The Wave Lab

The Wave Lab

The newly created wave lab studies excitation waves:  propagating structures observed in many biological, chemical, and physical systems which can be described as a reaction-diffusion wave (an autocatalytic reaction zone propagates via molecular diffusion without mass transport). Examples are the propagation of action potential in a nerve, the spread of electrical depolarization waves on the heart surface (responsible for the heart beat), or a forest fire. All reaction-diffusion systems can be described with similar sets of nonlinear equations and experimentally investigated with a chemical tabletop model system, the Belousov-Zhabotinsky reaction.
