11. Hydrophobization of cellulose for bio-based materials
Sammanfattning : Cellulosa, vilken är huvudkomponenten i växter förekommer rikligt i naturen, både på land och i havet. Cellulosabaserade material har i tusentals år använts av människan för dagliga förnödenheter som bränsle och konstruktionsmaterial. Cellulosa isolerades först av den franske forskaren Anselme Payen 1838. LÄS MER
12. Enzyme catalysis towards bio-based UV-curable buildingblocks
Sammanfattning : Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can be done to develop more environmental methods for producing them. LÄS MER
13. Thiol−ene Coupling of Renewable Monomers : at the forefront of bio-based polymeric materials
Sammanfattning : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.

14. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective
Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER
15. Bio-based preparation of nanocellulose and functionalization using polyelectrolytes
Sammanfattning : Nanocellulosa, som kan utvinnas från skogsråvara, har de senaste åren fått mycket uppmärksamhet för sina intressanta egenskaper och breda användningsområde. Studierna i denna avhandling syftar till att vidga möjligheterna att använda nanocellulosa i olika applikationer. LÄS MER
