    A single light-driven Janus particle confined in a very thin oil droplet at an air-water interface displays intriguing dynamics. While laser activation induces rapid horizontal motion ( 1 m m / s – 1 c m / s ) by thermal Marangoni flow, the particle exhibits unexpected periodic circular motions or intermittent irregular motions. We show that the trajectories are the result of a coupling between the self-propulsion of the particle and the spatiotemporal droplet thickness changes. We propose a simple model where the properties of the active particle trajectories are governed by capillary forces and torques due to the confinement of the particle in the thin droplet.

  • Continuous Emulsion Channels Achieved by Controlling the Aqueous–Oil Interface Solely with Rough Colloids Reviewed

    Abstract

    As a new class of soft materials, continuous emulsion channels have been successfully stabilized solely by rough colloids, which exhibit unique capability in sterically controlling liquid–liquid interfaces. Once jammed at the interface, the roughness‐enhanced frictions can slow down the dynamics of phase separation, and the interlocking behaviors would constrain their relative motions and generate force structures that provide mechanical support for the created emulsions. Ethanol is used to ensure the particles’ absorption, whose migration can modify the interfacial tension, and increase the solubility of active ingredients (e.g., curcumin). Applying rough colloids in ethanol‐containing systems opens new pathways toward the generation of novel structures and materials, where the parallel but separate functionalities provided by various phases demonstrate wide‐ranging applications, especially in delivery systems with variably soluble components.
