We experimentally study the spatiotemporal reaction-diffusion patterns exhibited by the chlorite-tetrathionate reaction in a conical piece of gel. Since the nonequilibrium states of this reaction-diffusion system depend on the thickness of the gel, o

Experimental studies of the formation of Turing patterns in the (chlorine dioxide, iodine, malonic acid) reaction are performed in a spatial open gel disk reactor where all the input species are fed onto one side by a continuous stirred tank reactor.

In an one-side-fed open spatial reactor operated with the chlorine dioxide−iodine−malonic acid reaction in the presence of polyvinyl alcohol, we systematically studied the growth dynamics of Turing patterns after a supercritical parameter change.

Patterns resulting from the sole interplay between reaction and diffusion are probably involved in certain stages of morphogenesis in biological systems, as initially proposed by Alan Turing. Self-organization phenomena of this type can only develop

We elaborate on the transition from quasi-two-dimensional to three-dimensional Turing patterns in a chemical reaction-diffusion system confined in gradients of chemicals between two feed boundaries. This transition is observed in open spatial reactor

We describe experimental evidence of stable triangular and hexagon-band mixed mode nonstandard patterns, in a three-dimensional chemical reaction-diffusion system with steep gradients of chemical constraints. These gradients confine the structures in

We present some theoretical concepts that have been used in the study of chemical disspative structures together with a brief description of recent experimental work on Turing patterns and their interaction with travelling waves.

We give a brief review of recent observations of Turing patterns in an isothermal single-phase chemical system. The basic principles of open spatial reactors used in the experiments are described. Different types of one-, two- and three-dimensional s

We report the experimental observation of an endogeneous antisymmetric wave source in a quasi-one-dimensional chemical system. Substantiated by numerical simulations, a theoretical interpretation relying on the interaction between Turing and Hopf mod

Self-sustained trains of excitation waves have been produced in an open annular gel reactor in which the Belousov-Zhabotinsky (BZ) reaction was operated. The detailed morphology of the crescent-shaped waves which rotate around the annulus (“excyclo
