“…The system is now commonly known as the Belousov-Zhabotinsky (BZ) reaction (Zaikin & Zhabotinsky, 1970;Field & Burger, 1985). Since then, the study of chemical oscillations and wave formation has blossomed, which led to the observation of various nonlinear spatiotemporal behaviours such as both simple and complex oscillations in a stirred system (Smoes, 1979;Györgi & Field, 1992;Wang et al, 1995Wang et al, & 1996Zhao et al, 2005), Turing pattern (Horváth et al, 2009), target and spiral waves in a two-dimensional reactiondiffusion medium (Zaikin & Zhabotinsky, 1970;Winfree, 1972;Yamaguchi et al, 1991;Steinbock et al, 1995;Kádár et al, 1998), and scroll waves in a 3-dimensional system (Welsh et al, 1983;Winfree, 1987;Jahnke et al, 1988;Amemiya et al, 1996). Understanding the onset of those exotic phenomena in chemical systems has provided important insight into the formation of similar behaviour in nature (Goldbeter, 1996;Dutt & Menzinger, 1999;Dhanarajan et al, 2002;Carlsson et al, 2006;Chiu et al, 2006).…”
