Spontaneous and directional water droplet transportation based on patterned surface with super-wettability is crucial for the development of frontier science technology. However, cannot meet both long distance fast simultaneously. Here, we overcame this limitation by proposing an asymmetric serial brachistochrone-shaped pattern (ASBP). Water could be transported ASBP a 72.52 mm velocity 158 mm/s after series single-factor experiments, orthogonal design optimization, junction transition...

A spontaneous fast-moving air film not only prevents the escape of supplied bubbles but also replenishes on a superhydrophobic surface, which shows an amazing 27% drag reduction rate and simultaneous 80% antifouling rate.

The atmosphere contains ≈1.3 billion tons vapor that can be condensed to obtain water, which has the promise of alleviating water crisis. However, droplets are difficult shed from condensation surface means a low refreshing frequency, showing collection rate and efficiency. Here, this limitation is successfully overcome by proposing novel superhydrophobic absorber (SCA). All surfaces SCA but covered with series superhydrophilic through pores points enabled rapid droplet nucleation...

Superhydrophobic nickel surfaces have significant advantages in the field of corrosion protection compared with traditional methods which need a toxic chemical inhibitor. Electrochemical etching, an ideal method for fabricating superhydrophobic surfaces, was also limited by low current density, resulting processing efficiency. To overcome this limitation, we proposed new to fabricate surface using wire electrochemical etching method. The accomplished process sweeping controlled cathode...

Stereo version is a well-known technique for obtaining depth and surface information of objects from images captured by two cameras. In general, this limited camera occlusion inherent to grooved or steep profiles in 3D shape measurements. To alleviate problem, traditional dual-camera system accompanied with projector based on the stereo vision principle presented. The was considered as virtual camera. Three sets systems were then obtained each cameras at same global coordinates topography...
