1. 11. Thin films of polyfluorene:fullerene blends - Morphology and its role in solar cell performance

   Författare :Cecilia Björström Svanström; Ellen Moons; Jean Manca; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Solar Cells; Polymer Blends; Morphology; Polyfluorene; PCBM; AFM; SIMS; Spin-Coating; Surface Directed Spinodal Decomposition; Physics; Fysik; Physics; Fysik;

   Sammanfattning : The sun provides us daily with large quantities of energy in the form of light. With the world’s increasing demand of electrical energy the prospect of converting this solar light into electricity is highly tempting. In the strive towards mass-production and low cost solar cells, new types of solar cells are being developed, e.g. LÄS MER

3. 12. Rhodium diesel-reforming catalysts for fuel cell applications

   Författare :Xanthias Karatzas; Lars J. Pettersson; James Spivey; KTH; []

   Sammanfattning : Heavy-duty diesel truck engines are routinely idled at standstill to provide cab heating or air conditioning, and in addition to supply electricity to comfort units such as radio and TV. Idling is an inefficient and unfavorable process resulting in increased fuel consumption, increased emissions, shortened engine life, impaired driver rest and health, and elevated noise. LÄS MER

4. 13. Expanded knowledge on silk assembly for development of bioactive silk coatings

   Författare :Linnea Nilebäck; My Hedhammar; Renko de Vries; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant spider silk; Self-assembly; Biomaterial; Implant coating; Functionalization; Multi-functional; Bioactive; Cell culture scaffold; Antibacterial; Bioteknologi; Biotechnology;

   Sammanfattning : Silk is a fascinating natural material made from proteins that self-assemble through structural rearrangements into one of the toughest materials known. As silk is protein-based, durable and elastic, it has many features that makes it suitable as a scaffold material for tissue engineering. LÄS MER

5. 14. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

   Författare :Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. LÄS MER

7. 15. Electrochemically nanostructured electrodes for Li-ion microbatteries

   Författare :David Rehnlund; Leif Nyholm; Reiner Lomoth; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrodeposition; 3D; Li-ion microbatteries; thin films;

   Sammanfattning : Electrodeposition is a promising technique for fabricating complex nanostructures and coating these with suitable thin films of active materials. The research presented in this thesis aims at the development of new electro- chemical methods for the synthesis of nanostructured electrodes suitable for Li-ion microbatteries. LÄS MER
