DOI: 10.1002/adfm.202506352

Abstract: Achieving 2D/3D self‐propulsion of aqueous microdroplet with light‐sensitive cargos presents a big challenge. Here, on a superhydrophobic LiNbO3:Fe surface with a high triboelectricity, a rocking‐assisted charging mode of aqueous microdroplets, is demonstrated namely charging through… read more here.
