1. Electronic and Structural Properties of Thin Films of Phthalocyanines and Titanium Dioxide
Sammanfattning : This thesis is based on experimental studies in chemical physics. Titanium dioxide (TiO2) and phthalocyanine’s (Pc’s), interesting in many future perspectives, have been deposited as thin films and studied as follows. Information has been obtained on e.g. LÄS MER
2. Electrochromic Properties of Iridium Oxide Based Thin Films
Sammanfattning : Electrochromic iridium oxide (IrOx) and iridium-tantalum oxide (IrTaOx) thin films were prepared by reactive magnetron sputtering. Composition, density, and structure were determined using Rutherford backscattering spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy.

3. Protonmotive coupling of energy conversion processes in photosyntetic bacteria : studies on membrane energization and photophosphorylation capacity
Sammanfattning : This work is a study on the membrane-bound inorganic pyrophosphatase and other energylinkedenzymes in the chromatophores from the photosynthetic bacterium Rhodospirillum rubrum.The membrane-bound inorganic pyrophosphatase is functionally similar to the well-known FiF0-ATP synthase.

4. Characterization of interfaces by elastic light scattering and profilometry
Sammanfattning : This thesis deals with the characterization of interfaces by elastic light scattering and profilometry. The sensitivity of scattering measurements to surface topography were used in two major ways. It was shown that surface reactions in a liquid-solid interface can be monitored in situ in terms of changes in surface roughness. LÄS MER
5. Electrochromism in Nickel-based Oxides : Coloration Mechanisms and Optimization of Sputter-deposited Thin Films
Sammanfattning : Electrochromic properties of sputter-deposited nickel-based oxide films have been studied with a two-fold goal. From a practical point of view, the optical switching performance has been improved by optimizing the deposition conditions and film stoichiometry with respect to oxygen and hydrogen, and further by adding Mg, Al, Si, Zr, Nb or Ta to the films.
