The Reversal and Splitting of Waves in an Excitable Medium Caused by an Electrical Field
TL;DR: The reversal and splitting of traveling concentration waves was observed in a one-dimensional Belousov-Zhabotinski reaction medium under the influence of low-intensity electric field gradients and the secondary role of generated hydrodynamic flow on wave transformation was investigated.
Journal ArticleDOI
Electric field induced lateral instability in a simple autocatalytic front
TL;DR: In this article, the effect of ionic drift caused by small constant electric field on autocatalytic reaction fronts of the ionic species is studied both theoretically and numerically.

Propagating fronts in 2D Cr(OH) 3 precipitate systems in gelled media
Rabih Sultan,Shoghag Panjarian +1 more
TL;DR: In this paper, the authors used a specially designed Petri dish to study the Cr(OH)3 ring propagation in the presence and the presence of a constant electric field, where the field is applied along a radial direction and the front velocities with the field on are compared with the absence and the field free case.

Concentration wave propagation in two-dimensional liquid-phase self-oscillating system.
TL;DR: This work deals with patterns in a thin layer of solution, in which cerium ions catalyse the oxidation of analogues of malonic acid by bromate by oscillations in the solution colour.
Journal ArticleDOI
Spiral Waves of Chemical Activity
TL;DR: The Zhabotinsky-Zaikin reagent propagates waves of chemical activity that include spiral waves, resembling involutes of the circle, that appear, persist, and eventually exclude all concentric ring waves.

Scroll-shaped waves of chemical activity in three dimensions.
TL;DR: This "dissipative structure" organizes reaction stages periodically in space and time everywhere except along its rotation axis, which may therefore be a thermodynamically unique locus.
Journal ArticleDOI
Ionic regulation of egg activation.
TL;DR: The ionic mechanisms which pertain in nerve and muscle have their counterparts in other cells, and just as alterations in intracellular ion concentrations serve a signalling function in excitable tissue, so too they act as signals during development.

Detailed studies of propagating fronts in the iodate oxidation of arsenous acid
TL;DR: In this paper, a single propagating wave of chemical reactivity was observed in an unstirred thin film of solution containing iodate and arsenous acid, and the wave appeared as a narrow blue band propagating through a colorless solution in reaction mixtures containing arsenous acids in stoichiometric excess.
