1. Generic Properties of Polymer Solutions
Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE

2. DNA Electrophoresis in Polymer Solutions. Separation Mechanisms studied by Fluorescence and Linear Dichroism Spectroscopy
Abstract : Capillary electrophoresis of DNA in polymer solutions is a promising technique for separation of DNA molecules according to size. The primary aim of the work presented in this thesis was to get a better understanding of the electrophoretic separation mechanism in these media by studying the DNA migration behavior during electrophoresis in both entangled and non-entangled polymer solutions using linear dichroism spectroscopy and fluorescence video microscopy.

4. Polymer-Mediated Interactions and Phase Behaviour of Polymer-Particle Dispersions
Abstract : Interactions between colloidal particles can be modelled by particles grafted with polymers. In this work, structural and physical properties of colloids are investigated under variation of parameters such as pH, ionic strength, and temperature, where aggregation and cluster formation can be monitored in aqueous solution.

5. NMR Diffusion Studies in Heterogeneous Systems. Surfactant solutions, Polymer solutions and Gels
Abstract : The aim of this study has been to investigate the self-diffusion behaviour in polymer solutions and in surfactant solutions using the pulsed field gradient (PFG) NMR technique. The NMR self-diffusion experiment was shown to provide detailed information in complex surfactant mixtures. READ MORE
