The emergence of nanoscience portends a revolution in technology that will soon impact virtually every facet of our technological lives. Yet there is little understanding among the educated public on what it is, and no basic textbooks on the subject exist. This book bridges the gap between the detailed, research-level treatments and the generalities of "popular science" books, introducing the subject in a manner accessible to engineers and scientists outside the field as well as to undergraduate students. After a basic introduction to the subject, the authors explore topics that include molecular nanotechnology, nanomaterials and nanopowders, nanoelectronics, optics, photonics, solar energy, and nanobiomimetrics.
