Droplets and bubbles, such as rain drops in rainy season and gas bubbles in carbonated drinks, are ubiquitous in nature and daily life. Nanotechnology called droplet based microfluidics becomes one of the rapidly growing interdisciplinary fields of engineering and technology. The formation of droplets and bubbles is called heterogeneous nucleation, as it is assisted by the surface of foreign substrates. Therefore, the heterogeneous nucleation is closely related to the wetting phenomena of surface. The nucleation and wetting phenomena are areas where chemistry, physics, and engineering intersect. In my talk, first, I will give a rough idea of heterogeneous nucleation and wetting transition. Next, several topics from some of my original works in this field will be presented. Finally, I will indicate the future direction toward the microscopic understanding of these phenomena from atomic and molecular view.
