1. 21. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

   Författare :Oksana Zaushitsyna; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cells; Crosslinkers; PVA PEI; Immobilization; Biocatalysts; Biobased chemicals; Biotransformation; stress tolerance;

   Sammanfattning : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. LÄS MER

3. 22. Characterisation of thermally modified wood for use as component in biobased building materials

   Författare :Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.

4. 23. Lytic Polysaccharide MonoOxygenases; their role for lignocellulose depolymerization and production of (functional) biobased compounds

   Författare :Madhu Muraleedharan Nair; Paul Christakopoulos; Ulrika Rova; Mats Sandgren; Francisco Vilaplana; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Increased environmental concerns over petroleum-based products triggered the quest to find a sustainable alternative for fuels, chemicals etc. Lignocellulose biomass, due to its abundance, is considered as one of the most promising sustainable sources for the production of fuels and chemicals, while replacing the traditional petroleum resources.

5. 24. Exploring climate impacts of timber buildings : The effects from including non-traditional aspects in life cycle impact assessment

   Författare :Diego Peñaloza; Magnus Wålinder; Matty Janssen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment LCA ; timber buildings; biobased building materials; low-energy buildings; forest products; climate impact assessment; biogenic emissions; carbon storage; timing of emissions; Industrial Ecology; Industriell ekologi; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : There is an urgency within the building sector to reduce its greenhouse gas emissions and mitigate climate change. An increased proportion of biobased building materials in construction is a potential measure to reduce these emissions. LÄS MER

7. 25. Angular dynamics of non-spherical particles in linear flows related to production of biobased materials

   Författare :Tomas Rosén; Fredrik Lundell; Daniel Söderberg; Minh Do-Quang; Jason E. Butler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-linear dynamics; rotary diffusion; characterization techniques;

   Sammanfattning : Dispersed particle flows are encountered in many biological, geophysical but also in industrial situations, e.g. during processing of materials. In these flows, the particles usually are non-spherical and their angular dynamics play a crucial role for the final material properties. LÄS MER
