Book excerpt: Public institutions, academic researchers and financial analysts among others hail nanotechnologies as one of the most promising sectors of social and economic development. Calculations predict that it will become a trillion euro industry by 2015 and that it will bring about economic change of at least the same magnitude as the industrial revolution. Nanotechnology is recent, younger by some thirty years than biotechnology, but it appears at a point in time in human history where there is a convergence between the globalization of access to information and increasing awareness of the importance of sustainable development. Nanotechnology and Sustainable Development explores the ways in which this convergence leads to a change in the management of innovation âe" and ultimately a reshaping of technological democracy. The scope of the study is global, with a particular focus on Europe and the United States, utilizing several case studies of stakeholders including entrepreneurs, commentators, end users, scientists, and policy makers.

Book excerpt: This volume presents a comprehensive perspective on the global scientific, technological, and societal impact of nanotechnology since 2000, and explores the opportunities and research directions in the next decade to 2020. The vision for the future of nanotechnology presented here draws on scientific insights from U.S. experts in the field, examinations of lessons learned, and international perspectives shared by participants from 35 countries in a series of high-level workshops organized by Mike Roco of the National Science Foundation (NSF), along with a team of American co-hosts that includes Chad Mirkin, Mark Hersam, Evelyn Hu, and several other eminent U.S. scientists. The study performed in support of the U.S. National Nanotechnology Initiative (NNI) aims to redefine the R&D goals for nanoscale science and engineering integration and to establish nanotechnology as a general-purpose technology in the next decade. It intends to provide decision makers in academia, industry, and government with a nanotechnology community perspective of productive and responsible paths forward for nanotechnology R&D.

A major section of the world population is struggling for drinking water. Polluted soil is resulting into low agricultural productivity and thus creating challenges in the way of sustainable livelihood of a large section of human population. Biological treatment can offer both green solutions for wastewater treatment and resource recovery as well. Like algal-based systems can be utilized for wastewater treatment and production of biofuels from the biomass grown on the wastewater. Bio-based nanomaterials have been extensively studied for their employability in the health care, process optimization, water resource management, dealing with environmental pollutants, biosensors, and many others. Bioprospecting of novel biological agents, bio-based products, and bioresource recovery are paving the way for sustainable development as they are providing local solutions for a number of problems. In this proposed book, we start with the introduction to bio-nanotechnological principles and later on discuss bio-based nanomaterials employability for a diverse range of applications from environment to energy to health care. This book provides with current trends in bio-nanotechnology for anthropogonic purposes, prospects, challenges, and way forward.

Book excerpt: 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
