1. Influence of waxes on bitumen and asphalt concrete mixture performance
Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER
2. Fast isolation of proteins from bioreactors using affinity chromatography techniques
Sammanfattning : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. LÄS MER

4. Development and improvement of methods for characterization of HPLC stationary phases
Sammanfattning : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. LÄS MER
5. Superporous agarose a new material for chromatography
Sammanfattning : Agarose, the most commonly employed chromatography base material in industrial purification processes for biomolecules – proteins, has almost ideal properties. The major disadvantage of the agarose support is its poor mechanical strength which excludes its use in high speed separations where small particles are needed in order to achieve improved chromatographic efficiency.
