Research at the nanoscale and the new technologies being developed are evolving much too rapidly to provide a complete picture of the field. Instead, the second edition of this enormously popular and bestselling handbook presents a wide snapshot of the current state of the art, including basic concepts, current challenges, and advanced research results. Along with 18 revised chapters, this second edition also features 24 brand new chapters that cover such topics as applications of spintronic devices, optoelectronics, DNA-based computing, ordered carbon nanotube architectures, nanocomposities, and bio-molecular motors. It also includes a full color insert as well as numerous illustrations and references.
