1. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines
Sammanfattning : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.

2. On the way of making plants smell like moths - a synthetic biology approach
Sammanfattning : Moth caterpillars are major agricultural pests in many parts of the world. In general female moths attract male mates with their pheromone over long distance. Most of the described moth pheromones belong to the same class of chemical compounds, fatty acid derivatives that are produced de novo in the pheromone gland. LÄS MER
3. Synthesis of jojoba-like wax esters in metabolically engineered strains of Saccharomyces cerevisiae
Sammanfattning : Yeast has a long-standing tradition in human history as a production organism of choice. Besides being used for the production of fermented products like bread or beer, it has also been extensively explored for the production of proteins and chemicals. LÄS MER
4. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines
Sammanfattning : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. LÄS MER
5. Free radical mediated cellulose degradation
Sammanfattning : This thesis addresses the mechanisms involved in cellulosedegradation in general and Totally Chlorine Free (TCF) bleachingof pulp in particular. The thesis shows that the cellulosedegradation during high consistency ozone bleaching is explainedby free radical chain reactions. LÄS MER
