This book presents a detailed account on the various physical and chemical properties of carbon nanotubes. These are tube like quasi-one-dimensional structures of nanometer-scale diameter made up of rolled graphene sheets. Over the past two decades, carbon nanotubes have drawn noteworthy attention of chemists, electronic device engineers, material scientists and physicists due to their outstanding electronic, chemical, optical, structural and mechanical properties. Carbon nanotube researches, particularly the ones focusing on industrial applications, are fast becoming more significant. The latest research topics on the structural, electric, physical and chemical properties on carbon nanotubes have been encompassed in this all-inclusive book. Reputed researchers from across the globe have contributed in this book. The aim of this book is to serve as a valuable source of reference for engineers, researchers as well as students engaged in the field of carbon nanotubes.
