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. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques
Abstract : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. READ MORE

3. 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

4. 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

5. NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques
Abstract : The aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications.
