1. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State
Abstract : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. READ MORE

2. Development and Evaluation of Tools to Explore Posttranslational HexNAc-Tyrosine and Mucin-Type O-Glycosylation
Abstract : Glycosylation is the most abundant form of post-translational modification (PTM). Recently, O-glycosylation attracted much attention in the glycoproteomic field due to its association with various diseases, such as pathogenic infections and cancer. READ MORE

3. Development and characterisation of protecting groups that enhance the solubility of synthetic peptides : Methods to improve the aqueous solubility of hydrophobic peptides
Abstract : Chemical synthesis of peptides is generally performed by solid phase peptide synthesis (SPPS). Although SPPS is a rapid and convenient method to prepare peptides, the major methodological problem in SPPS is related to solvation/solubility. READ MORE

4. Mechanistic Studies on Proton-Coupled Electron Transfer from Tyrosine and Tryptophan Derivatives
Abstract : Proton-coupled electron transfer (PCET) from tyrosine (Y) and tryptophan (W) is vital to many redox reactions in Nature where PCET between several Ys, or Ws, or between a mix of Ys and Ws can be used to transfer electrons, or protons, or both over large distances of several Å. Studying the PCET reaction mechanisms of Y and W is important for fundamental knowledge, and can help researchers that wish to mimic redox reactions in Nature. READ MORE

5. 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.
