Belousov-Zhabotinsky reaction photosensitive

Oscillatory reactions provide one of the most active areas of research in contemporary chemical kinetics and two published studies on the photochemistry of Belousov-Zhabotinsky reaction are very significant in this respect. One deals with Ru(bpy)3 photocatalysed formation of spatial patterns and the other is an analysis of a modified complete Oregonator (model scheme) system which accounts for the O2 sensitivity and photosensitivity. ...

The predictions of the kinematical theory for the resonance of spiral waves were verified in [13,27] by performing a numerical simulation for a particular reaction-diffusion model. The resonance of spiral waves was observed [16] using the photosensitive modification of the Belousov-Zhabotinsky reaction. The annihilation of a pair of spiral waves rotating in opposite directions after the application of periodic resonance illumination was also seen in [16]. 

Spiral waves also arise in the oxidation of carbon-monoxide on platinum surfaces [10]. In 1972 they have been discovered by Winfree [79] in the photosensitive Belousov-Zhabotinsky (BZ) reaction, see for recent investigations for example [83, 84, 87]. Both reactions are studied in the SFB 555. The classical BZ reaction is a catalytic oxidation of malonic acid, using bromate in an acidic environment. Experimentally it exhibits well reproducible drift, meander and chaotic motions of the spiral wave and its tip.
