1. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces
Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

2. The effect of surface steps and oxides on the catalytic activity on model Pd and Rh catalysts
Sammanfattning : A catalyst is a substance that can speed up the rate of a chemical reaction without itself being consumed. Catalysts are crucial for chemical production industries, where about 90% of all chemicals are produced using catalysts. LÄS MER
3. Surface Force and Friction : effects of adsorbed layers and surface topography
Sammanfattning : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. LÄS MER
4. Electronic and Molecular Surface Structures of Dye-Sensitized TiO2 Interfaces
Sammanfattning : The dye-sensitized solar cell is a promising solar cell technology. In these systems the key process for light to electricity conversion is molecular in nature and is initiated in dye molecules adsorbed at a semiconducting surface. LÄS MER
5. On surface structure characterization and application on additive manufacturing
Sammanfattning : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. The fast-growing industry of additive manufacturing admits the surface roughness as one of the main challenges. LÄS MER
