Interface Physics 〜3.Cassie-Baxter equation〜 In “Interface Physics 〜2.Wenzel’s equation〜”, we discussed Wenzel’s equation. The equation describes the inherent “wettability” gets emphasized as the surface roughness (degree of unevenness) increases.… Interface Physics, Physics
Interface Physics 〜2.Wenzel’s equation〜 Surface roughness is important in improving surface wettability. Now let’s consider a surface that is R times rougher than the flat surface we previously considered.… Interface Physics, Physics
Interface Physics〜1.Young’s equation〜 There are four types of states of matter: solid, liquid, gas, and plasma. Among them, “liquid” state, represented by water, has an incompressible volume but no distinct shape, unlike the other three states.… Interface Physics, Physics
Introduction of interface physics 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? … Interface Physics, Physics
