Chemical Waves

In our paper we try to describe the basic concepts
of chemical waves and spatial pattern formation
in a simple way. We pay particular attention to self-organisation
phenomena in extended excitable systems.
These result in the appearance of travelling waves,
spiral waves, target patterns, Turing structures or more
complicated structures called scroll waves, which are
three-dimensional systems. We describe the most
famous oscillating reaction, the Belousov–Zhabotinsky
(BZ) reaction, in greater detail. This is because it is of
great interest in both physical chemistry and in studies
on the evolution and sustenance of self-organising biological
systems.
