1. Dynamic Wetting of Solid Surfaces, Influence of Surface Structures and Surface Active Polymers
Sammanfattning : The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). LÄS MER
2. 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
3. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays
Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.

4. Rapid wetting - influence of surface geometry and fluid properties
Sammanfattning : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. LÄS MER
5. Charge Development at Iron Oxyhydroxide Surfaces : The Interplay between Surface Structure, Particle Morphology and Counterion Identity
Sammanfattning : Iron (oxyhydr)oxide (FeOOH) minerals play important roles in various natural, technological and societal settings. The widespread abundance of these minerals has prompted numerous studies on their surface reactivity in aqueous media. Surface charge development, one that namely takes place through the adsorption of potential determining ions (p.d. LÄS MER
