1. Local Structure of Hydrogen-Bonded Liquids
Sammanfattning : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. LÄS MER
2. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water
Sammanfattning : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. LÄS MER
3. Le Fantôme de l’Opéra - Studies on Atoms and Electrons Beneath
Sammanfattning : The carbon dioxide reduction reaction is a promising candidate to tackle ecological challenges of our age. This is due to its capability of reducing carbon dioxide emission generated from the combustion of fossil fuels by converting carbon dioxide into valuable hydrocarbons. LÄS MER
4. Molecular structure and dynamics of liquid water : Simulations complementing experiments
Sammanfattning : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.

5. X-ray scattering and spectroscopy of supercooled water and ice
Sammanfattning : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. LÄS MER
