Reactor. (a) and (c) are two thermostated chambers with sealed glass windows; arrows indicate direction of water flux from and to thermostated bath. (b) Teflon spacer between the chambers. The three parts of the reactor are pressed together and the reactive ME (red) is sandwiched between the two glass windows.

Transformations of wave patterns in bathoferroin-catalyzed BZ-AOT system: CWs, continuous trigger waves; SWs, segmented waves; JWs, jumping waves; BWs, bubble waves; and RWs, rotating waves. JW, BW, and RW are discontinuously propagating waves, while SW propagate smoothly.
Four consecutive snapshots of Turing patterns (narrow black stripes) moving nontranslationally at constant velocity of the up-moving mask (the mask is not shown). The width of the mask is slightly larger than the width of a single black stripe. Time between snapshots is 1. Horizontal size of snapshots is 30. Turing instability occurs only in the shadow of the mask.
