1. Particle concentrations : analysis methods for urban runoff
Abstract : Urban runoff often contains high concentrations of particles. Pollutants that adsorbs to surfaces of particulate material will be transported to receiving waters or a sewage treatment plant. For the recipient, the particles in the runoff are a significant cause of water quality impairment. READ MORE

3. Enzyme immobilization in mesoporous silica
Abstract : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. READ MORE

4. Study and Modeling of the Reduction of Sulfur Dioxide, Nitrogen Oxides and Hydrogen Chloride by Dry Injection Technologies
Abstract : The potential and mechanism to reduce acid gases, such as SO2, NOx and HCl by dry Ca-based sorbents have been studied to improve the efficiencies of the process and sorbent utilization. Several natural limestones were tested for SO2 removal. Calcium conversion as high as 45% was achieved within 0.3 s at 1000°C, 1000 ppm SO2 and Ca/S=1. READ MORE

5. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets
Abstract : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. READ MORE
