3. 27. Lignin-carbohydrate complexes: Model compounds synthesis

   Författare :Filip Nylander; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lignin-carbohydrate complex; lignin model compounds; lignocellulose;

   Sammanfattning : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.

4. 28. Governing Decarbonisation : The State and the New Politics of Climate Change

   Författare :Roger Hildingsson; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate politics; the environmental state; decarbonisation; low-carbon transition; energy transformation; authoritative steering; enabling; orchestrating; Sweden;

   Sammanfattning : This dissertation examines the “new climate politics of decarbonisation” and the role of the state as a site for progressive climate action. This new politics concerns transformative social change aimed at moving society away from its current dependence on fossil carbon energy. LÄS MER

5. 29. Process development for combined pentose and hexose fermentation

   Författare :Fredrik Nielsen; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Lignocellulose; Xylose fermentation; Co-fermentation; Process design; Agricultural residues; Saccharomyces cerevisiae;

   Sammanfattning : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.

7. 30. Colloidal synthesis of metal nanoparticles

   Författare :Anna Pekkari; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inline quality control; palladium; gold; stabilizers; NO2 reduction; core-shell; colloidal synthesis; copper; reduction kinetics; platinum; nanoparticles; segmented flow; nanocube; flow chemistry;

   Sammanfattning : Metal nanoparticles (NPs) are central in a wide range of industrial areas including catalytic and biomedical applications. Due to their interesting physical properties, the demand of these precious materials is steadily increasing, which has created a need for the development of effective and high-performing NPs. LÄS MER
