1. 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

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. Organic Synthesis in Nonionic Microemulsions
Abstract : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. READ MORE

4. Lecithin-Based Microemulsions for Pharmaceutical use - Phase behavior and Solution Structure
Abstract : Microemulsions are thermodynamically stable, transparent solutions of water, oil and amphiphile(s). It is possible to incorporate large amounts of oil in microemulsions, which makes them interesting for use as a drug delivery vehicle for water insoluble drugs. A prerequisite for pharmaceutical use, however, is a low toxicity of the composition. READ MORE

5. Nanomaterials for high-temperature catalytic combustion
Abstract : Katalytisk förbränning är en lovande teknik för användning vid kraftgenerering, särskilt för gasturbiner. Genom att använda katalytisk förbränning kan man nå mycket låga emissioner av kväveoxider (NOX), kolmonoxid (CO) och oförbrända kolväten (UHC) samtidigt, vilket är svårt vid konventionell förbränning.
