1. Tuning of Energy and Electron Transfer Rates in Donor-Bridge-Acceptor Systems
Abstract : The intramolecular processes of Donor-Bridge-Acceptor (D-B-A) systems have been investigated by spectroscopic methods. The systems consist of porphyrin donors and acceptors linked by oligo-p-phenyleneethynylene bridges. READ MORE

2. Ultrafast, Non-Equilibrium Electron Transfer Reactions of Molecular Complexes in Solution
Abstract : Photoinduced electron transfer is a fundamentally interesting process; it occurs everywhere in the natural world. Studies on electron transfer shed light on questions about the interaction between molecules and how the dynamics of these can be utilized to steer the electron transfer processes to achieve a desired goal.

3. Direct electron transfer based biofuel cells : operating in vitro and in vivo
Abstract : I vår moderna värd är vi väldigt beroende av elektrisk energi som vi använder för det mesta i får vardag: för att lysa upp våra hus, generera värme, driva våra datorer och mobiltelefoner och mycket mer. Produktion av elektrisk energi har dock ofta en negativ på-verkan på vår miljö. READ MORE

4. Extracellular electron transfer features of the Gram-positive bacterium Enterococcus faecalis
Abstract : Electroactive microorganisms possess the unique ability to transfer electrons to or from a solid phase electron conductor, e.g., electrodes or minerals, through various physiological mechanisms. 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.
