1. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems
Abstract : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. READ MORE

2. Water-in-diesel emulsion and microemulsion fuels -The effect of water on emission levels
Abstract : Water-in-diesel emulsions are known as environmentally favourable alternatives to conventional diesel fuel. Introducing water into the combustion results in reduced emissions of the health hazardous components nitrogen oxide (NOx) and particulate matter (PM). The concept of using emulsions is advantageous as it is easy to replace regular diesel. READ MORE

3. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions
Abstract : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. READ MORE

4. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems
Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE

5. Diffusion in cationic vesicle and micellar solutions- a NMR study
Abstract : Double tailed cationic surfactants are the active component in softeners. In the beginning of the 90s the active component in softener formulations was changed from a hydrolytically stable dialkyl dimethyl ammonium chloride (dialkyl quat) to a cleavable and biodegradable product containing ester groups in the alkyl chains (dialkyl ester quat).
