Meandering spiral waves in a bubble-free Belousov–Zhabotinsky reaction with pyrogallol

Light-driven dynamic Archimedes spirals and periodic oscillatory patterns of topological solitons in anisotropic soft matter

“…Dynamics, pattern formation and other non-equilibrium processes in soft and biological matter attract a great deal of attention [1][2][3][4][5][6][7], especially when they are light-driven or fieldcontrolled [8][9][10][11][12][13]. Beyond their fundamental importance in modeling similar processes in biology [1,2], e.g.…”

Inhibitory effect of oxygen on excitation waves in the Belousov–Zhabotinsky reaction with different excitability

“…[24,34] in order to obtain a continuous wave train propagating toward the atmospheric interface boundary. Figure 1 illustrates a spiral wave emitting fronts continuously below the inhibited layer in an experiment of the BZ reaction composed of the standard concentrations just described.…”

“…The influence of atmospheric oxygen on propagating waves in a uniform thin layer of the BZ reaction was investigated using a flat rectangular reactor constructed from transparent plexiglas plates as in [24,34]. The volume of the medium was 100 mm × 100 mm × 1.0 mm.…”

The Crystalline Dynamics of Spiral-Shaped Curves

“…The spiral waves observed in the Belousov-Zhabotinsky reaction are most likely the best-known examples of such the presence and much attention has been focused on both numerical and analytical modeling of this phenomena. We mention in this context the articles by Belmonte et al [3], Jahnke and Winfree [12], Luengviriya et al [13], Mikhailov et al [14], and the references therein. Secondly, understanding the spiral shapes by constructing appropriate models seems interesting from the purely mathematical point of view.…”
