16. Bridge Mediated Electron Transfer in Conjugated and Cross-Conjugated Donor-Acceptor Compounds
Sammanfattning : Detailed understanding of electron transfer reactions is important in many aspects of chemistry, biology and solar energy conversion.The main aim of this thesis is to provide further insight into electron transfer through highly conjugated bridge structures. LÄS MER
17. Exploring Electron Transfer Dynamics of Novel Dye Sensitized Photocathodes : Towards Solar Cells and Solar Fuels
Sammanfattning : The design of dyes for NiO-based dye-sensitized solar cells (DSSCs) has drawn attention owing to their potential applications in photocatalysis and because they are indispensable for the development of tandem dye-sensitized solar cells. The understanding of the electron transfer mechanisms and dynamics is beneficial to guide further dye design and further improve the performance of photocathode in solar cells and solar fuel devices.

18. Photoinduced Electron and Energy Transfer in Π-Conjugated Systems
Sammanfattning : Photosynthesis is a fascinating process that provides food and oxygen. In this thesis, focus is on understanding and controlling the early processes of photosynthesis, namely photoinduced energy and electron transfer. LÄS MER
19. Femtosecond Dynamics and Photochemistry in Solution
Sammanfattning : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.

20. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP
Sammanfattning : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. LÄS MER
