1. Surface Force and Friction : effects of adsorbed layers and surface topography
Sammanfattning : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. LÄS MER
2. Controlling DNA compaction and the interaction with model biomembranes
Sammanfattning : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. LÄS MER
3. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles
Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER
4. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices
Sammanfattning : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. LÄS MER
5. 11B4C containing Ni/Ti neutron multilayer mirrors
Sammanfattning : The work in this thesis covers the design, growth and characterisation of neutron multilayers. The performance of these multilayers is highly dependent on the obtained interface width between the layers, even a modest improvement can offer a substantial increase in reflectivity performance.
