摘要
The standing concentration patterns recently discovered in open gel-filled reactors, with the chlorite-iodide-malonic acid (CIMA) oscillating reaction in the presence of starch, were ascribed to a Turing-type reaction-diffusion symmetry breaking instability. Here we extend the investigations to other regions of parameters, with a particular emphasis to the role played by the chemical nature of the gel matrix and by the starch concentration on the onset of stationary patterns. Stationary Turing patterns are shown to develop in gel-free systems. Transitions between stationary Turing structures and wave patterns are presented. The first evidence of an anti-symmetric "homogeneous" wave source is presented.
