Coupled oscillations in a 1D emulsion of Belousov–Zhabotinsky droplets. This article by Jorge Delgado, Ning Li, Marcin Leda, Hector O. González-Ochoa, Seth Fraden and Irving R. Epstein reports the use of a programmable illumination source to control the boundary and initial conditions of arrays of small numbers of non-linear, oscillating, micron-sized Belousov–Zhabotinsky droplets. The team say that in these small collections of droplets, transient patterns decay rapidly and they observe several more complex attractors, including ones in which some adjacent droplets are in-phase.
