   Author : Johan Forsgren; Håkan Engqvist; Strømme Maria; Susanne Bredenberg; Pentti Tengvall; Uppsala universitet; []
   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

4. 2. Structural and Electrochemical Properties of Functionalized Nanocellulose Materials and Their Biocompatibility

   Author : Daniel O Carlsson; Maria Strømme; Leif Nyholm; Albert Mihranyan; Eva Malmström Jonsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose; nanofibrillated cellulose; Cladophora cellulose; polypyrrole; TEMPO-mediated oxidation; composite; porosity; cytocompatibility; blood compatibility; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : Nanocellulose has received considerable interest during the last decade because it is renewable and biodegradable, and has excellent mechanical properties, nanoscale dimensions and wide functionalization possibilities. It is considered to be a unique and versatile platform on which new functional materials can be based. READ MORE

5. 3. Virus retentive filter paper for processing of plasma-derived proteins

   Author : Lulu Wu; Albert Mihranyan; Margareta Krabbe; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma-derived biologics; human serum albumin; human plasma-derived immunoglobulin; virus removal filtration; Cladophora cellulose; quality control; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : The studies in the present thesis explored the feasibility of using nanocellulose-based filters in virus removal filtration of plasma-derived proteins. In Paper I, two-step nanofiltration of commercially available human serum albumin (HSA) product, which was diluted to 10 g L-1 by phosphate buffer saline (PBS) and adjusted pH to 7.

6. 4. New insights into principles of scaffolds design for bone application

   Author : Hongji Yan; Tim Bowden; Hong Qian; Martijn van Griensven; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chondroitin sulfate; hyaluronic acid; pH; cross-linking chemistry; bone morphogenetic protein; lithium; mesenchymal stem cell; in vivo.; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : This thesis presents deeper insights into bone applicable biomaterials’ design. Poor affinity of BMP-2 towards scaffolds required supra-physiological dose administration. Though molecules containing sulfate could sustain BMP-2 release, side effects occurred due to BMP-2 supra-dose, or these sulfate-containing biomolecules. 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
