21. Structure of Small Icosahedral Viruses
Sammanfattning : This thesis presents structural studies on the plant virus Ryegrass mottle virus (RGMoV), the bacteriophage φCb5, and the icosahedral particles and octahedral crystal assembly of a bacteriophage MS2 coat protein mutant. In contrast to other sobemoviruses, the RGMoV coat protein is missing several residues in two of the loop regions important for capsid assembly. LÄS MER
22. Titania Nanoscale Films and Surfaces : Surface Science Investigation of Structure and Properties
Sammanfattning : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). LÄS MER
23. Combined Molecular Dynamics and Embedded-Cluster Calculations in Metal Oxide Surface Chemistry
Sammanfattning : The development and improvement of the functionality of metal oxides in heterogeneous catalysis and other surface chemical processes can greatly benefit from an atomic-level understanding of the surface chemistry. Atomistic calculations such as quantum mechanical (QM) calculations and molecular dynamics (MD) simulations can provide highly detailed information about the atomic and electronic structure, and constitute valuable complements to experimental surface science techniques.

24. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon
Sammanfattning : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. LÄS MER
25. Computational Insights on Functional Materials for Clean Energy Storage : Modeling, Structure and Thermodynamics
Sammanfattning : The exponential increase in the demands of world’s energy and the devastating effects of current fossil fuels based sources has forced us to reduce our dependence on the current sources as well as finding cleaner, cheaper and renewable alternates. Being abundant, efficient and renewable, hydrogen can be opted as the best possible replacement of the diminishing and harmful fossil fuels. LÄS MER
