  1. 1. Functional Fibers for Biomedical and Thermal Management Applications

    Författare :Carl Zandén; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; microsystems; thermal management; thermal interface material; cell-scaffold interaction; metal matrix composite; fibers; microfluidic system; plasma surface modification; scaffold; electrospinning;

    Sammanfattning : This thesis explores the integration of electrospun polymeric structures in two fields; fibrous scaffolds as cell culture substrates for biomedical applications and fiber carrier networks in metal matrix polymer composites as thermal interface materials in microsystems. Electrospinning has been found to carry great potential for a range of future biomedical engineering applications. LÄS MER

  2. 2. Isolation and chemical modification of arabinoxylan and galactoglucomannan

    Författare :Linda Härdelin; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Tg; Films; Material properties; Isolation; Etherification; Modification; PEGylation; Hemicellulose;

    Sammanfattning : Today’s society is based on the use of fossil fuels, where oil is used as transportation fuel and as raw material in the petrochemical industry. Efforts are made to increase the use of bio-based materials, since oil is a non-renewable source and a greenhouse gas contributor. LÄS MER

  3. 3. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; Chalmers University of Technology; []
    Nyckelord :Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

  4. 4. Acoustic, Thermal and Non-thermal Dynamics in Condensed Matter Studied by Time-Resolved X-ray Diffraction

    Författare :Carl Ekström; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; Time-resolved; Ultrafast; Non-thermal melting; Thermal conductivity; Pressure wave; Opto-acoustic transducer; Fysicumarkivet A:2020:Ekström;

    Sammanfattning : The method of using short laser and X-ray pulses to investigate dynamics in materials (pump-probe) has been used for several decades. This thesis presents work that was carried out using these sources of light to reveal acoustic, thermal and non-thermal dynamics. LÄS MER

  5. 5. Chemical Modification of Cellulose Nanocrystals: Creating a Novel Toolbox Utilising the Overlooked Sulphate Surface Groups

    Författare :Karin Sjövold; Chalmers University of Technology; []
    Nyckelord :Composites; Scale-up; Dialkylamines; Cellulose nanocrystals; Azetidinium salts; Chemical modification; Thermal stability;

    Sammanfattning : The move towards a bio-based economy has created an increasing demand for renewable, sustainably produced materials. For future generations, it is crucial to develop economically, socially and environmentally sustainable materials and processes. LÄS MER
