  2. 6. Theoretical Studies on the Molecular Mechanisms of Photo-Catalytic Reactions on TiO2 Surfaces

    Author : Yongfei Ji; Yi Luo; Annabella Selloni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TiO2; First-principles; photocatalysis; Kemi; Chemistry;

    Abstract : Photocatalysis is a promising technology that can effectively convert the solar energyinto sustainable green energy. However, theoretical studies on the molecular mechanisms of photocatalytic reactions are rare. READ MORE

  4. 7. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes

    Author : Cecilia Eriksson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; TiO2; surface roughness; oxide thickness; wettability; whole blood; inflammation; wound healing; platelets; PMN granulocytes; adhesion; activation; receptor expression; respiratory burst.;

    Abstract : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.

  6. 9. Photocatalysis for Indoor Air Cleaning : In situ FTIR and DFT Study of Acetaldehyde Photo-Oxidation on TiO2 and Sulfate-Modified TiO2

    Author : Bozhidar Stefanov; Lars Österlund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; acetaldehyde; crotonaldehyde; dimer; adsorption; DFT; FTIR; photocatalysis; micro-kinetic modeling; acid–base properties; surface functionalization; Solid State Physics; Fasta tillståndets fysik; Materialvetenskap; Materials Science;

    Abstract : Acetaldehyde is among the group of VOC’s causing the so-called "sick building" syndrome. WHO has estimated that this problem, related to the indoor air-quality, affects one third of all buildings worldwide. TiO2 is an attractive material for the photocatalytic removal of VOC’s in the indoor environment. READ MORE
