This report discusses the different types of styrenic copolymers available in the market place today, their properties and applications. The market situation is discussed. The chemistry of these materials is outlined, together with a summary of manufacturing methods. The morphology, manufacture and properties of key materials are described. This review is accompanied by summaries of the cited papers from the Rapra Polymer Library database.
This review describes the process of life cycle analysis in some detail. It describes the different organisations involved in researching and applying these techniques and the database resources being used to generate comparative reports. The overview explains the factors to be considered, the terminology, the organisations involved in developing these techniques and the legislation which is driving the whole process forward. The ISO standards relating to environmental management are also discussed briefly in the document. Design for the environment is covered in the report. This review is accompanied by summaries of selected papers on life cycle analysis and environmental impact from the Rapra Polymer Library database.
This book is an upb306d and expanded version of the course notes for the Composite Awareness course run by the Warwick Manufacturing Group in 1998-1999. The book gives readers an appreciation of composites, materials properties, manufacturing technologies and the wider implications of using composites in the automotive sector. It will be useful for those already working with composites in automotive applications and for those who are considering using them in the future.
What does cotton candy, which dissolves at the touch, have in common with Kevlar, used for bullet-proof vests? How can our understanding of such materials help us to tackle essential problems of the 21st century? Materials play a key role in our search for solutions to many pressing issues. They underpin many industries, are critical for the development of consumer goods, are essential components of medical diagnostic techniques, offer hope for the treatment of currently incurable diseases, and provide answers to environmental problems. This handbook is a guide to the materials we rely on for the future. Materials for the 21st Century serves as a useful resource for undergraduate and high school students preparing for a career in physical sciences, life sciences,or engineering, by helping them to identify new areas of interest. It is also an excellent reference for readers interested in learning more about the diverse range of materials that underlie key aspects of our economy and everyday lives.
“This eloquent, elegant book thoughtfully plumbs the . . . consequences of our dependence on plastics” (The Boston Globe, A Best Nonfiction Book of 2011). From pacemakers to disposable bags, plastic built the modern world. But a century into our love affair, we’re starting to realize it’s not such a healthy relationship. As journalist Susan Freinkel points out in this eye-opening book, we’re at a crisis point. Plastics draw on dwindling fossil fuels, leach harmful chemicals, litter landscapes, and destroy marine life. We’re drowning in the stuff, and we need to start making some hard choices. Freinkel tells her story through eight familiar plastic objects: a comb, a chair, a Frisbee, an IV bag, a disposable lighter, a grocery bag, a soda bottle, and a credit card. With a blend of lively anecdotes and analysis, she sifts through scientific studies and economic data, reporting from China and across the United States to assess the real impact of plastic on our lives. Her conclusion is severe, but not without hope. Plastic points the way toward a new creative partnership with the material we love, hate, and can’t seem to live without. “When you write about something so ubiquitous as plastic, you must be prepared to write in several modes, and Freinkel rises to this task. . . . She manages to render the most dull chemical reaction into vigorous, breathless sentences.” —SF Gate “Freinkel’s smart, well-written analysis of this love-hate relationship is likely to make plastic lovers take pause, plastic haters reluctantly realize its value, and all of us understand the importance of individual action, political will, and technological innovation in weaning us off our addiction to synthetics.” —Publishers Weekly “A compulsively interesting story. Buy it (with cash).” —Bill McKibben, author of The End of Nature “What a great read—rigorous, smart, inspiring, and as seductive as plastic itself.” —Karim Rashid, designer
Along comes a global pandemic coronavirus, COVID-19, and our world is turned upside down. Can the idea of samsara shed any light on all this terrible suffering, turmoil and change? Are we all travelling around the ever-turning cycle of samsara, being born, dying, then reborn - again, and again, and again? Does our life, the things that happen to us, and our death, have any meaning? What do Hinduism, Buddhism, and samsara tell us about suffering, life and death? Could spiritual dimensions exist or do we live in a purely material universe? What is consciousness and does it die when our bodies die? Are rebirth or reincarnation even possible? Can we have spirituality without religion? What, if anything, might spirituality or religion mean in a turbulent and unpredictable twenty-first century? Do mysticism, psychedelics, science and quantum physics offer clues to any of these questions? Take a journey with the author through the fascinating cultures of Nepal, India, Bali and Cambodia and explore their rich traditions of Hinduism, Buddhism and samsara. Part exploration of spirituality and religion, part travel adventure to places of astonishing diversity, this book will get you thinking about your own beliefs, life and death, and where those might fit in to a bigger picture.
