Prof ZHU Pingan and his collaborators published a paper entitled Suppression of hollow droplet rebound on super-repellent surfaces in Nature Communications. The study proposes a method to prevent droplet rebound on super-repellent surfaces by introducing bubbles into the droplets. The bubbles counteract the capillary effects, reducing the momentum required for take-off. This double-spring system explains droplet behaviour, with single-phase droplets being a special case within this framework.
