1. Macromolecular synthesis of functional degradable aliphatic polyesters and porous scaffold design
Sammanfattning : There is an increasing demand for new materials in biomedical applications with material properties that are highly specific for each application area. The search for new materials requires the creation of materials with suitable mechanical properties, functionalities, three-dimensional structures and a controlled degradation profile. LÄS MER
2. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications
Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER
3. Suberin based polyesters
Sammanfattning : In the wish to replace oil-based chemicals and materials with such based on biodegradable and renewable resources, this work has been performed. In a biorefinary concept, waste birch bark from paper pulp mills and timber production has been evaluated as a potential source for polyesters. LÄS MER
4. Structure and Dynamics of Silica Dispersions and Gels
Sammanfattning : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The first project concern the gelation of water glass, also known as alkaline sodium silicate solutions.

5. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces
Sammanfattning : Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. LÄS MER
