1. Computational chemistry studies of UV induced processes in human skin
Sammanfattning : This thesis presents and uses the techniques of computational chemistry to explore two different processes induced in human skin by ultraviolet light. The first is the transformation of urocanic acid into a immunosuppressing agent, and the other is the enzymatic action of the 8-oxoguanine glycosylase enzyme. LÄS MER
2. Interfaces in Dye-Sensitized Oxide / Hole-Conductor Heterojunctions for Solar Cell Applications
Sammanfattning : Nanoporous dye-sensitized solar cells (DSSC) are promising devices for solar to electric energy conversion. In this thesis photoelectron spectroscopy (PES), x-ray absorption spectroscopy (XAS) and photovoltaic measurements are used for studies of the key interfaces in the DSSC. LÄS MER
3. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis
Sammanfattning : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. LÄS MER
