16. Amylopectin - Interactions with Lipids and Proteins
Sammanfattning : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.

17. Chemically Modified Metal Oxide Nanostructures Electrodes for Sensing and Energy Conversion
Sammanfattning : The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules.

18. 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
19. Organic reactions in self-organized surfactant systems
Sammanfattning : The aim of this work has been to investigate how microemulsions and micellar systems can be used as reaction media to overcome reactant incompatibility, enhance reaction rates and especially to control product composition, i.e., introducing regioselectivity, in organic synthesis.

20. DNA Compaction at Surfaces
Sammanfattning : The interfacial behavior of DNA and DNA-cationic surfactant has been studied. Particular attention was paid to the type of cationic surfactant and the DNA conformation (single or double stranded) as well as the DNA length. LÄS MER
