Device and Materials Modeling in PEM Fuel Cells
by Stephen J. Paddison Keith S. PromislowThe impact of proton exchange membrane (PEM) fuel cells on energy generation will parallel the impact of the integrated circuit on information technology. The underlying processes in PEM fuel cells have strong ties to energy generation at the mitochondrial level in organic life. The potential applications range from the micron scale to large scale industrial production. Successful integrated of PEM fuel cells into the mass-market will require new materials and a deepening understanding of the balance required to maintain the various operational states. Key areas of development include electrocatalysts for the fuel and air electrodes and membranes exhibiting good proton conductivity under minimal hydration and temperatures between -20 °C to 120 °C. New materials possessing improved properties will emerge as a result of a collaborative effort between experimentalists, engineers, and theorists, the latter doing both device and materials modeling. This book presents a series of contributed articles from scientists who have made a contribution in the modeling of fuel cells from either a device or materials perspective. As fuel cell technologies are an emerging area this book will be of interest to any working in this field. This book will provide a survey (with significant depth) of virtually all the computational and modeling work done in this area.
Device Applications of Silicon Nanocrystals and Nanostructures
by Nobuyoshi KoshidaRecent developments in the technology of silicon nanocrystals and silicon nanostructures, where quantum-size effects are important, are systematically described including examples of device applications. Due to the strong quantum confinement effect, the material properties are freed from the usual indirect- or direct-bandgap regime, and the optical, electrical, thermal, and chemical properties of these nanocrystalline and nanostructured semiconductors are drastically changed from those of bulk silicon. In addition to efficient visible luminescence, various other useful material functions are induced in nanocrystalline silicon and periodic silicon nanostructures. Some novel devices and applications, in fields such as photonics (electroluminescence diode, microcavity, and waveguide), electronics (single-electron device, spin transistor, nonvolatile memory, and ballistic electron emitter), acoustics, and biology, have been developed by the use of these quantum-induced functions in ways different from the conventional scaling principle for ULSI.
Device Architecture and Materials for Organic Light-Emitting Devices
by Sarah ScholsDevice Architecture and Materials for Organic Light-Emitting Devices focuses on the design of new device and material concepts for organic light-emitting devices, thereby targeting high current densities and an improved control of the triplet concentration. A new light-emitting device architecture, the OLED with field-effect electron transport, is demonstrated. This device is a hybrid between a diode and a field-effect transistor. Compared to conventional OLEDs, the metallic cathode is displaced by one to several micrometers from the light-emitting zone, reducing optical absorption losses. The electrons injected by the cathode accumulate at an organic heterojunction and are transported to the light-emission zone by field-effect. High mobilities for charge carriers are achieved in this way, enabling a high current density and a reduced number of charge carriers in the device. Pulsed excitation experiments show that pulses down to 1 µs can be applied to this structure without affecting the light intensity, suggesting that pulsed excitation might be useful to reduce the accumulation of triplets in the device. The combination of all these properties makes the OLED with field-effect electron transport particularly interesting for waveguide devices and future electrically pumped lasers. In addition, triplet-emitter doped organic materials, as well as the use of triplet scavengers in conjugated polymers are investigated.

Device Free Weekend
by Sean DoolittleSeven friends, one eccentric billionaire, and an all-expenses-paid reunion on a private island: with no technology allowed, it&’ll be a weekend to remember—for those who make it out alive. Ryan Cloverhill, founder and CEO of the world&’s most popular social media platform, invites his six best friends from college to his home on his private island near Puget Sound. For Stephen, Emma, Perry, Will, Beau, and Lainie, day one is just what the doctor ordered: amazing food, many drinks, lots of laughter, and a sunset cruise around the island aboard their host&’s custom Van Dutch 55. Day Two, however, takes a bewildering turn when the six hungover guests wake up to find that their host has disappeared, along with all connection to the mainland. A touchscreen tablet of unknown make awaits them, blatantly defying the rules of the weekend with its on-screen challenge: Unlock Me! The passcode to the tablet is hidden somewhere in the group&’s shared history. But what seems at first like just another silly game turns deadly serious when the group discovers what unlocking the tablet really means. Is it the key to their futures, a Pandora&’s box none of them will ever be able to close, or both? Only one thing is clear: their old friend Ryan has something unthinkable planned. Now it&’s up to the six of them to stop him. And when this weekend is over, the world will never be the same.
Device-Level Modeling and Synthesis of High-Performance Pipeline ADCs
by Jesús Ruiz-Amaya Ángel Rodríguez-Vázquez Manuel Delgado-RestitutoThis book presents models and procedures to design pipeline analog-to-digital converters, compensating for device inaccuracies, so that high-performance specs can be met within short design cycles. These models are capable of capturing and predicting the behavior of pipeline data converters within less than half-a-bit deviation, versus transistor-level simulations. As a result, far fewer model iterations are required across the design cycle. Models described in this book accurately predict transient behaviors, which are key to the performance of discrete-time systems and hence to the performance of pipeline data converters.

Devices of the Soul: Battling for Our Selves in an Age of Machines
by Steve Talbott"Self-forgetfulness is the reigning temptation of the technological era. This is why we so readily give our assent to the absurd proposition that a computer can add two plus two, despite the obvious fact that it can do nothing of the sort--not if we have in mind anything remotely resembling what we do when we add numbers. In the computer's case, the mechanics of addition involve no motivation, no consciousness of the task, no mobilization of the will, no metabolic activity, no imagination. And its performance brings neither the satisfaction of accomplishment nor the strengthening of practical skills and cognitive capacities."In this insightful book, author Steve Talbott, software programmer and technical writer turned researcher and editor for The Nature Institute, challenges us to step back and take an objective look at the technology driving our lives. At a time when 65 percent of American consumers spend more time with their PCs than they do with their significant others, according to a recent study, Talbott illustrates that we're forgetting one important thing--our Selves, the human spirit from which technology stems.Whether we're surrendering intimate details to yet another database, eschewing our physical communities for online social networks, or calculating our net worth, we freely give our power over to technology until, he says, "we arrive at a computer's-eye view of the entire world of industry, commerce, and society at large...an ever more closely woven web of programmed logic."Digital technology certainly makes us more efficient. But when efficiency is the only goal, we have no way to know whether we're going in the right or wrong direction. Businesses replace guiding vision with a spreadsheet's bottom line. Schoolteachers are replaced by the computer's dataflow. Indigenous peoples give up traditional skills for the dazzle and ease of new gadgets. Even the Pentagon's zeal to replace "boots on the ground" with technology has led to the mess in Iraq. And on it goes.The ultimate danger is that, in our willingness to adapt ourselves to technology, "we will descend to the level of the computational devices we have engineered--not merely imagining ever new and more sophisticated automatons, but reducing ourselves to automatons."To transform our situation, we need to see it in a new and unaccustomed light, and that's what Talbott provides by examining the deceiving virtues of technology--how we're killing education, socializing our machines, and mechanizing our society.Once you take this eye-opening journey, you will think more clearly about how you consume technology and how you allow it to consume you."Nothing is as rare or sorely needed in our tech-enchanted culture right now as intelligent criticism of technology, and Steve Talbott is exactly the critic we've been waiting for: trenchant, sophisticated, and completely original. Devices of the Soul is an urgent and important book."--Michael Pollan, author of The Omnivore's Dilemma: A Natural History of Four Meals and The Botany of Desire: A Plant's Eye View of the World"Steve Talbott is a rare voice of clarity, humanity, and passion in a world enthralled by machines and calculation. His new book, Devices of the Soul, lays out a frightening and at the same time inspiring analysis of what computers and computer-like thinking are doing to us, our children, and the future of our planet. Talbott is no Luddite. He fully understands and appreciates the stunning power of technology for both good and evil. His cool and precise skewering of the fuzzy thinking and mindless enthusiasm of the technology true believers is tempered by his modesty, the elegance of his writing, and his abiding love for the world of nature and our capacity for communion with it. "--Edward Miller, Former editor, Harvard Education Letter"Those who care about the healthy and wholesome lives of children can gain much from Steve Talbott's wisdom. He examines the need to help children spe

The Devil's Element: Phosphorus And A World Out Of Balance
by Dan EganA New Yorker Best Book of the Year "Lively…and thought-provoking.” —Robert W. Howarth, Science The New York Times best-selling author on the source of great bounty—and now great peril—all over the world. Phosphorus has played a critical role in some of the most lethal substances on earth: firebombs, rat poison, nerve gas. But it’s also the key component of one of the most vital: fertilizer, which has sustained life for billions of people. In this major work of explanatory science and environmental journalism, Pulitzer Prize finalist Dan Egan investigates the past, present, and future of what has been called “the oil of our time.” The story of phosphorus spans the globe and vast tracts of human history. First discovered in a seventeenth-century alchemy lab in Hamburg, it soon became a highly sought-after resource. The race to mine phosphorus took people from the battlefields of Waterloo, which were looted for the bones of fallen soldiers, to the fabled guano islands off Peru, the Bone Valley of Florida, and the sand dunes of the Western Sahara. Over the past century, phosphorus has made farming vastly more productive, feeding the enormous increase in the human population. Yet, as Egan harrowingly reports, our overreliance on this vital crop nutrient is today causing toxic algae blooms and “dead zones” in waterways from the coasts of Florida to the Mississippi River basin to the Great Lakes and beyond. Egan also explores the alarming reality that diminishing access to phosphorus poses a threat to the food system worldwide—which risks rising conflict and even war. With The Devil’s Element, Egan has written an essential and eye-opening account that urges us to pay attention to one of the most perilous but little-known environmental issues of our time.
The Devil's Fruit: Farmworkers, Health, and Environmental Justice (Medical Anthropology)
by Dvera I. SaxtonThe Devil's Fruit describes the facets of the strawberry industry as a harm industry, and explores author Dvera Saxton’s activist ethnographic work with farmworkers in response to health and environmental injustices. She argues that dealing with devilish—as in deadly, depressing, disabling, and toxic—problems requires intersecting ecosocial, emotional, ethnographic, and activist labors. Through her work as an activist medical anthropologist, she found the caring labors of engaged ethnography take on many forms that go in many different directions. Through chapters that examine farmworkers’ embodiment of toxic pesticides and social and workplace relationships, Saxton critically and reflexively describes and analyzes the ways that engaged and activist ethnographic methods, frameworks, and ethics aligned and conflicted, and in various ways helped support still ongoing struggles for farmworker health and environmental justice in California. These are problems shared by other agricultural communities in the U.S. and throughout the world.

Devil's Plaything
by Matt Richtel“Smart, captivating, sophisticated; I can’t say enough about this deftly told story.”—Steve Berry, New York Times bestselling author of The Emperor’s Tomb“A brilliant thriller that defies genre and scope; a twisted blend of Michael Crichton and Alfred Hitchcock.”—James Rollins, New York Times bestselling author of Altar of EdenA Pulitzer Prize winner for Journalism in 2010, New York Times science reporter Matt Richtel delivers a phenomenal “neuro-tech” thriller about a dark and insidious plot to reengineer the human brain. Devil’s Plaything is smart, fast, and terrifyingly plausible—a page-turner of the first order from the critically acclaimed author of Hooked, whom author David Liss (The Devil’s Company) calls, “The absolute master of crafting amazing fiction around cutting edge science.”
