1. Functional Fibers for Biomedical and Thermal Management Applications
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. Isolation and chemical modification of arabinoxylan and galactoglucomannan
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. Fungal degradation patterns and toxicity of furfurylated wood
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. Acoustic, Thermal and Non-thermal Dynamics in Condensed Matter Studied by Time-Resolved X-ray Diffraction
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. Chemical Modification of Cellulose Nanocrystals: Creating a Novel Toolbox Utilising the Overlooked Sulphate Surface Groups
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
