1. Diastereomeric Effects in DNA Binding – Biological and Biophysical Studies on Ruthenium Complexes
Sammanfattning : Organic molecules, such as glucose and amino acids, are most often chiral. This means that their mirror-images are different, in the same way a left and a right hand are different from each other. For example, the DNA double helix in its standard form twists like a right-handed screw. LÄS MER
2. Role of charge and spin fluctuations and their interplay in solids : A Green’s function approach
Sammanfattning : Due to the large number of electrons, solid state physics boils down to many-body approximations in which only selected types of collective excitations are taken into account, guided by the emergent properties of the material under study. In this thesis, the collective excitations of primary interest are electronic charge and spin fluctuations(plasmons and magnons) and nuclear charge fluctuations (phonons). LÄS MER
3. Visualizing Interacting Biomolecules In Situ
Sammanfattning : Intra- and intercellular information is communicated by posttranslational modifications (PTMs) and protein-protein interactions, transducing information over cell membranes and to the nucleus. A cells capability to respond to stimuli by several highly complex and dynamic signaling networks provides the basis for rapid responses and is fundamental for the cellular collaborations required in a multicellular organism.

4. Thermodynamic Studies of Macromolecular Models
Sammanfattning : The thermodynamic properties of single chain polyelectrolyte and protein models are studied using Monte Carlo simulations and (for the polyelectrolyte models) variational calculations and high- and low-temperature expansions. A variational method is used for minimizing Lennard-Jones energies and for estimating end-to-end distances for a rigid Coulomb chain at finite temperatures. LÄS MER
5. Resonant Inelastic X-ray Scattering Studies on Quasi-Two-Dimensional Superconducting Materials
Sammanfattning : Unconventional superconductivity is one of the many fascinating research areas of condensed matter physics. Understanding the superconducting pairing mechanism and its connection with other competing states remains unclear. LÄS MER
