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 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 interpretation of results. <p> <p> Topics covered include: <ul> <li>An overview and outlook of both biological and man-made reaction-diffusion systems. <li>The fundamentals and mathematics of diffusion and chemical reactions. <li>Reaction-diffusion equations and the methods of solving them. <li>Spatial control of reaction-diffusion at small scales. <li>Micro- and nanofabrication by reaction-diffusion. <li>Chemical clocks and periodic precipitation structures. <li>Reaction-diffusion in soft materials and at solid interfaces. <li>Microstructuring of solids using RD. <li>Reaction-diffusion for chemical amplification and sensing. <li>RD in three dimensions and at the nanoscale, including nanosynthesis. </ul> <p> <p> 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 classes.
This volume covers a wide range of adsorption activities of porous carbon (PC), CNTs, and carbon nano structures that have been employed so far for the removal of various pollutants from water, wastewater, and organic compounds. The low cost, high efficiency, simplicity, and ease in the upscaling of adsorption processes using PC make the adsorption technique attractive for the removal and recovery of organic compounds. The activated carbon modification process has also been of interest to overcome some of the limitations of the adsorbents.
Due to a large specific surface area, and small, hollow, and layered structures, CNTs and carbon nano structures have been investigated as promising adsorbents for various metal ions. Inorganic and organic pollutants can be easily modified by chemical treatment to increase their adsorption capacity. There is the huge hope that nanotubes applications will lead to a cleaner and healthier environment. A brief summary of these modeling methods is reviewed in this volume.
Also, two important simulation methods, the Monte Carlo and the Molecular Dynamic, are included in this volume. The presence of micro and mesopores is essential for many researchers aiming to control micro or mesoporosity. The present volume attempts to give a general view of the recent activities on the study of pore structure control, with application novel simulation and modeling methods and the necessity and importance of this controlling. This volume also provides a brief overview of the methodology and modeling beside simulation methods for characterization of nanoporous carbons by using adsorption isotherm parameters.
Does humanity have a moral obligation to emphasize nanotechnology's role in addressing the critical public health and environmental problems of our age? This well crafted book explores this idea by analyzing the prospects for a macroscience nanotechnology-for-environmental sustainability project in areas such as food, water and energy supply, medicine, healthcare, peace and security. Developing and applying an innovative science-based view of natural law underpinning a global social contract, it considers some of the key scientific and governance challenges such a global project may face. The book concludes that the moral culmination of nanotechnology is a Global Artificial Photosynthesis (GAP) project. It argues that the symmetric patterns of energy creating photosynthesis, life and us, are shaping not only the nanotechnological advances of artificial photosynthesis, but also the ethical and legal norms likely to best govern such scientific achievements to form a sustainable existence on this planet. Nanotechnology for a Sustainable World will appeal to many generations of scientists and policymakers working to improve our world in public health, environmental sustainability and renewable energy and nanotechnology. It will also be a valuable resource for similarly motivated students of chemistry, physics, biology, nanotechnology, photosynthesis, as well as environmental and energy ethics, law and policy.
