   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Controlled release; geopolymer; sol-gel; opioid; oral administration; oral dosage form; implant; titanium; hydroxyapatite; infection; strontium carbonate; strontium; Functional materials; Funktionella material; Materials science; Teknisk materialvetenskap; Material physics with surface physics; Materialfysik med ytfysik; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

   Abstract : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. READ MORE

5. 3. Engineered core-shell nanoparticles for biomedical applications

   Author : Carmen Mihaela Vogt; Mamoun Muhammed; Alfonso Garcia-Bennett; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Functional materials; Funktionella material;

   Abstract : The necessity for synthesis of nanoparticles with well controlled size and morphology emerged with the development in recent years of novel advanced applications especially in biomedical related fields. These applications require nanoparticles with more complex architecture such as multifunctional nanoparticles (i.e. READ MORE

6. 4. 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

7. 5. Porous Amorphous Calcium Carbonate and Phosphate : Synthesis and Application

   Author : Rui Sun; Ocean Cheung; Maria Strømme; Ken Welch; Denis Gebauer; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous calcium carbonate; amorphous calcium phosphate; stabilization; crystallization; porous material; drug delivery; gas adsorption; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : The synthesis of porous amorphous calcium carbonate (ACC) and porous amorphous calcium phosphate (ACP) was developed in this thesis. Porous ACC with specific Brunauer–Emmett–Teller (BET) surface area of >350 m2/g was synthesized using a surfactant free approach. The high surface area of porous ACC was related to its nanostructure. READ MORE
