21. Swelling and Microstructure of Nanoplatelet Systems
Abstract : Many clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. READ MORE

22. Fundamental research on supercritical fluid extraction kinetics : From on-line measurements to inverse modeling
Abstract : Supercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. READ MORE

25. Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings
Abstract : Fuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. READ MORE
