2. 21. Preparation and Characterisation of Sputtered Titanium- and Zirconium Nitride Optical Films

   Author : Kent Andersson; Arne Roos; M. Georgson; Uppsala University Department of Technology Solid State Physics Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Multilayered interference coatings based on titanium- and zirconium nitride and designed for solar control have been prepared using reactive d c magnetron sputtering. Preparation effects and degradation mechanisms were investigated. It was shown that the quality of the nitride strongly depends on the degree of crystallinity in the underlying oxide. READ MORE

4. 22. Thermoelectric polymer-cellulose composite aerogels

   Author : Shaobo Han; Xavier Crispin; Simone Fabiano; Rachel Segalman; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Thermoelectric materials are scrutinized as energy materials and sensing materials. Indeed, they convert thermal energy into electrical energy. In addition, those materials are actively sensitive to a temperature modification through the generation of an electric signal. READ MORE

5. 23. New Methods in the growth of InP on Si and Regrowth of Semi-insulating InP for Photonic Devices

   Author : Wondwosen Tilahun Metaferia; Sebastian Lourdudoss; Eric Tournié; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis addresses new methods in the growth of indium phosphide on silicon for enabling silicon photonics and nano photonics as well as efficient and cost-effective solar cells. It also addresses the renewal of regrowth of semi-insulating indium phosphide for realizing buried heterostructure quantum cascade lasers with high power and wall plug efficiency for sensing applications.

6. 24. Durability evaluation of PEM fuel cell components

   Author : Live Mølmen; Peter Leisner; Lars Fast; Frode Seland; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Proton exchange membrane fuel cell; bipolar plate; corrosion; interfacial contact resistance; electrocatalysis; Polymermembranbränsleceller; bipolära plattor; korrosion; kontaktresistans; katalys;

   Abstract : Proton exchange membrane fuel cells (PEMFCs) are used to convert hydrogen and oxygen to electricity, heat, and water. There are no greenhouse gas emissions, given that the hydrogen is produced from renewable sources, such as water electrolysis from wind, hydro or solar energy. READ MORE

7. 25. Thermochromic VO2-based materials for smart windows : Progress towards applications in buildings

   Author : Yuxia Ji; Granqvist Claes G.; Niklasson Gunnar A.; Lars Österlund; Dimitra Vernardou; Uppsala universitet; []
   Keywords : Thermochromic; Vanadium dioxide; Smart windows; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Abstract : Vanadium dioxide is a well-known thermochromic material, whose optical properties can be varied reversibly in response to fluctuation of temperature. It is attractive in various fields due to its unique properties as well as its prospective applications. READ MORE
