1. Characterising Halogen Bonding in a Cooperative Model System
Sammanfattning : Non-covalent interactions are the main driving factor for secondary structure formation of biomacromolecules and are of enormous importance for the direction of molecular recognition events, for example those of importance for drug discovery. Profound understanding of these interactions is of vital importance to achieve high affinity and selectivity of a ligand to a chosen target. LÄS MER
2. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction
Sammanfattning : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. LÄS MER
3. Spirocyclic diacyloxyselenuranes and 2-halogen substituted selenides : a synthetic and a mechanistic approach
Sammanfattning : .... LÄS MER
4. Low smoke halogen-free materials for wire and cable applications
Sammanfattning : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. LÄS MER
5. Reactivity of late transition metal complexes towards CO2 and other electrophiles
Sammanfattning : In times when dwindling energy resources is a major long-term problem for sustaining modern infrastructure and technologies, we need to focus on more enduring solutions. A key contribution to this achievement is catalysis. LÄS MER
