1. 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

2. Biobased and biodegradable binders for paper and nonwoven
Abstract : Nonwovens are textile-like materials with similarities close to paper. One significant sector where nonwovens are used is for single-use products such as wet wipes and hygiene products. With an increasing global population, the manufacturing and use of nonwovens have grown significantly. READ MORE

3. Wood hydrolysates- New concepts in renewable material design
Abstract : Wood hydrolysates (WHs) are biomasses obtained in processes involving hydrothermal treatments of wood. WHs are rich in hemicelluloses and lignin. Instead of complicated extraction processes, such as precipitation, or extensive purification, this work utilizes the crude WHs. READ MORE

4. 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

5. Immobilizing catalysts on textiles : case of zerovalent iron and glucose oxidase enzyme
Abstract : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. READ MORE
