1. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes
Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE

2. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology
Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied. The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE

3. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption
Abstract : The interest in new environmentally friendly cellulose‐based productshas increased tremendously over the last years. At the same time theSwedish forest industry faces new challenges in its strive to increase the utilization of cellulose fibers in high‐value end‐products. READ MORE

4. Interfacial behaviour of surfactants and enzymes: studies at model surfaces
Abstract : This thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. READ MORE

5. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface
Abstract : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.
