Abstract Superhydrophobic surfaces, which have the excellent characteristics of self-cleaning, low-adhesion and non-wetting, been widely used in field biochemical analysis by limiting sample loss. In this paper, a method to generate droplets appropriate volume superhydrophobic holes was proposed. First, super-hydrophobic surface with fabricated laser etching low energy modification. Then, possi...

Inspired by the ability of lotus leaves to repel water, super hydrophobic coatings are engineered and used reduce drag. The prospect drag reduction depends on surface geometry flow conditions. In this work, we suggest a new mechanism incorporating resistance induced inside lubricating layer which could be responsible for decrease drag-reduction performance in laminar regime. A simple model comb...
