6. Regulation of Proton Coupled Electron Transfer from Amino Acids in Artificial Model Systems: A Mechanistic Study
Abstract : Amino acid radicals are key redox intermediates in several natural enzymes including Cytochrome c peroxidase, DNA photolyase, ribonucletide reductase, cytochrome c oxidase and photosystem II. Electron transfer from amino acids is often coupled to deprotonation and this thesis concerns the coupling of electron transfer from tyrosine and tryptophan to trisbipyridineruthenium(III) with deprotonation in model complexes.

7. Electron Transfer in Ruthenium-Manganese Complexes for Artificial Photosynthesis : Studies in Solution and on Electrode Surfaces
Abstract : In today’s society there is an increasing need for energy, an increase which for the most part is supplied by the use of fossil fuels. Fossil fuel resources are limited and their use has harmful effects on the environment, therefore the development of technologies that produce clean energy sources is very appealing. READ MORE

9. Proton, Electron, and O2 transfer in Cytochrome c Oxidase
Abstract : In mitochondria and aerobic bacteria energy conservation involves electron transfer through the membrane-bound protein of the respiratory chain to oxygen. Cytochrome c oxidase (CcO) catalyzes the reduction of oxygen to water. Part of the energy released in this reaction is used to pump protons across the membrane. READ MORE

10. Synthesis and Photoinduced Electron Transfer of Donor-Sensitizer-Acceptor Systems
Abstract : Artificial systems involving water oxidation and solar cells are promising ways for the conversion of solar energy into fuels and electricity. These systems usually consist of a photosensitizer, an electron donor and / or an electron acceptor. READ MORE
