The “Nanotechnology Safety” book is one of the first and most diverse books to be published in nanotechnology and nanoscience for the research, development, manufacturing, transportation, storage, handling, as well as educational and training purposes. Nanotechnology has a great potential to become the promising technology of this century because of its outstanding mechanical, electrical (conductive and semiconductive), optical, magnetic, quantum mechanics, and thermal properties of nanotechnology products. These unique properties of nanoscale materials, such as nanoparticles, nanotubes, nanowires, nanofibers, nanocomposites, nanopores, and nanofilms, allow them to be the next generation of materials/devices in many industries such as aerospace, automobile, ship, electronics, medicine, pharmacy, construction, energy, defense, food, and many others.
