1. Non-ionic block copolymers and proteins at the air-water interface
Sammanfattning : The behavior of block copolymer and protein films at interfaces is of central importance to their function in many application areas. Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers function e.g. LÄS MER
2. Ellipsometry studies of liquid interfaces: New methodology and applications
Sammanfattning : Adsorption of several surface active agents, such as nonionics, diblock copolymers, triblock copolymers, proteins and phospholipids at the oil/water and air/water has been studied. In order to be able to do this, a new ellipsometry setup, which utilizes light guides, was developed and tested. LÄS MER
3. Self Assembly at the Liquid Air Interface
Sammanfattning : The aim of this work is to study the interfacial properties of amphiphilic compounds at the liquid–air interface in an attempt to develop a comprehensive understanding of their orientation as well as the influence of their interaction with the solvent on the interfacial layer properties. Using Vibrational Sum Frequency Spectroscopy (VSFS) as the main tool, the molecular structure of the amphiphilic layer and the amphiphile–solvent relation can be illuminated in great detail – it is arguably the most sensitive surface spectroscopy currently available. LÄS MER
4. Exploring the Surface of Aqueous Solutions : X-ray photoelectron spectroscopy studies using a liquid micro-jet
Sammanfattning : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. LÄS MER
5. Reactions between alkyl xanthate monolayers and metal ions on aqueous substrates, and the water transport through amphiphilic films at the air-water interface
