Abstract

Inside Back Cover: The cover image is based on the Research Article Bubble-induced symmetry breaking in droplet impact by Zhou et al.

Cover description: On flat surfaces, impacting droplets typically exhibit symmetric bouncing dynamics. Here, we demonstrate that embedding a pair of bubbles within a droplet enables asymmetric impact behavior on super-repellent surfaces, where spreading and receding occur simultaneously. This symmetry-breaking dynamics reduces both contact time and contact area, arising from anisotropic capillary effects induced by the encapsulated bubbles. (DOI: 10.1002/dro2.70006)
