1. Free Molecular and Metal Clusters Studied by Synchrotron Radiation Based Electron Spectroscopy
Sammanfattning : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. LÄS MER
2. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds
Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER
3. Regenerable Organochalcogen Antioxidants : An Explorative Study
Sammanfattning : Antioxidants are widely used to protect organic materials from damages caused by autoxidation, an oxidation process that occurs under normal aerobic conditions. In this thesis, novel multifunctional organoselenium and organotellurium antioxidants were designed, synthesized, and evaluated in search for compounds with better radical-trapping capacity, regenerability, and hydroperoxide-decomposing ability.

4. Ultrafast Photo-induced Reaction Dynamics of Small Molecules
Sammanfattning : The main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom.

5. Measurement of primary DNA damage in individual cells from humans and mice using the alkaline single cell gel electrophoresis assay
Sammanfattning : Primary DNA damage is considered to be an important step in the development of tumours and itmay also serve as a biomarker of genotoxic stress. Measurement of DNA strand breaks in peripherallymphocytes can yield useful information about the suitability of these cells for biomonitoring purposesand subsequently risk assessment. LÄS MER
