Titelbeschreibung

This book describes various aspects of nanoscience and nanotechnology. It begins with an introduction to nanoscience and nanotechnology and includes a historical prospective, nanotechnology working in nature, man -made nanomaterial and impact of nanotechnology illustrated with examples. It goes on to describes general synthetic approaches and strategies and also deals with the characterization of nanomaterial using modern tools and techniques to give basic understanding to those interested in learning this emerging area. It then deals with different kinds of nanomaterial such as inorganics, carbon based-, nanocomposites and self-assembled/supramolecular nano structures in terms of their varieties, synthesis, properties etc. In addition, it contains chapters devoted to unique properties with mathematical treatment wherever applicable and the novel applications dealing with information technology, pollution control (environment, water), energy, nanomedicine, healthcare, consumer goods etc.

Back cover copy

Provides a basic understanding of the complex and revolutionary disciplines of nanoscience and nanotechnology The fields of nanoscience and nanotechnology are growing exponentially as their potential to solve medical and environmental problems becomes clear. However, unless budding scientists remain educated and up to date on the most recent advances in nanoscience, this growth cannot continue. Essentials in Nanoscience and Nanotechnology combats this problem. Kumar and Kumbhat have assembled a comprehensive and concise text that both introduces the properties and reactions of molecules at the nanoscale and provides detailed information on recent advances, all while remaining comprehensible to someone only just setting foot in the field. Its broad coverage includes the following: <ul> <li>The history of nanoscience and nanotechnology</li> <li>Synthesis, properties, and characterization of nanomaterials</li> <li>Specific nanomaterials such as nanocomposites, carbon-based nanomaterials, supramolecular nanomaterials, and nanocoatings</li> <li>Applications in medicine, healthcare, drug discovery and delivery, electronics, defense, energy, and the environment</li> <li>Toxicity and ethics of nanotechnology use</li> </ul> Students of all levels, young professionals, researchers, and anyone else wishing to gain an understanding of the principles of nanoscience and nanotechnology as well as their latest developments will find this book an invaluable resource.
