1. Spectroelectrochemistry of Redox Enzymes
Sammanfattning : A low volume and long optical path spectroelectrochemical cell was constructed and tested in a number of applications such as detection of direct electron transfer (DET) between redox enzymes and gold electrodes, determination of the formal potentials of redox centres in proteins and enzymes, as well as mechanistic studies of heterogeneous and intermolecular electron transfer of copper oxidases and succinate:quinine oxidoreductase (Complex II). The existence of DET between enzymes and electrodes was demonstrated for theophylline oxidase, cytochrome P450 cam, laccase, bilirubin oxidase, sulphite oxidase and Complex II. LÄS MER
2. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity
Sammanfattning : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.

3. Structural and biochemical analysis of two copper proteins - plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3
Sammanfattning : Plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3 are two copper-containing proteins that are involved in biological electron transport chains: plastocyanin operates in photosynthesis and nitrite reductase takes part in the denitrification pathway.

4. Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems
Sammanfattning : In this thesis electron transfer reactions and diffusion of redox molecules in three different types of self-aggregated structures are investigated. Electrochemistry was used to investigate the redox potential and diffusion coefficients for redox active molecules with different polarity. The first aggregate system studied was the micellar phase.

5. Electrochemical characterizations of conducting redox polymers with proton traps : Enabling proton cycling in aprotic systems for high potential energy storage
Sammanfattning : Floods, droughts and unpredictable weather could be the new reality for millions of people in a near future, unless we drastically decrease our greenhouse gas emissions to prevent the global average temperature from increasing even further. Material innovations will most certainly be essential for many of the technical solutions needed in order to tackle environmental issues. LÄS MER
