dc.description.abstract | Symmetry breaking and the emergence of self-organized patterns is the hallmark of complexity. Here, we demonstrate that a sessile drop, containing titania powder particles with
negligible self-propulsion, exhibits a transition to collective motion leading to self-organized
flow patterns. This phenomenology emerges through a novel mechanism involving the
interplay between the chemical activity of the photocatalytic particles, which induces Marangoni stresses at the liquid–liquid interface, and the geometrical confinement provided by
the drop. The response of the interface to the chemical activity of the particles is the source
of a significantly amplified hydrodynamic flow within the drop, which moves the particles.
Furthermore, in ensembles of such active drops long-ranged ordering of the flow patterns
within the drops is observed. We show that the ordering is dictated by a chemical communication between drops, i.e., an alignment of the flow patterns is induced by the gradients
of the chemicals emanating from the active particles, rather than by hydrodynamic
interactions. | es |
