Droplet Manipulations: Nonspecular Reflection of Droplets (Small 3/2021)

Dimples can break all symmetries in the law of reflection and make the bouncing of droplets on super-repellent surfaces non-specular, reported by Liqiu Wang and co-workers (article number 2006695), and thus functioning as a “magic” hand to enable various on-demand droplet manipulations including trapping, shedding, antigravitational transporting, targeted positioning, and coalescing.
