1. Development of 18F- and 68Ga-Labelled Tracers : Design Perspectives and the Search for Faster Synthesis
Abstract : This thesis deals with the design of 18F- and 68Ga-labelled positron emission tomography (PET) tracers and the development of technologies that enable faster and simpler preparation with high specific radioactivity. Techniques like microwave heating and reducing the concentrations of the precursor were investigated with this perspective. READ MORE

2. Molecular recognition and dynamics in proteins studied by NMR
Abstract : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).

3. On Biogenic Halocarbons in Antarctic Waters
Abstract : Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In the atmosphere, halocarbons are degraded by photolysis, and form reactive halogen radicals. READ MORE

4. Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions
Abstract : It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, these compounds are converted to reactive inorganic halogen compounds, which degrade ozone. READ MORE

5. Radiohalogenated Compounds for Tumor Targeting : Synthesis and Radiolabeling
Abstract : This thesis describes the synthesis and radiohalogenation of compounds of potential use for tumor targeting. The first section describes the synthesis and radioiodination of DNA intercalating compounds. The compounds are derivatives of 9-aminoacridine, and the anthracyclins daunorubicin and doxorubicin.
