3. 17. Nanostructured Fuel Cell Catalysts

   Författare :Marie Gustavsson; Chalmers tekniska högskola; []
   Nyckelord :Nafion; thin film evaporation; model catalyst; electrocatalyst; acetic acid oxidation; oxygen reduction; colloidal lithography; PEMFC; screening; Pt; formaldehyde oxidation; methanol oxidation; nanofabrication; CO oxidation; polymer electrolyte; TiOx;

   Sammanfattning : A long term challenge for society is to develop sustainable energy systems to reduce the dependence on fossil fuels and to decrease air pollution. This requires new alternatives regarding the supply of energy and increased efficiency of the future energy systems. Fuel cell technology is one such possible alternative. LÄS MER

4. 18. Towards membrane engineering as a tool in cell factory design: A case study on acetic acid tolerance in Saccharomyces cerevisiae

   Författare :Lina Lindahl; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; butanol; inhibitors; lipidomics; Key words: Lignocellulose; Zygosaccharomyces bailii; molecular dynamics simulations; membrane permeability; carbon-14 uptake; ethanol; robustness;

   Sammanfattning : The sustainable production of fuels, chemicals, and materials using renewable resources is a necessity if we are to reduce our ecological footprint and the rate of climate change. Lignocellulosic biomass, the major constituent of plant cell walls, is a renewable raw material with great potential due to its high abundance. LÄS MER

5. 19. New markers of alcohol consumption : development and evaluation of the clinical use of carbohydrate-deficient transferrin in serum and 5-hydroxytryptophol in urine

   Författare :Annette Voltaire Carlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Alcohol drinking; 5-hydrogxytryptophol; 5-hydroxyindole-3-acetic acid; urine; human; ;

   Sammanfattning : Treatment of alcohol dependence and evaluation of treatment and research programs are often based on self-reports of the patients. Since the alcohol consumption pattern does not always relate to the reported behaviour there is a need for validation by reliable biochemical markers. LÄS MER

7. 20. Four carbon oxychemicals from renewable resources

   Författare :Adam Marschall Jaros; Christian Andersson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. LÄS MER
