In the case of confined (small) systems interfacial energies can contribute significantly to the overall system energy and thus affect or even dominate the system behavior.
Well-known examples for these cases are nucleation and growth (phase transition) processes or the wetting/dewetting behavior of thin films. We will present and analyze experiments on the nucleation and growth of aggregates of C60 (fullerenes) on nanostructured planar substrates and on the bubble formation initiated by an individual, localized nano size active nucleation site. In the context of our nucleation/precipitation studies we will analyze shortly the physics of spin casting as one of our main experimental techniques. With macroscopic sessile droplets we will analyze how local surface tension gradients and the resulting surface (Marangoni) flows affect the evaporation of individual droplets and the drop/drop-coalescence behavior including cases with reacting liquids.
