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

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

   Abstract : 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. READ MORE

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

   Author : Linda Härdelin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tg; Films; Material properties; Isolation; Etherification; Modification; PEGylation; Hemicellulose;

   Abstract : 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. READ MORE

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

   Author : Annica Pilgård; RISE; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

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