Periodic waves were studied via the process of wet stamping, in a heterogeneous media soaked in different solutions of the Belousov-Zhabotinsky (BZ) reaction system containing ferroin and malonic acid. The experiments were performed by making an initial contact of soaked polyacrylamide (PAA) gel with agarose stamp for a short period of time, and then placing the gel onto the glass plate after exposing both of its surfaces. This led to the development of propagating waves on the surface of the gel. The results show that patterns have a dependence on the concentration of individual species, which are represented in the form of bifurcation diagrams. The behavioral trend of this system is also compared with the current perspectives of the reaction diffusion system. (C) 2007 Elsevier B.V. All rights reserved.
