1. Stability and sorption capacity of montmorillonite colloids : Investigation of size fractional differences and effects of γ-irradiation
Abstract : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. READ MORE

2. Exploring Biopolymer-Clay Nanocomposite Materials by Molecular Modelling
Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

3. Evaluation of the Tactoid Formation in Clay Systems
Abstract : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. READ MORE

4. Electrostatically Driven Structure Formation in Clay Dispersions
Abstract : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. READ MORE

5. Biodegradable Blends and Nanocomposite Films with Amylopectin, Poly(lactic acid) and Chitosan Matrices
Abstract : Användningan av engångsförpackningar har ökat kraftigt de senaste åren. Den absolut största delen av dessa förpackningar tillverkars av oljebaserade plaster såsom polyetylen (PE) och polypropylen (PP). Dessa har även en oerhört lång nedbrytningstid, vilket gör det viktigt att finna mer miljövänliga alternativ. READ MORE
