We showed directional adhesion on the superhydrophobic wings of butterfly . A droplet easily rolls off surface along radial outward (RO) direction central axis body, but is pinned tightly against RO direction. Interestingly, these two distinct states can be tuned by controlling posture (downward or upward) and airflow across (along direction), respectively. Research indicated that special abilities resulted from direction-dependent arrangement nano-tips ridging nano-stripes micro-scales...

Constructing stable electrodes which function over long timescales at large current density is essential for the industrial realization and implementation of water electrolysis. However, rapid gas bubble detachment usually results in peeling-off electrocatalysts performance degradation, especially term operations. Here we construct a mechanically-stable, all-metal, highly active CuMo6S8/Cu electrode by in-situ reaction between MoS2 Cu. The Chevrel phase exhibits strong binding...

A smart role of the leaf margin makes lotus surface dry when a floats on water's surface. It is mainly attributed to anisotropic topography composed flat folds at margin, which are quite different from upper including micro-papillae. The around forms ring-band, introduces strong energy barrier against water that tends return leaf. As result, underneath hardly overflows onto by getting across margin. Thanks ultra narrowness can still be shed through This finding helps understanding structure...
