Microscopic active droplets are able to swim autonomously in viscous flows. This puzzling
feature stems from solute exchanges with the surrounding fluid via surface reactions or their …

Active systems are driven out of equilibrium by exchanging energy and momentum with their
environment. This endows them with anomalous mechanical properties that are reviewed in …

Self-propelled droplets are a class of active matter systems composed of one fluid dispersed
in another immiscible fluid. Despite the inherent spherical symmetry in the initial droplet …

The field of active matter, and particularly active emulsions, is growing rapidly, with
significant progress made recently on both theoretical and experimental fronts. Here, we …

A common feature of biological self-organization is how active agents communicate with
each other or their environment via chemical signaling. Such communications, mediated by …

Artificial model swimmers offer a platform to explore the physical principles enabling
biological complexity, for example, multigait motility: a strategy employed by many …

In this Letter, a water-in-oil swimming droplet's transition from straight to curvilinear motion is
investigated experimentally and theoretically. An analysis of the experimental results and …

Solubilizing, self-propelling droplets have emerged as a rich chemical platform for the
exploration of active matter, but isotropic droplets rely on spontaneous symmetry breaking to …

Micellar solubilization is a transport process occurring in surfactant‐stabilized emulsions that
can lead to Marangoni flow and droplet motility. Active droplets exhibit self‐propulsion and …

Interfacial chemical dynamics on a droplet generate various self-propelled motions. For
example, ballistic and random motions arise depending on the physicochemical conditions …
