How does an umbrella repel raindrops? Why do your contact lenses stick to your eye? These questions can be answered when looking closely at their interfaces.
So what exactly is an interface and how do we characterize it?
An interface is defined as the boundary between two substances that are in contact without mixing. It is safe to say that these interfaces offer many interesting functionalities like how the surface of an umbrella reflects raindrops. If we can characterize different kinds of interfaces quantitatively, it’s possible that we can engineer interfaces with functionalities we want. This opens up new possibilities in engineering.
So how do we quantitatively explore interfaces?
We use Interface physics, a branch in physics intended to understand the intricate behavior of interfaces.
Here, we will explain the principles of interface physics and their applications on cutting-edge research with emphasis on the interface between water and various solids.
