  1. 1. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Författare :Sham Mohammadi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Sammanfattning : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. LÄS MER

  3. 2. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents

    Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER

  4. 3. Bioactive Coatings and Antibacterial Approaches for Titanium Medical Implants

    Författare :Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioactivity; antibacterial; titanium; hydrogen peroxide; hydroxyapatite; biomaterial; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The aim of this thesis was to characterize and manufacture coatings and surfaces with antibacterial properties and retained or enhanced bioactivity and biocompatibility. The aim was also to study the optimal composition and parameters of mixtures for debridement of bacterial biofilms on titanium surfaces. LÄS MER

  7. 5. Titanium Dioxide Photocatalysis in Biomaterials Applications

    Författare :Yanling Cai; Ken Welch; Maria Strømme; Håkan Engqvist; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanium dioxide; photocatalysis; bioactivity; antibacterial effect; metabolic activity assay; biofilm; reactive oxygen species; disinfection kinetics; post-UV;

    Sammanfattning : Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. LÄS MER
