Front propagation is studied in several reaction–diffusion models based on the Oregonator model of the Belousov–Zhabotinsky reaction. Each system involves autocatalysis (X→2X), termination (2X→0) and consumption of the autocatalyst (X→0, X1Y→0), augmented with interconversion (X↔R) between the autocatalyst X and a rapidly diffusing unreactive species R. We investigate the dependence of the fron...

Stationary and oscillatory localized patterns (oscillons) are found in the Belousov-Zhabotinsky reaction dispersed in Aerosol OT water-in-oil microemulsion. The experimental findings are analyzed in terms of subcritical Hopf instability, subcritical Turing instability, and their combination.
