16. Visualising Functional Nanostructures of Organic Semiconductors using Electron Microscopy
Sammanfattning : Organic semiconducting materials have enabled the solution-processable fabrication of light-weight and flexible electronic devices. In particular, doping using molecular dopants has enabled the fabrication of high-performance organic electronics. LÄS MER
17. Correlating Nanostructure and Electronic Properties of Organic Semiconductors by Electron Microscopy
Sammanfattning : Organic semiconductors enable fabrication and efficient processing of electronic devices with light weight, mechanical flexibility and tuneable properties. Despite significant progress in the last decades, efficiencies and long-term stabilities of these systems still need to be improved. LÄS MER
18. Porous Cellulose Materials from Nano Fibrillated Cellulose
Sammanfattning : In the first part of this work a novel type of low-density, sponge-like material for the separation of mixtures of oil and water has been prepared by vapour deposition of hydrophobic silanes on ultra-porous nanocellulose aerogels. To achieve this, a highly porous (> 99 %) nanocellulose aerogel with high structural flexibility and robustness is first formed by freeze-drying an aqueous dispersion of the nanocellulose. LÄS MER
19. Polymer Gels: Modeling the Swelling Behavior
Sammanfattning : This thesis is concerned with the swelling behavior of polyelectrolyte gels. The thesis can be divided into two parts. Part one deals with the modeling and computer simulation of the gel swelling. LÄS MER
20. Exploring the Wood Adhesive Performance of Wheat Gluten
Sammanfattning : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.
