1. Quantum photoelectrochemistry : Theoretical studies of organic adsorbates on metal oxides surfaces
Abstract : Interactions between organic molecules and transition metal oxide surfaces have been investigated by means of quantum chemical calculations. The studies have been aimed at understanding electrode-adsorbate interactions in photoelectrochemical devices, such as dye-sensitized solar cells. READ MORE

2. Development and Application of a First Principle Molecular Model for Solvent Effects
Abstract : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. READ MORE

3. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study
Abstract : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. READ MORE
