    Sammanfattning : Nanostructured titania is of great interest for a variety of energy and environmental applications, including conversion of solar energy, for energy storage systems and removal of organic pollutants in water and air. Titania is composed of earth abundant elements, it is environmentally friendly and chemically stable which makes it an attractive material to utilize. LÄS MER

  5. 4. Titanium Oxide and Bone Anchorage: Role of the Complement System, and Delivery of Osteoporosis Drugs from Mesoporous TiO2

    Författare :Necati Harmankaya; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titania; complement; photocatalysis; ovariectomy; alendronate; raloxifene;

    Sammanfattning : The clinical success of bone implants of titanium (Ti) is largely ascribed to the biological performance and the physicochemical properties of the outermost titanium(IV)dioxide (TiO2) layer. Several advancements have been done on TiO2 in order to optimize its healing and anchorage to bone, and there is a need for further understanding and control of the molecular reactions preceding long-term osseointegration.
