1. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions
Sammanfattning : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. LÄS MER
2. Reactivity of Metal Clusters with Diatomic Molecules
Sammanfattning : The reactivity of transition-metal clusters, in the approximate size range 10-60 atoms, with diatomic molecules has been investigated. A pulsed beam of neutral clusters is produced by a laser-vaporization source and passed through a low-pressure reaction cell containing the reactive gas. LÄS MER
3. Integration and topology of membrane proteins
Sammanfattning : Membrane proteins comprise around 20-30% of most proteomes. They play important roles in most biochemical pathways. All receptors and ion channels are membrane proteins, which make them attractive targets for drug design. Membrane proteins insert and fold co-translationally into the endoplasmic reticular membrane of eukaryotic cells. LÄS MER
4. The actinorhizal plant Datisca glomerata : interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms
Sammanfattning : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. LÄS MER
5. Investigation of [N-X-N]+ and [N-C-N]+ complexes in solution : Exploring Geometry, Stability and Symmetry
Sammanfattning : Halogen bonding is a weak interaction. In this thesis the three center four electron halogen bond, [N−X−N]+, has been studied. The lighter halogens form highly unstable halonium ions that are reactive towards nucleophiles and their complexes were therefore investigated at low temperatures. LÄS MER
