1. Self aggregation of fluorocarbon surfactants and fluorocarbon- hydrocarbon surfactant mixtures
Sammanfattning : The aggregation and phase behavior of fluorocarbon surfactants in micellar, and liquid crystalline phases, and micellization in nonideal mixed fluorocarbon-hydrocarbon surfactant system have been investigated by means of a variety of techniques.The demixing in mixed surfactant systems was studied in the dilute solution region by using time-resolved fluorescence quenching measurements.

2. Bilayers with Surfactant-induced Pores and Demixing in Micelles : Studies of Segregation in Amphiphile Systems
Sammanfattning : The focus of this thesis has been on the effects of segregation in mixtures of amphiphilic molecules. Two different systems were investigated: fluorocarbon-hydrocarbon surfactant mixtures and lipid-surfactant mixtures. LÄS MER
3. Vibrational Sum Frequency Spectroscopy Studies at the Air-Liquid Interface
Sammanfattning : In this thesis the structure and hydration of small organic and amphipilic compounds adsorbed at the air-liquid interface, have been studied using the nonlinear optical technique Vibrational Sum Frequency Spectroscopy (VSFS). The second order nature of the sum frequency process makes this technique particularly surface sensitive and very suitable for interfacial studies, as molecules at the surface can be distinguished even in the presence of a vast excess of the same molecules in the bulk.
