2. 1. Titanium Dioxide Photocatalysis in Biomaterials Applications

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

   Abstract : 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. READ MORE

4. 2. On Ca²+ incorporation and nanoporosity of titanium surfaces and the effect on implant performance

   Author : Victoria Fröjd; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implants; osseointegration; biofilms; oral mucosa;

   Abstract : Dentala implantat är en väletablerad behandling för att ersätta förlorade tänder med långsiktigt goda resultat. Det finns en uppsjö av implantat med olika ytor på marknaden och bakom dessa ligger stora forskningssatsningar. READ MORE

5. 3. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

   Author : Tamer Essam; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

   Abstract : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

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

   Author : Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Bioactive Surgical Implant Coatings with Optional Antibacterial Function

   Author : Mirjam Lilja; Maria Strømme; Håkan Engqvist; Håvard Haugen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroxyapatite; titanium dioxide; photocatalysis; antibacterial effect; antibiotic release; biomimetic coating; co-precipitation; tobramycin;

   Abstract : Device associated infections are a growing problem in the field of orthopaedics and dentistry. Bacteria adhering to implant surfaces and subsequent biofilm formation are challenging to treat with systemic administered antibiotics. READ MORE
