Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability

open access: yesAdvanced Science, EarlyView.
A novel dancing electrospray phenomenon is reported characterized by high‐frequency, robust, and multi‐directional alternating ejection modes. This phenomenon arises from the electrohydrodynamic (EHD) tip streaming at the crests of Faraday waves excited on the liquid meniscus, and it offers significant advantages in high‐throughput and multi‐path ...
