A Superhydrophobic Surface
Abstract:
A superhydrophobic surface, devised by scientists at UCLA, greatly reduces the friction felt by a fluid as it moves across the surface. It does this by inducing a blanket of air to lodge between nano-posts built onto the surface; the air keeps the fluid from coming into contact with the solid surface. Submarines and torpedoes coated with the slippery nanoengineered material would glide through the sea under much less propulsion.
