  1. 1. 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. 2. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Författare :Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wood board industry; chamber methods; dynamic microchamber DMC ; bio-based adhesives; lignosulfonates; supercritical water hydrolyzed lignin; crosslinkers; fibreboards; particleboards; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

  4. 3. Synthesis and modifications of materials for separation science

    Författare :Anna Nordborg; Knut Irgum; Michael Lämmerhofer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; material synthesis; monolith; surface modification; telomer; “grafting to”; gradient polymer elution; chromatography; Chemistry; Kemi;

    Sammanfattning : This thesis deals with the preparation of materials for use in separation science and their surface modification by grafting. The overall aim is the preparation of diverse materials by combination of a set of developed tools. LÄS MER

  5. 4. Amino acid sequence and side chain specific synthetic receptors targeting protein phosphorylation

    Författare :Anil Incel; Frank Kjeldsen; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; imprinted polymers; synthetic receptors; PTM; phosphorylation; enrichment; diagnosis;

    Sammanfattning : Antibodies have become a critical component of many diagnostic assays and are used for therapeutic purposes. Nevertheless they often fail to meet the strict performance demands raised in industry and in the clinic (e.g. stability, reproducibility, selectivity, affinity). LÄS MER

  7. 5. Studies on the thermal degradation of thermosetting polyimides and their composites

    Författare :Valeri Petkov; Patrik Fernberg; Guan Gong; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer composites; Polyimide; Thermal oxidative degradation; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : The thesis contains a background and reflections section, an introduction, and three appended articles. The first section is reserved for some of the background and basics on polymers and polymer composites and a discussion on their effect on our everyday lives. The introduction gives a brief recap of the project. LÄS MER
