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

3. Synthesis and characterisation of thermoset-layered silicate nanocomposites
Abstract : Thermoset-layered silicate nanocomposites are materials reinforced on a molecular scale by 1 nm-thick silicate layers of high aspect ratio dispersed in a thermoset matrix. These new materials were synthesised from unsaturated polyester and several epoxy resins (DGEBA/diamines and TGDDM/DDS) using two different approaches. READ MORE

4. A vibrational spectroscopy study of the growth of silicate-1 films on noble metal surfaces
Abstract : The main objective of this thesis was to acquire a better understanding of the mechanisms involved in the preparation of Silicalite-1 films in general and on gold surfaces in particular. Molecular sieve films on gold surfaces were prepared using the seed film method. READ MORE

5. Redox reactions and structure - properties relations in mixed alkali/alkaline earth glasses : The role of antimony oxides during the fining process- A structural study of copper(I) and copper(II)
Abstract : It is important to optimize glass compositions for their specific purpose but also for the efficiency of the production process, the manufacturing of glass. This will be beneficial economically and environmentally. READ MORE
