Effects of tunable hydrophobicity on the collective hydrodynamics of Janus particles under flows

Understanding active colloidal systems with nonequilibrium self-organization is a long-standing, challenging area in material sciences and biology. In this work we use a colloidal suspension of Janus particles to investigate the hydrodynamics that underlies their various morphologies (unilamellar, multilamellar, and striated structures) and rheological properties.
