1. NMR Studies of Inclusion Compounds
Sammanfattning : This thesis presents the application of some of the NMR methods in studying host-guest complexes, mainly in solution. The general focus of the work is on investigating the reorientational dynamics of some small molecules that are bound inside cavities of larger moieties. LÄS MER
2. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels
Sammanfattning : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. LÄS MER
3. Exploring the Molecular Behavior of Carbohydrates by NMR Spectroscopy : Shapes, motions and interactions
Sammanfattning : Carbohydrates are essential biomolecules that decorate cell membranes and proteins in organisms. They are important both as structural elements and as identification markers. Many biological and pathogenic processes rely on the identification of carbohydrates by proteins, thereby making them attractive as molecular blueprints for drugs. LÄS MER
4. NMR Diffusion Studies in Heterogeneous Systems. Surfactant solutions, Polymer solutions and Gels
Sammanfattning : 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. LÄS MER
5. Methods for the Synthesis of PET Tracers and NMR Studies of Ribonuclease A
Sammanfattning : This thesis contains two parts.In the first part, general and versatile palladium-mediated 11C-C bond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. LÄS MER
