Nanoengineering involves the engineering and manufacturing of materials at the nanoscale level. Traditional properties of materials are fundamentally altered at the molecular level. Nanomaterials are used in the manufacture of sensors, microfluids, thermoelectrics, photovoltaics, biomedical devices, etc. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in this field. It is meant for students who are looking for an elaborate reference text on nanoengineering.
