Abstract
A new photolithographic method was developed to enable precise patterning of a catalyst on a cation-exchange membrane. A large number of catalyst (ferroin) dots were arranged on triangular and square lattices to study pattern formation on a two-dimensional array of Belousov-Zhabotinsky (BZ) oscillators. When the distances among the dots were adjusted properly, the propagation of anisotropic chemical waves was experimentally observed in the discrete BZ reaction systems.Keywords
