6. Interactions between DNA and counterions : an NMR relaxation and self-diffusion study
Sammanfattning : .... LÄS MER
7. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging
Sammanfattning : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.

8. Adsorption, aggregation and phase separation in colloidal systems
Sammanfattning : The thesis presents work regarding amphiphilic molecules associated in aqueous solution or at the liquid/solid interface. Two main topics are included: the temperature-dependent behavior of micelles and the adsorption of dispersants on carbon nanotube (CNT) surfaces. LÄS MER
9. Properties of Asphaltenes with emphasis on NMR self-diffusion as the investigating technique
Sammanfattning : Asphaltenes are high-molecular weight, highly aromatic molecules that have a strong tendency to aggregate. Asphaltenes are found in oil and may, if they form particles, cause problems during oil production and handling. LÄS MER
10. NMR Studies of Colloidal Systems in and out of Equilibrium
Sammanfattning : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. LÄS MER
