Abstract
Experimental evidence for the spontaneous formation of spiral waves an d crossing wave patterns for the Belousov-Zhabotinsky reaction in solu tion are presented. Also observed are so-called 'lateral instabilities ' with the spontaneous deformation of circular fronts in systems of lo w excitability. Lateral instabilities in resin-based systems, with the redox catalyst immobilised on ion-exchange beads, and the effect of t he ageing of solutions, are also reported.
