Informationen zum Autor Bartosz A. Grzybowski is Associate Professor of Chemical and Biological Engineering at Northwestern University in Evanston, Illinois (USA). He was educated at the University of Gdansk (Poland) and Yale University (USA) and gained his PhD at Harvard University (USA), where he also worked as a postdoctoral fellow. From 2001 to 2003, Professor Grzybowski was Director of Research (Concurrent Pharmaceuticals) and Associate of the Department of Chemistry and Chemical Biology at Harvard University. He is the recipient of several awards including the 2003 Camille and Henry Dreyfus New Faculty Award and in 2006 an ACS Division of Colloid and Surface Chemistry Unilever Award and he is the (co)author of over 70 papers. Klappentext Change and motion define and constantly reshape the world around us, on scales from the molecular to the global. In particular, the subtle interplay between chemical reactions and molecular transport gives rise to an astounding richness of natural phenomena, and this often manifests itself in the emergence of intricate spatial or temporal patterns. The underlying theme of this book is that by "setting chemistry in motion" in a proper way, it is not only possible to discover a variety of new phenomena, in which chemical reactions are coupled with diffusion, but also to build micro-/nanoarchitectures and systems of practical importance. Although reaction and diffusion (RD) processes are essential for the functioning of biological systems, there have been only a few examples of their application in modern micro- and nanotechnology. Part of the problem has been that RD phenomena are hard to bring under experimental control, especially when the system's dimensions are small. Ultimately this book will guide the reader through all the aspects of these systems - from understanding the basics to practical hints and then to applications and the interpretation of results. Topics covered include: An overview and outlook of both biological and man-made reaction-diffusion systems. The fundamentals and mathematics of diffusion and chemical reactions. Reaction -diffusion equations and the methods of solving them. 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 solid interfaces. Microstructuring of solids using reaction-diffusion. Reaction-diffusion for chemical amplification and sensing. Reaction-diffusion in three dimensions and at the nanoscale, including nanosynthesis. This book is aimed at all those who are interested in chemical processes at small scales, especially physical chemists, chemical engineers, and material scientists. The book can also be used for one-semester, graduate elective courses in chemical engineering, materials science or chemistry.
