The future applications of nanotechnology in high-tech industries require deep understanding of the theoretical and computational aspects of all kinds of materials and devices at a nanometer scale. Handbook of Theoretical and Computational Nanotechnology is the first single reference source ever published in field that offer such a unified approach to a wide range of topics dealing with theory, modeling and simulations of nanostructured materials and nanodevices, quantum computing, computational chemistry, physics and biology, nanomechanics, nanomachines, nanoelectronics, nanoprocesses, nanomagnetism, nano-optics, nanomedicines, nanobiotechnology, etc. This 10-volume handbook provides the first ideal introduction and an up-to-date survey of the fascinating new developments and interdisciplinary activities in the whole field presented by scientists working in different subject areas. This handbook is the most profound publication on the topic.The following sections covers the most important and innovative research areas of the nanotechnology: Computational Biology - DNA, enzymes, proteins, biomechanism, neuro-genetic information processing, nanomedicines Computational Chemistry - quantum chemistry, molecular design, methods, chemical reactions, drugs and design Computational methods and Simulation Techniques from ab initio to multiscale, modeling, algorithms, design Materials Behavior at the Nanoscale such as mechanics, defects, diffusion, transport, dynamics, cascades, irradiation Nanoscale Processes - membranes, pores, diffusion, grows, friction, wear, catalysis Nanostructured Materials - metals, composites, polymers, liquid crystals, clusters, quantum dots, colloids, nanotubes Nanostructures - fullerenes, nanotubes, clusters, layers, quantum dots, thin films, surfaces, interfaces Nanoengineering and Nanodesign - nanomachines, nano CAD, nanodevices, logic circuits Nanoelectronics - molecular and computational nanoelectronics, nanodevices, electronic states, quantum dots, nanowires Nanomagnetism - magnetic properties of nanostructures and nanostructured materials Nano-optics - optical response theory, nonlinear optical properties, luminescence, photonic crystals, quantum optics Quantum Computers - theoretical aspects, computational methods for simulating quantum computers, devices, algorithms.
