21. Surface modification approaches of cellulose nanofibrils and their effect on dispersibility
Sammanfattning : In the strive to find and develop sustainable bio-based materials an increased interest for nanocellulosic materials as attractive alternatives has arisen during the past decades. This can be attributed to their abundant renewability, remarkable inherent mechanical properties and their capability to be chemically modified. LÄS MER
22. Synthesis of AcGGM Polysaccharide Hydrogels
Sammanfattning : Lignocellulosic biomass is believed to serve a prominent role in tomorrow’s sustainable energy and material development. Among the polysaccharide fractions of lignocellulosic biomass, the potential of hemicelluloses as a valuable material resource is increasingly recognized. LÄS MER
23. Wood Hemicelluloses - Fundamental Insights on Biological and Technical Properties
Sammanfattning : Hemicelluloses are a group of heterogeneous polysaccharides representing around 30 % of wood where the dominating types are xylans, glucomannans and xyloglucans. Hemicelluloses complex molecular structure makes it difficult to understand the relationship between structure and properties entirely, and their biological role is not yet fully verified. LÄS MER
24. Design of Cellulose-Based Materials via Sustainable and Scalable Processes
Sammanfattning : Plastic pollution is one of the most pressing environmental issues in today’s world. Addressing this problem calls for the development of environmentally friendly alternatives that would reduce the amount of persistent plastic waste. LÄS MER
25. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications
Sammanfattning : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. LÄS MER
