1. 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.

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. Hydrolytic Synthesis and Physicochemical Properties of TiO2 Nanoparticles: Fundamentals and Applications
Sammanfattning : Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with well-defined size distributions were obtained. LÄS MER
4. Effect of surface characteristics on cellular adherence and activity
Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER
5. 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
