How Does Mechanical Rotation and Changing Viscosity Affect Pattern Formation in Chemical Clock Reactions?

Abstract

The Belousov-Zhabotinsky (BZ) reaction is an oscillatory chemical reaction where an organic substrate is oxidised by bromate ions in the presence of a transition metal ion, producing complex wave and spiral patterns. External and internal perturbations are known to alter pattern formation, with increasing viscosity slowing diffusion and stabilising wavefronts, while the influence of rotation remains largely unexplored.
