Conversion Mechanism of Front-Side Marangoni Convection to Droplet Motion in Continuously Moving Self-Propelled 1‑Hexanol Droplet on an Aqueous Solution

When a 1-hexanol droplet is laid down on a hexanol aqueous solution surface, it exhibits a self-propelled motion. The Marangoni flow in front of the droplet plays an important role in the self-propulsion, but it was so far unclear how the flow is converted into the driving force. In this study, the...
