6. Studies on the Non-covalent Interactions (Stereoelectronics, Stacking and Hydrogen Bonding) in the Self-assembly of DNA and RNA
Abstract : This thesis is based on ten publications (Papers I-X). The phosphodiester backbone makes DNA or RNA to behave as polyelectrolyte, the pentose sugar gives the flexibility, and the aglycones promote the self-assembly or the ligand-binding process. READ MORE

7. Hydrogen Bonded Phenols as Models for Redox-Active Tyrosines in Enzymes
Abstract : This thesis deals with the impact of hydrogen bonding on the properties of phenols. The possibility for tyrosine to form hydrogen bonds to other amino acids has been found to be important for its function as an electron transfer mediator in a number of important redox enzymes. READ MORE

8. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles
Abstract : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. READ MORE

9. Structure, Bonding and Chemistry of Water and Hydroxyl on Transition Metal Surfaces
Abstract : The structure, bonding and chemistry of water and hydroxyl on metal surfaces are presented. Synchrotron based x-ray photoelectron- and x-ray absorption spectroscopy along with density functional theory calculations mainly form the basis of the results. READ MORE

10. Symmetry in Asymmetric Catalysis and Hydrogen Bond-Based Self-Assembly : Synthesis and Investigations
Abstract : The thesis elaborates on four different projects focusing on synthesizing symmetry-related molecules and investigating their performance as catalysts for asymmetric catalysis or as monomers for hydrogen bond-based self-assembly.Chapter 2 describes a new method to desymmetrize a meso-ligand.
