1. Biomimetic Membranes: : Molecular Structure and Stability Studies by Vibrational Sum Frequency Spectroscopy
Sammanfattning : In the research presented in this licentiate thesis the surface specific technique Vibrational Sum Frequency Spectroscopy, VSFS, combined with the Langmuir trough has been utilized to investigate Langmuir monolayers and Langmuir-Blodgett (LB) deposited mono- and bilayers of phospholipids. Their molecular structure, stability, and hydration were probed to gain additional understanding of important properties aiming at facilitating the use of such layers as model systems for biological membranes.

2. Phospholipid membranes in biosensor applications : Stability, activity and kinetics of reconstituted proteins and glycolipids in supported membranes
Sammanfattning : In this study the formation of supported membranes onto planar solid supports has been investigated. The stability and activity of reconstituted membrane receptors has been studied. The potential use of such preparations in biosensor applications is discussed.The lipid films were made by the Langmuir Blodgett and by the liposome fusion techniques. LÄS MER
3. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces
Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

4. Nanoscale studies of the atmospheric corrosion of copper protected by ultrathin organic films
Sammanfattning : Copper (Cu) has been utilised by humans for millenniums and has become an indispensable metal in modern industry and in our infrastructure. However, corrosion, as a natural process for metallic materials, takes place on copper surfaces in most environments. LÄS MER
5. POLYPEPTIDES - STRUCTURES AND INTERACTIONS IN MONOLAYERS AND AQUEOUS SOLUTIONS
Sammanfattning : The aim of this thesis work is to understand and be able to control polypeptide conformation and interactions at interfaces and in solution by changing the solution conditions. For this purpose simple model polypeptides, so-called polyamino acids, have been investigated at the air-liquid interface, as well as in aqueous solutions. LÄS MER
