1. Fatty Acid Self-Assembly at the Air–Water Interface : Curvature, Patterning, and Biomimetics: A Study by Neutron Reflectometry and Atomic Force Microscopy
Sammanfattning : For more than a hundred years of interfacial science, long chain fatty acids have been the primary system for the study of floating monolayers at the air–water interface due to their amphiphilic nature and system simplicity: an insoluble hydrocarbon chain and a soluble carboxyl group at a flat air–water interface. Despite―or perhaps rather due to―the assumed simplicity of such systems and the maturity of the research field, the seemingly fundamentally rooted notion of a two-dimensional water surface has yet to be challenged.

2. Molecular Insight into Ion-Specific Interactions : Vibrational Sum Frequency Study of the Carboxylic Acid Moiety
Sammanfattning : Ion specific effects at charged interfaces find numerous applications in colloidal sciences and play a vital role in many biological processes. Despite having been studied for over a century, starting with the work of F. Hofmeister in the 1880s, a comprehensive molecular understanding remains elusive. LÄS MER
3. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains
Sammanfattning : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. LÄS MER
4. A Spectroscopic Study of Interfacial Films: Internal Structuring, Stability, and Hydration
Sammanfattning : Monolayers of molecules are capable of completely changing the nature of surfaces and their interactions with the surroundings despite their almost negligible thickness. In the research presented in this doctoral thesis the surface specific technique Vibrational Sum Frequency Spectroscopy (VSFS) was combined with the Langmuir trough to investigate various manifestations of monolayers, such as biomimetic membranes, mono methyl branched long chain fatty acids in contact with air, and hydrophobic silane monolayers in contact with water.
