1. Structure and Dynamics of Silica Dispersions and Gels
Abstract : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The first project concern the gelation of water glass, also known as alkaline sodium silicate solutions.

2. 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

4. The influence of high temperature on the discoloration and degradation of carbohydrates and on hydrogen peroxide bleaching of spruce TMP
Abstract : When processing wood to obtain pulp, the fibers are subjected to high temperatureat moisture levels and to the influence of metal ions. Many process developmentshave resulted in utilization of higher temperatures that induce chemical reactionsin the wood fibers. This thesis deals with some aspects of using high temperaturesin pulping processes. READ MORE
