PEC) water oxidation for hydrogen production are very attractive because of the positive impact on the environment. Metal oxides-based nanostructures are widely used in these photoprocesses due to their unique properties. READ MORE

  5. 13. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide

    Author : David Michael Langhammer; Lars Österlund; Tomas Edvinsson; Gunnar Niklasson; Günther Rupprechter; Uppsala universitet; []

    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

  6. 14. Antibacterial Strategies for Titanium Biomaterials

    Author : Erik Unosson; Ken Welch; Håkan Engqvist; Timo Närhi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; silver; biomaterial; antibacterial; photocatalysis; hydrogen peroxide; reactive oxygen species; combinatorial materials science; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

    Abstract : Titanium and titanium based alloys are widely used in dentistry and orthopedics to replace hard tissue and to mend broken bones. It has become a material of choice due to its low density, high strength, good biocompatibility and its capacity to integrate closely with the bone. READ MORE

  7. 15. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

    Author : Francesco Montecchio; Klas Engvall; Roberto Lanza; Ernest Blatchley III; KTH; []
