1. Acid-base properties of and metal ion affinity for oxygen-delignified kraft pulps
Sammanfattning : .... LÄS MER
2. Synthesis and transformation of some low molecular weight carbohydrates
Sammanfattning : A one-step transformation of hydroxyl groups in carbohydrates to bromo groups is presented.The usefulness of ρ-methoxybenzyl as a protecting group of the anomeric center is examined. Reductive elimination by treatment of acetylated deoxyhalo sugar derivatives using zinc powder in ethanol containing acetic acid to give unsaturation is described. LÄS MER
3. Properties and performance of environmentally adapted synthetic esters
Sammanfattning : The lubricants of the future have to be more environmentally adapted, have a higher level of performance, and lower total life cycle cost (LCC) than commonly used lubricants today. Since we live on a planet with finite resources, we have to think about coming generations and work for a sustainable development in the field of tribology. LÄS MER
4. Tailoring of Biomaterials using Ionic Interactions : Synthesis, Characterization and Application
Sammanfattning : The interactions between polymers and components of biological systems are an important area of interest within the fields of tissue engineering, polymer chemistry, medicine and biomaterials. In order to create such a biomimetic material, it must show the inherent ability to reproduce or elicit a biological function. LÄS MER
5. Design and Development of Mineral Structure Specific Collectors in Flotation
Sammanfattning : The success of mineral flotation processes depends on the hydrophobization of the surface for the desired mineral particles whilst keeping, or making, all other minerals hydrophilic. This is achieved by adding several reagents to the flotation pulp to adsorb selectively at the mineral/water interface. LÄS MER
