1. Polar molecules in crystalline and surface environments : From first principles
Sammanfattning : With the knowledge of the composition and structure of a chemical system, be it a molecule, a two-dimensional surface or a three-dimensional crystal, it is now possible to predict the specific properties of the compound under consideration via computational studies. Molecular and periodic Hartree-Fock and DFT calculations have been used as a tool to study polar molecules and how their properties respond to the molecular environment in a crystal or on an ionic surface.

2. Insights in Li-ion Battery Interfaces through Photoelectron Spectroscopy Depth Profiling
Sammanfattning : Compounds forming alloys with lithium, such as silicon or tin, are promising negative electrode materials for the next generation of Li-ion batteries due to their higher theoretical capacity compared to the current commercial electrode materials.An important issue is to better understand the phenomena occurring at the electrode/electrolyte interfaces of these new materials.
