Graphical Abstract
Fascillating: Inhibitory coupling by bromine among nanoliter aqueous droplets containing the Belousov–Zhabotinsky (BZ) reaction solution produces anti-phase oscillations and stationary Turing patterns (see picture; reduced catalyst in red, oxidized catalyst in blue). By choosing the fundamental oscillator and the scavenger added to the connecting medium, it should be possible to construct systems with controllable degrees of inhibitory or excitatory coupling.
