Symmetrical Catalytic Colloids Display Janus‐Like Active Brownian Particle Motion
Advanced Science, 2023 Catalytic Janus colloids, with one hemi‐sphere covered by a hydrogen peroxide reduction catalyst such as platinum, represent one of the most experimentally explored examples of self‐motile active colloid systems. This paper comparatively investigates the

Review: Interactions of Active Colloids with Passive Tracers
Condensed Matter, 2019 Collective phenomena existing universally in both biological systems and artificial active matter are increasingly attracting interest. The interactions can be grouped into active-active and active-passive ones, where the reports on the purely active ...

Spatio-temporal control of the phase separation of chemically active immotile colloids
National Science Open, 2023 Understanding and controlling phase separation in nonequilibrium colloidal systems are of both fundamental and applied importance. In this article, we investigate the spatiotemporal control of phase separation in chemically active immotile colloids.

Colloids in two-dimensional active nematics: conformal cogs and controllable spontaneous rotation
New Journal of Physics, 2023 A major challenge in the study of active systems is to harness their non-equilibrium dynamics into useful work. We address this by showing how to design colloids with controllable spontaneous propulsion or rotation when immersed in active nematics.
