Abstract

Front Cover: The cover image is based on the Research Article When contact lines remember: Surface charge and the evolving interaction with defects by Xiang et al. Cover description: This cover depicts a sliding droplet whose advancing contact line is pulled toward a surface defect by spontaneous electrification prior to physical contact. In this study, ultrafast, high-resolution microscopy reveals history-dependent contact-line dynamics driven by surface charges, uncovering an overlooked electrostatic mechanism in dynamic wetting. These insights pave the way for programmable wettability and advanced droplet control. (DOI: 10.1002/dro2.70039)
