Liquid Droplet Bouncing on a Nanotextured Surface

Caption

A liquid droplet bouncing on a nanotextured surface powered by the Leidenfrost levitation and the Cassie state: The kinetic energy is transferred into the surface energy with small energy dissipation by the Cassie surface, which facilitates the droplet's rebound repeatedly until the capillary pressure outweighs the vapor pressure.
