21. Biomaterials for Promoting Self-Healing of Bone Tissue
Sammanfattning : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. LÄS MER
22. Structure and Mechanical/Transport properties of Single and Multilayer Polyethylene-based Materials
Sammanfattning : The current study discusses the structure, mechanical and transport properties of polyethylene-based materials into two parts. The first part deals with the migration and chemical depletion of active substance such as insecticides from moulded polyethylene sheets. LÄS MER
23. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens
Sammanfattning : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. LÄS MER
24. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability
Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.

25. Platinum-free Electrocatalysts : Design, Synthesis, and Energy Applications
Sammanfattning : Pt is one of the most commonly used catalysts for green energy applications, such as fuel cells, electrolyzers, and dye-sensitized solar cells. Although enormous effort has been put into improving the catalytic activity and minimizing the usage of Pt in the catalysts, the low abundance and high price of Pt still limit the large-scale commercialization of green energy devices and facilities.
