1. Nuclear magnetic resonance studies of water self-diffusion in porous systems
Sammanfattning : Proton nuclear magnetic resonance (NMR) was used to study the self-diffusion of water in porous systems that respond to a change in water content in order to elucidate the porous structure and the properties of the confined water. In the carbohydrate systems cellulose fibers and starch granules, water is free to move throughout the porous objects, albeit with a rate reduced from the value of the bulk liquid, The reduction is related to the tortuosity of the pore space filled by water.

2. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions
Sammanfattning : 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. LÄS MER
3. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies
Sammanfattning : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. LÄS MER
4. Water-in-diesel emulsion and microemulsion fuels -The effect of water on emission levels
Sammanfattning : 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. LÄS MER
