Global coupling induced 2-phase clusters during the H₂ electrooxidation at Pt in the presence of poisons

Time series	Analytical signal video
Type I 2-phase clusters
Type II 2-phase clusters

Upper plates: Time series of the global coupling; Lower plates: Spatiotemporal evolution of the double layer potential;
The videos (click on the images to the right) show the evolution of the analytical signal (obtained from a Hilbert transformation) at the center of each domain.
