Physicists explain–and eliminate–unknown force dragging against water droplets on superhydrophobic surfaces
Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it’s commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics of how water droplets behave. Black silicon is a superhydrophobic material, meaning it repels water. Due to water’s … Read more
