Solar sailing is a topic of growing popular and media interest. Solar sail propulsion will make space exploration more affordable and offer access to destinations within (and beyond) the solar system that are currently beyond our reach. This book describes solar sails, how they work and what they will be used for in the exploration of space in an easily readable manner which does not necessitate any prior knowledge of physics or solar sailing. It discusses current plans for solar sails and also describes how advanced technology, such as nanotechnology, might enhance solar-sail performance. Much has been accomplished recently to make solar sail technology very close to becoming an engineering reality and it will soon be used by the world’s space agencies in the exploration of the solar system and beyond.

The book has four parts, each with multiple chapters which, in turn, contain some references and suggested further reading. Parts 1 - 3 are non-mathematical, while Part 4 contains more detailed technical information.

Part 1 summarizes space propulsion systems and technologies. These are the key to any deep space exploration by humans, robots, or both. Solar-sail propulsion will make space exploration more affordable and offer access to destinations within (and beyond) the solar system that are currently beyond our reach.

Part 2 describes the fundamentals of space solar sail propulsion at a non-mathematical level and will include the near-, mid- and far-term missions that might use solar sails as a propulsion system. Near-term missions will study the sun and will carry artifacts and human DNA into deep space. Mid-term missions will go to the outer solar system and into nearby interstellar space. The far-term missions might be possible with very large, ultra-lightweight sails, possibly using beamed energy from space-based lasers, to carry our first spacecraft to another star.

Part 3 outlines solar sail technology and the construction of current and future sailcraft, including the work of both government and private space organizations. Images of sail hardware that has been built, tested and, in some cases, flown will be included. Part 4 will give a more rigorous explanation of solar sail propulsion (supporting Part 1) and the supporting analysis of the missions and technologies discussed in Parts 2 & 3.

Researchers are interested in the development of modeling methods applied to predicting the atomistic, microscopic and macroscopic response of composite materials under stress and hostile environment. Material behaviors at the macroscale level are controlled by their characteristics at lower scale levels. This fact is even more significant for composite materials. As a result, in order to design and analyze composite structures as well as new composite materials, it is necessary to model material behaviors at different length scales and to couple them. This book presents the state of the art in multiscale modeling and simulation techniques for composite materials and structures. It focuses on the structural and functional properties of engineering composites and the sustainable high performance of components and structures. The multiscale techniques can be also applied to nanocomposites which are important application areas in nanotechnology.

Some of humankind's greatest tools have been forged in the research laboratory. Who could argue that medical advances like antibiotics, blood transfusions, and pacemakers have not improved the quality of people's lives? But with each new technological breakthrough there comes an array of consequences, at once predicted and unpredictable, beneficial and hazardous. Outcry over recent developments in the reproductive and genetic sciences has revealed deep fissures in society's perception of biotechnical progress. Many are concerned that reckless technological development, driven by consumerist impulses and greedy entrepreneurialism, has the potential to radically shift the human condition - and not for the greater good. "Biotechnology and the Human Good" builds a case for a stewardship deeply rooted in Judeo-Christian theism to responsibly interpret and assess new technologies in a way that answers this concern. The authors jointly recognize humans not as autonomous beings but as ones accountable to each other, to the world they live in, and to God. They argue that to question and critique how fields like cybernetics, nanotechnology, and genetics might affect our future is not anti-science, anti-industry, or anti-progress, but rather a way to promote human flourishing, common sense, and good stewardship. A synthetic work drawing on the thought of a physician, ethicists, and a theologian, "Biotechnology and the Human Good" reminds us that although technology is a powerful and often awe-inspiring tool, it is what lies in the heart and soul of who wields this tool that truly makes the difference in our world.

Exploring both commercially available and emerging materials, the Nanomaterials Handbook delves into the unique properties of materials that are realized at the nano level using language familiar to materials scientists. While it offers an in-depth investigation of carbon-based nanomaterials, which are as important to nanotechnology as silicon is to electronics, it goes beyond the usual discussion of nanotubes and nanofibers to consider graphite whiskers, cones and polyhedral crystals, and nanocrystalline diamonds. It also provides significant new information with regard to nanostructured semiconductors, ceramics, metals, biomaterials and polymers, as well as advances in drug delivery.

Even before it was identified as a science and given a name, nanotechnology was the province of the most innovative inventors. In medieval times, craftsmen, ingeniously employing nanometer-sized gold particles, created the enchanting red hues found in the gold ruby glass of cathedral windows. Today, nanomaterials are being just as creatively used to improve old products, as well as usher in new ones. From tires to CRTs to sunscreens, nanomaterials are becoming a part of every industry.

The Nanomaterials Handbook provides a comprehensive overview of the current state of nanomaterials. Employing terminology familiar to materials scientists and engineers, it provides an introduction that delves into the unique nature of nanomaterials. Looking at the quantum effects that come into play and other characteristics realized at the nano level, it explains how the properties displayed by nanomaterials can differ from those displayed by single crystals and conventional microstructured, monolithic, or composite materials.

The introduction is followed by an in-depth investigation of carbon-based nanomaterials, which are as important to nanotechnology as silicon is to electronics. However, it goes beyond the usual discussion of nanotubes and nanofibers to consider graphite whiskers, cones and polyhedral crystals, and nanocrystalline diamonds. It also provides significant new information with regard to nanostructured semiconductors, ceramics, metals, biomaterials, and polymers, as well as nanotechnology's application in drug delivery systems, bioimplants, and field-emission displays.

The Nanomaterials Handbook is edited by world-renowned nanomaterials scientist Yury Gogotsi, who has recruited his fellow-pioneers from academia, national laboratories, and industry, to provide coverage of the latest material developments in America, Asia, Europe, and Australia.

In the past, insecticide development has been guided mostly by chemo-rational and bio-rational design based on understanding of the physiology and ecology of insects and crops. A limitation in each new class of compounds is the evolution of resistance in populations of key pests, which ultimately leads to control failures. This phenomenon and the desire to produce more selective and biorational compounds serve as the driving force to develop advanced technologies for insecticide design. Among the highlights of this book are the use of nanotechnology to increase potency of available insecticides, the use of genetic engineering techniques for controlling insect pests, the development of novel insecticides that bind to unique biochemical receptors, the exploration of natural products as a source for environmentally acceptable insecticides, and the use of insect genomics and cell lines for determining biological and biochemical modes of action of new insecticides.
