1. 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
2. Quantum chemical characterization of oxide nanoparticles and interactions on their surfaces
Sammanfattning : Titanium dioxide and related oxide materials have been investigated using density functional theory calculations. Nanocrystalline particles were modelled by a finite cluster approach. LÄS MER
3. Computational Investigation of Dye-Sensitized Solar Cells
Sammanfattning : Interfaces between semiconductors and adsorbed molecules form a central area of research in surface science, occurring in many different contexts. One such application is the so-called Dye-Sensitized Solar Cell (DSSC) where the nanostructured dye-semiconductor interface is of special interest, as this is where the most important ultrafast electron transfer process takes place.

4. Self-Assembling Surfactant Aggregates for Synthesis of Nanomaterials
Sammanfattning : The main objective of this thesis was to study how surfactant assemblies can be used as templates to form inorganic nanomaterials. Both water-in-oil microemulsions and liquid crystalline phases have been used as structure directing agents. LÄS MER
5. Formic acid adsorption and photodecomposition on rutile TiO2 (110) : An in situ infrared reflection absorption spectroscopy study
Sammanfattning : TiO2 based photocatalysis is an emerging green nanotechnology that can be used forremoval of pollutants from water and air. It has had an increased research interest, bothfrom an application and fundamental point of view, during the last decades. LÄS MER
