6. Mechanisms of charge transfer in dissipative shuttle nanostructures
Sammanfattning : .... LÄS MER
7. Choreography of a proton pump : Studies of charge-transfer reactions in cytochrome c oxidase
Sammanfattning : In the last step of cellular respiration, electrons from metabolites are transferred to molecular oxygen, mediated by the enzyme complexes of the respiratory chain. Some of these enzyme complexes couple these redox reactions to formation of an electrochemical proton gradient across the cell membrane. The proton gradient is used e.g. LÄS MER
8. Molecular Interaction of Thin Film Photosensitive Organic Dyes on TiO2 Surfaces
Sammanfattning : The photosensitive molecule adsorption on titanium dioxide (TiO2) forms the so-called “dye sensitized TiO2” system, a typical organic/oxide heterojunction, which is of great interest in catalysis and energy applications, e.g. dye-sensitized solar cell (DSSC). Traditionally, the transition metal complex dyes are the focus of the study. LÄS MER
9. Charge-transfer excitations and phtophysical properties of molecular building blocks
Sammanfattning : This thesis reports a state-of-the-art theoretical study of photophysical properties of organic charge-transfer aromatic molecules. These molecules are building blocks of molecular functional materials used in modern photonics technology and play essential roles in chemistry and biology in general. LÄS MER
10. Experimental studies of proton translocation reactions in biological systems : Electrogenic events in heme-copper oxidases
Sammanfattning : Terminal heme-copper oxidases (HCuOs) are transmembrane proteins that catalyze the final step in the respiratory chain - the reduction of O2 to H2O, coupled to energy conservation by generation of an electrochemical proton gradient. The most extensively investigated of the HCuOs are the aa3-type oxidases, to which cytochrome c oxidase (CytcO) belongs, which uses energy released in the O2-reduction for proton pumping. LÄS MER
