Nano and its Future in Industry

The twenty-first century, the century of nanotechnology, is considered the most important era of industry. The nano century is called the century of health, economy and peace. Nano is neither a substance nor an object, it is only a scale, the reduction of a scale, nano is one billionth of a meter, so small that it cannot be seen, but with a very big impact on human life. In the nano scale, the physical, chemical and biological properties of individual atoms, molecules are different from the properties of the mass of matter. Nanoparticles in such a scale and unique characteristics cause the emergence of new achievements in medical and engineering sciences. This book has a five chapters including: Chapter I (An Introduction to Nanotechnology), Chapter II (Nanotechnology in the Oil Industry), Chapter III (Health, Safety, and Environmental Aspects in Nano), Chapter IV (Future Directions and Challenges), Chapter V (The future of Nanotechnology in Industry).We hope that this book will be available to students and those interested in this field as an important scientific resource.
