In Nanoweapons Louis A. Del Monte describes the most deadly generation of military weapons the world has ever encountered. With dimensions one-thousandth the diameter of a single strand of human hair, this technology threatens to eradicate humanity as it incites world governments to compete in the deadliest arms race ever.  Del Monte predicts that nanoweapons will dominate the battlefield of the future and will help determine the superpowers of the twenty-first century. He traces the emergence of nanotechnology, discusses the current development of nanoweapons--such as the "mini-nuke," which weighs five pounds and carries the power of one hundred tons of TNT--and offers concrete recommendations for controlling their proliferation and avoiding human annihilation.

The scientific knowledge of nanoscience and nanotechnology is regarded to be a modern sciencethat evolved after Feynman's concept was formulated in the 1950s. However, Faraday and other scientists in the 19th century showed the science behind the small and its relation to optical properties. And it is now accepted that knowledge of using nanoparticles prevailed during the medieval period as well. This book takes the readers on a fascinating journey writing the history of nanotechnology based on the evidence of existence from the prehistoric period right up to the contemporary times.  Nature utilized nanotechnology during the origin and expansion of the universe and especially in the evolution of living beings on our planet. Early civilizations in different parts of globe fabricated and used materials without having perception of their actual size. This unique historical view systematically evaluates the development of various applications of nanotechnology through the ages and the science behind it. Some of the issues covered include: * How old is nanotechnology? * Pre-historic evidence of knowledge of nanotechnology * Nanotechnology in ancient India * Ayurvedic Bhasma as nanomedicine  * Mayan's knowledge of nanotechnology * Nanotechnology during the Roman empire and medieval period * European knowledge in the 19th century * Modern and contemporary history of nanotechnology This book is compilation of existence of scientific knowledge even of the people who existed before there were schools, universities and organized teaching. The author has scoured literature dating back to Mayan ... as well as historical observations A systematic evaluation of development of various applications of nanotechnology and the science behind it is presented in this book under following headings -How old is Nanotechnology -Pre-historic Evidence of Knowledge of Nanotechnology -Nanotechnology in Ancient India -Ayurvedic Bhasma as Nanomedicine, its use prevails even today  -Mayan's Knowledge of Nanotechnology -Nanotechnologists Flourished During Roman Empire and medieval period -European Nano knowledge That Led to Faraday Understands of Gold Nanoparticles -Contemporary History of Nanotechnology

Should you adopt nanotechnology? If you have already adopted it, what do you need to know? What are the risks? Nanomaterials and nanotechnologies are revolutionizing the ways we treat disease, produce energy, manufacture products, and attend to our daily wants and needs. To continue to capture the promise of these transformative products, however, we need to ask critical questions about the broader impacts of nanotechnology on society and the environment. Exploring these questions, the second edition of Nanotechnology: Health and Environmental Risks gives you the latest tools to understand the risks of nanotechnology and make better decisions about using it. Examining the state of the science, the book discusses what is known, and what still needs to be understood, about nanotechnology risk. It looks at the uses of nanotechnology for energy, industry, medicine, technology, and consumer applications and explains how to determine whether there is risk--even when there is little reliable evidence--and how to manage it. Contributors cover a wide range of topics, including: Current concerns, among them perceived risks and the challenges of evaluating emerging technology A historical perspective on product safety and chemicals policy The importance of being proactive about identifying and managing health and environmental risks during product development How the concepts of sustainability and life cycle assessment can guide nanotechnology product development Methods for evaluating nanotechnology risks, including screening approaches and research How to manage risk when working with nanoscale materials at the research stage and in occupational environments What international organizations are doing to address risk issues How risk assessment can inform environmental decision making Written in easy-to-understand language, without sacrificing complexity or scientific accuracy, this book offers a wide-angle view of nanotechnology and risk. Supplying cutting-edge approaches and insight, it explains what types of risks could exist and what you can do to address them. What's New in This Edition Updates throughout, reflecting advances in the field, new literature, and policy developments A new chapter on nanotechnology risk communication, including insights into risk perceptions and the mental models people use to evaluate technological risks An emphasis on developing nanotechnology products that are sustainable in the long term Advances in the understanding of nanomaterials toxicity Cutting-edge research on occupational exposure to nanoparticles Changes in the international landscape of organizations working on the environmental, health, and safety aspects of nanotechnologies
