1. Nanocomposites made from nanoporous cellulose fibre
Sammanfattning : This thesis explores how to use the dry nanoporous structure of cellulosic fibres in new types of composite materials. A large effort was also given on how to correctly characterize the structure of fibres where the wet structure has been preserved also in the dry state. LÄS MER
2. Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation
Sammanfattning : The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. LÄS MER
3. Surface Modification of Nanocellulose towards Composite Applications
Sammanfattning : Nanocelluloses have attracted great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of this work was to investigate new strategies for surface modification and functionalization of nanocelluloses and their subsequent incorporation in polymer-host matrices. LÄS MER
4. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption for Biocomposite Applications
Sammanfattning : There is an increasing interest to replace fossil-based materials with renewable alternatives. Cellulose fibers/nanofibrils (CNF) are sustainable options since they are biobased and biodegradable. In addition, they combine low weight with high strength; making them suitable to, for example, reinforce composites. LÄS MER
5. Spatial Tissue Mapping on Joint Biopsies from Arthritis Patients
Sammanfattning : Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that mainly affects joints, causing discomfort and pain that severely reduces the life quality of affected individuals. Its etiology is largely unknown, but some pathophysiological mechanisms have been identified. LÄS MER
