1. Quantum photoelectrochemistry : Theoretical studies of organic adsorbates on metal oxides surfaces
Sammanfattning : 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. LÄS MER
2. Synthesis and Self-Assembly of Functional Molecules: Systems Toward Molecular Electronics
Sammanfattning : Synthesis and Self-Assembly of Functional Molecules:Systems Toward Molecular Electronics Daniel NilssonOrganic Chemistry, Department of Chemical and Biological EngineeringChalmers University of TechnologyAbstractIn this Thesis, different molecules with possible use in molecular electronics are reported. The focus is on the synthesis of the molecules and their use as adsorbates in self-assembled monolayers (SAMs). LÄS MER
3. Metal-Organic Complexes at Surfaces
Sammanfattning : The adsorption of different metal-organic complexes at surfaces was investigated by spectroscopic techniques (x-ray photoemission spectroscopy, x-ray absorption spectroscopy, resonant photoemission spectroscopy) and by scanning tunnelling microscopy. The investigation methods are able to provide atomic scale information on the studied systems, which moreover originates from the top-most atomic layers in a sample, meaning that they are surface sensitive techniques.

4. Partial methane oxidation from electronic structure calculations
Sammanfattning : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.
