1. 31. Hemicelluloses and other Polysaccharides for Wood Adhesive Applications

   Författare :Emelie Norström; Eva Malmström; Orlando Rojas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The growing environmental awareness has led to an increased interest in bio-based polymers as replacement for fossil-based materials. The purpose of the work described in this thesis was to investigate the possibility of using hemicelluloses and other polysaccharides as replacement for fossil-based polymers in wood adhesives.

3. 32. Thiol-Ene CHemistry and Dopa-Functional Materials towards Biomedical Applications

   Författare :Kristina Olofsson; Anders Hult; Michael Malkoch; Anders Daugaard; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; DOPA; biomedical; UV; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Thiol-ene chemistry is versatile and efficient and can be used as a powerful tool in polymer synthesis. In this thesis, the concept of thiol-ene chemistry has been central, where it has been explored as a tool for the synthesis of well-defined hydrogels and dopa-functional materials towards biomedical applications; such as hydrogels, primers for adhesive fixation of bone fractures, self-healing gels, and micelles for drug-delivery.

4. 33. Enhancing UV protection of clear coated exterior wood by reactive UV absorber and epoxy functional vegetable oil

   Författare :Sara Olsson; Mats Johansson; Gilles Sèbe; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Since ancient times wood has played a large role in human activities, both in terms of fuel and for construction purposes. A drawback with wood in exterior applications is, however, its susceptibility to photo-initiated degradation, caused by radiation from the sun. LÄS MER

5. 34. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil

   Författare :Sara Olsson; Mats KG Johansson; Emma Östmark; Mats Westin; Philip Evans; Minna Hakkarainen; Peter Weissenborn; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UV-protaction; wood; clear coating; UV absorber; epoxy functionalized soybean oil; grafting;

   Sammanfattning : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

7. 35. Exploring Amphiphilic PEGMA-Based Architectures as Nanoparticles for Drug Delivery

   Författare :Christian Porsch; Eva Malmström Jonsson; Steve Rannard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Sammanfattning : Within the last decades, the stated potential of polymer constructs as drug delivery systems have challenged researchers to develop sophisticated polymers with tunable properties. The versatility of polymers makes them highly attractive to tailor nanoparticles (NPs) which fulfill the demands of effective drug delivery systems (DDS). LÄS MER
