Fabrication of quasi-two-dimensional, heterogeneously curved Belousov–Zhabotinsky systems

For many years the Belousov–Zhabotinsky reaction has been used to explore the large variety of dynamical behavior of excitation waves. The understanding of chemical waves can be applied to other physical and biological systems. Most theoretical and experimental work has been done in planar media, whereas for nonplanar systems there exist many theoretical but only very few experimental studies. In this article we present a methodology to develop quasi-two-dimensional, nonhomogeneously curved reaction media. These systems can be used to perform experiments on chemical reaction-diffusion processes which occur, for instance, in the Belousov–Zhabotinsky reaction placed in nonplanar geometries. © 2003 American Institute of Physics. @DOI: 10.1063/1.1623623#
