Stirring active particles to form life crystal using convective flow

A convective flow concentrating active particles in a region bounded by complex surfaces can be used as a dynamic confinement to form aggregates. To achieve this, a special geometry inspired by thin film experiments was modeled. There is a discussion of the effect of motility and chirality of active particles in the formation of crystalline like structures. (C) 2018 Elsevier B.V. All rights reserved.
