2. Modification of microcapsules for controlled release
Abstract : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE

3. Exploring functionalization of colloidal silica for nanoparticle-stabilized emulsions
Abstract : The main objective of this thesis was to evaluate how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-dispersed silica nanoparticles were functionalized with hydrophilic and hydrophobic groups. READ MORE

5. Colloidal fumed silica and soluble silicates — Interactions and microstructure
Abstract : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. READ MORE
