Boundaries can steer active janus spheres
WebMar 18, 2024 · These spheres can be bubbles, solid particles or droplets resulting in different boundary conditions (stick or slip) on the surface of the sphere. In recent years, Janus spheres having slip and stick boundary conditions on parts of the sphere have gained importance because of their potential applications. WebThis is achieved through active quenching of their Brownian rotation by constraining it in a rotational well, caused not by equilibrium, but by hydrodynamic effects. We demonstrate …

Our system consists of Janus24 particles composed of platinum (Pt)-capped polystyrene (PS) colloids, which swim in solutions of hydrogen peroxide (H2O2) due to its catalytic decomposition into water and oxygen14. These Janus particles swim with the PS side forward, according to a self-electrophoretic … See more To further probe the role of geometry on the orientational quenching, we examine swimming of Janus particles near two orthogonal surfaces (Fig. 2a). We observe that a particle initially … See more If the surface potentials of the particles were to change significantly in the presence of the reaction, electrostatic colloidal forces could contribute to the rotational quenching. … See more Having determined the phenomenology of rotational quenching experimentally, we now set out to investigate this effect theoretically, and explore possible mechanisms that can account for these observations. The … See more Driven motion of a sphere through viscous fluid near a solid substrate that imposes no-slip boundary condition introduces coupling between translation and rotation. We can get an intuitive idea of why this coupling comes … See more
