3. Colloidal fumed silica and soluble silicates — Interactions and microstructure
Abstract : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. READ MORE

4. Fate of Trace Elements in Thermochemical Conversion of Waste Fuels Using Oxygen Carriers
Abstract : The metals zinc, copper and lead are amongst the more abundant trace elements in waste fuels. The fate of these elements is important to study because they can affect the thermochemical conversion process and end up in ashes. READ MORE

5. Alkali-enhanced gasification of biomass : laboratory-scale experimental studies
Abstract : Gasification seeks to break carbonaceous materials into synthetic gas (CO+H2) which can be subsequently upgraded into valuable products. Thus gasification can be utilized to convert low grade biomass stocks into carbon-neutral chemicals heat and power. READ MORE
