This book mainly focuses on nano engineering in terms of its fundamental and applications, nanoscience instruments, nano-electromagnetic systems, nanomechanics, nanomachines and self-assembly. This important book provides a vivid introduction to the procedures, techniques, problems and difficulties of computational nano-engineering and design. The book provides step by step scientific background information, for an easy reconstruction of the explanations. The focus of this book laid down on the molecular dynamics method, which is well suited for explaining the topic to the reader with just a basic knowledge of physics. Results and conclusions of detailed nano-engineering studies are presented in an instructive style.
