Abstract
There are many parallels between the study of temporal oscillation in homogeneous chemical systems and of Turing patterns in reaction-diffusion systems. We discuss recent progress toward constructing a system that displays Turing structures under conditions suitable for a lecture demonstration. Such a system would play a role similar to that of the Belousov-Zhabotinsky oscillating reaction. We examine the prototype chlorite-iodide-malonic acid and related reactions, mathematical models, methods for designing new reactions that exhibit Turing structures and an approach to generating Turing structures in a closed system.
