Phoretic dynamics of colloids in a phase separating critical liquid mixture
Thomas Zinn, Lewis Sharpnack, Theyencheri Narayanan
Abstract
This article presents the emergent dynamics of St\"ober and Janus colloids upon the spinodal phase separation of the suspending medium investigated by dynamic X-ray scattering. Both colloids manifest an enhanced dynamics dominated by strong velocity fluctuations and anomalous diffusion akin to superdiffusion.
