Reaction-Diffusion Fronts in Complex Structures

In the earlier chapter we have discussed the formation of colour bands in moving wave fronts, stationary structures which are governed by coupling of reaction and diffusion. In this chapter we will be concerned with pattern formation governed by the process of mass flow and diffusion related to precipitation as crystals, electro-deposits, bacterial colonies and diffusion. Just as in the former case, in the present case also we come across very complex patterns, depending on the experimental conditions. However in the present case it is possible to rationalize the complex structure with use of new mathematical concepts of fractal geometry. [Pg.235]
