NEW APPROACHES TO CHEMICAL-PATTERNS

Approximately 40 years ago, Alan Turing predicted that the coupling of diffusion to complex chemical kinetics could give rise to the spontan eous development of chemical patterns. Several challenges have stood i n the way of the experimental realisation of this prediction, but thes e have recently been overcome. Several new experimental configurations for studying the progress of reactions in space and time are now avai lable to the chemist.
