Change and motion define and constantly reshape the world aroundus, on scales from the molecular to the global. In particular, thesubtle interplay between chemical reactions and molecular transportgives rise to an astounding richness of natural phenomena, andoften manifests itself in the emergence of intricate spatial ortemporal patterns. The underlying theme of this book is that by"setting chemistry in motion" in a proper way, it isnot only possible to discover a variety of new phenomena, in whichchemical reactions are coupled with diffusion, but also to buildmicro-/nanoarchitectures and systems of practical importance.Although reaction and diffusion (RD) processes are essential forthe functioning of biological systems, there have been only a fewexamples of their application in modern micro- and nanotechnology.Part of the problem has been that RD phenomena are hard to bringunder experimental control, especially when the system'sdimensions are small. Ultimately this book will guide the readerthrough all the aspects of these systems - from understandingthe basics to practical hints and then to applications andinterpretation of results.

Topics covered include:
* An overview and outlook of both biological and man-madereaction-diffusion systems.
* The fundamentals and mathematics of diffusion and chemicalreactions.
* Reaction-diffusion equations and the methods of solvingthem.
* Spatial control of reaction-diffusion at small scales.
* Micro- and nanofabrication by reaction-diffusion.
* Chemical clocks and periodic precipitation structures.
* Reaction-diffusion in soft materials and at solidinterfaces.
* Microstructuring of solids using RD.
* Reaction-diffusion for chemical amplification and sensing.
* RD in three dimensions and at the nanoscale, includingnanosynthesis.

This book is aimed at all those who are interested in chemicalprocesses at small scales, especially physical chemists, chemicalengineers, and material scientists. The book can also be used forone-semester, graduate elective courses in chemical engineering,materials science, or chemistry classes.

"In summary, this text can be viewed as a first stepping stone intothe reaction-diffusion field. It is a quick, informative survey ofwhat types of syntheses are possible in reaction-diffusion systems;it provides the necessary framework to begin an in-depth project inthe field; and most importantly, it is an enjoyable read."(Angewandte Chemie, 2010)
