Thin Impedance Vibrators
by Victor A. Katrich Yuriy M. Penkin Sergey L. Berdnik Mikhail V. Nesterenko Victor M. DakhovThe book is devoted to exploring the foundations of the theory of thin impedance vibrator antennas. The text provides a continuation of the classic theory of thin perfectly conducting vibrators. Many consider impedance conception one of the most universal models in the theory of wave processes, as it informs such a wide spectrum of uses in solving practical problems of electrodynamics. This topic provides an opportunity to further search analytical solutions, allowing a simplification of the mathematical formulation of the boundary problem. The theory strives to widen the boundaries of the impedance vibrator antennas application in complex modern radio-and-electronic systems and devices. The results of much original research conducted by the authors will be useful for practicing engineers and designers of antenna and waveguide systems. The book is written in an academic style, and can be used to teach students and post graduates about radiotechnical and radiophysical specialities. The conclusion of the book lists many actual applied problems, which can provide inspiration for several potential PhD projects. Topics covered in this book are: *general questions of the theory of impedance vibrators in the spatial-frequency representation *electromagnetic waves radiation by impedance vibrators in free space and material mediums *electromagnetic waves radiation by impedance vibrators in material mediums over the perfectly conducting plane *electromagnetic waves scattering by irregular impedance vibrators in free space *generalized method of induced electromotive forces for investigation of the characteristics of impedance vibrators *radiation of electromagnetic waves by radial impedance vibrators on the perfectly conducting sphere *electromagnetic waves scattering by impedance vibrators in the rectangular waveguide

Thin Liquid Films
by Ralf BlosseyThis book is a treatise on the thermodynamic and dynamic properties of thin liquid films at solid surfaces and, in particular, their rupture instabilities. For the quantitative study of these phenomena, polymer thin films (sometimes referred to as "ultrathin") have proven to be an invaluable experimental model system. What is it that makes thin film instabilities special and interesting? First, thin polymeric films have an important range of applications. An understanding of their instabilities is therefore of practical relevance for the design of such films. The first chapter of the book intends to give a snapshot of current applications, and an outlook on promising future ones. Second, thin liquid films are an interdisciplinary research topic, which leads to a fairly heterogeneous community working on the topic. It justifies attempting to write a text which gives a coherent presentation of the field which researchers across their specialized communities might be interested in. Finally, thin liquid films are an interesting laboratory for a theorist to confront a well-established theory, hydrodynamics, with its limits. Thin films are therefore a field in which a highly fruitful exchange and collaboration exists between experimentalists and theorists. The book stretches from the more concrete to more abstract levels of study: we roughly progress from applications via theory and experiment to rigorous mathematical theory. For an experimental scientist, the book should serve as a reference and guide to what is the current consensus of the theoretical underpinnings of the field of thin film dynamics. Controversial problems on which such a consensus has not yet been reached are clearly indicated in the text, as well as discussed in a final chapter. From a theoretical point of view, the field of dewetting has mainly been treated in a mathematically 'light' yet elegant fashion, often making use of scaling arguments. For the untrained researcher, this approach is not always easy to follow. The present book attempts to bridge between the 'light' and the 'rigorous', always with the ambition to enhance insight and understanding - and to not let go the elegance of the theory.
Thin Places: A Pilgrimage Home
by Ann ArmbrechtThin Places is an eloquent meditation on what it means to move between cultures and how one might finally come home, a particular paradox in a culture that lacks deep ties to the natural world. During the 1990s, Ann Armbrecht, an American anthropologist, made several trips to northeastern Nepal to research how the Yamphu Rai acquired, farmed, and held onto their land; how they perceived their area's recent designation as a national park and conservation area; and whether-as she believed-they held a wisdom about living on the earth that the industrialized West had forgotten. What Armbrecht found instead were men and women who shared her restlessness, people also driven by the feeling that there must be more to life than they could find in their village. "We each blamed our dissatisfaction on something in the world," she writes, "not something in ourselves or in the stories we told ourselves about that world. If only we lived elsewhere, then we would be at home." Charting Armbrecht's travels in the mountains of Nepal and in the United States and her disintegrating marriage back home, Thin Places is ultimately an exploration not of the sacred far-off but of the sacredness of places that are between-between the internal and external landscape, the self and others, and the self and the land. She finds that home is not a place where we arrive but a way of being in place, wherever that place may be. Along the way, Armbrecht explores the disconnections in our most intimate relationships, how they stem from the same disconnections that create our destruction of the land, and how one cannot be healed without attending to the other.
Thin Plates and Shells: Theory: Analysis, and Applications

Thin-Film Catalysts for Proton Exchange Membrane Water Electrolyzers and Unitized Regenerative Fuel Cells (Springer Theses)
by Peter KúšThis work revolves around the hydrogen economy and energy-storage electrochemical systems. More specifically, it investigates the possibility of using magnetron sputtering for deposition of efficient thin-film anode catalysts with low noble metal content for proton exchange membrane water electrolyzers (PEM-WEs) and unitized regenerative fuel cells (PEM-URFCs). The motivation for this research derives from the urgent need to minimize the price of such electrochemical devices should they enter the mass production. Numerous experiments were carried out, correlating the actual in-cell performance with the varying position of thin-film catalyst within the membrane electrode assembly, with the composition of high-surface support sublayer and with the chemical structure of the catalyst itself. The wide arsenal of analytical methods ranging from electrochemical impedance spectroscopy through electrochemical atomic force microscopy to photoelectron spectroscopy allowed a description of the complex phenomena behind different obtained efficiencies. Systematic optimizations led to the design of a novel PEM-WE anode thin-film iridium catalyst which performs similarly to the standard counterparts despite using just a fraction of their noble metal content. Moreover, the layer-by-layer approach allowed the design of a Pt/TiC/Ir bi-functional anode for PEM-URFC which is able to operate in both the fuel cell and electrolyzer regime and thus helps to cut the cost of the whole conversion system even further.
Thin-Film Organic Photonics: Molecular Layer Deposition and Applications (Optics and Photonics)
by Tetsuzo YoshimuraAmong the many atomic/molecular assembling techniques used to develop artificial materials, molecular layer deposition (MLD) continues to receive special attention as the next-generation growth technique for organic thin-film materials used in photonics and electronics. Thin-Film Organic Photonics: Molecular Layer Deposition and Applications describes how photonic/electronic properties of thin films can be improved through MLD, which enables precise control of atomic and molecular arrangements to construct a wire network that achieves "three-dimensional growth". MLD facilitates dot-by-dot—or molecule-by-molecule—growth of polymer and molecular wires, and that enhanced level of control creates numerous application possibilities. Explores the wide range of MLD applications in solar energy and optics, as well as proposed uses in biomedical photonics This book addresses the prospects for artificial materials with atomic/molecular-level tailored structures, especially those featuring MLD and conjugated polymers with multiple quantum dots (MQDs), or polymer MQDs. In particular, the author focuses on the application of artificial organic thin films to: Photonics/electronics, particularly in optical interconnects used in computersOptical switching and solar energy conversion systems Bio/ medical photonics, such as photodynamic therapy Organic photonic materials, devices, and integration processes With its clear and concise presentation, this book demonstrates exactly how MLD enables electron wavefunction control, thereby improving material performance and generating new photonic/electronic phenomena.

Thing Explainer
by Randall MunroeHave you ever tried to learn more about some incredible thing, only to be frustrated by incomprehensible jargon? Randall Munroe is here to help. In Thing Explainer, he uses line drawings and only the thousand (or, rather, "ten hundred") most common words to provide simple explanations for some of the most interesting stuff there is, including:food-heating radio boxes (microwaves)tall roads (bridges)computer buildings (datacenters)the shared space house (the International Space Station)the other worlds around the sun (the solar system)the big flat rocks we live on (tectonic plates)the pieces everything is made of (the periodic table)planes with turning wings (helicopters)boxes that make clothes smell better (washers and dryers)the bags of stuff inside you (cells) How do these things work? Where do they come from? What would life be like without them? And what would happen if we opened them up, heated them up, cooled them down, pointed them in a different direction, or pressed this button? In Thing Explainer, Munroe gives us the answers to these questions and so many more. Funny, interesting, and always understandable, this book is for anyone--age 5 to 105--who has ever wondered how things work, and why.
Thing Explainer: Complicated Stuff in Simple Words
by Randall MunroeFrom the No. 1 bestselling author of What If? - the man who created xkcd and explained the laws of science with cartoons - comes a series of brilliantly simple diagrams ('blueprints' if you want to be complicated about it) that show how important things work: from the nuclear bomb to the biro. It's good to know what the parts of a thing are called, but it's much more interesting to know what they do. Richard Feynman once said that if you can't explain something to a first-year student, you don't really get it. In Thing Explainer, Randall Munroe takes a quantum leap past this: he explains things using only drawings and a vocabulary of just our 1,000 (or the ten hundred) most common words.Many of the things we use every day - like our food-heating radio boxes ('microwaves'), our very tall roads ('bridges'), and our computer rooms ('datacentres') - are strange to us. So are the other worlds around our sun (the solar system), the big flat rocks we live on (tectonic plates), and even the stuff inside us (cells). Where do these things come from? How do they work? What do they look like if you open them up? And what would happen if we heated them up, cooled them down, pointed them in a different direction, or pressed this button?In Thing Explainer, Munroe gives us the answers to these questions and many, many more. Funny, interesting, and always understandable, this book is for anyone -- age 5 to 105 -- who has ever wondered how things work, and why.
Thing Knowledge: A Philosophy of Scientific Instruments
by Davis BairdDrawing on a wide range of case studies, Thing Knowledge argues that scientific instuments are more than mere tools for examining phenonmena, but rather bearers of knowledge.
Thing Knowledge: A Philosophy of Scientific Instruments
by Davis BairdWestern philosophers have traditionally concentrated on theory as the means for expressing knowledge about a variety of phenomena. This absorbing book challenges this fundamental notion by showing how objects themselves, specifically scientific instruments, can express knowledge. As he considers numerous intriguing examples, Davis Baird gives us the tools to "read" the material products of science and technology and to understand their place in culture. Making a provocative and original challenge to our conception of knowledge itself, Thing Knowledge demands that we take a new look at theories of science and technology, knowledge, progress, and change. Baird considers a wide range of instruments, including Faraday's first electric motor, eighteenth-century mechanical models of the solar system, the cyclotron, various instruments developed by analytical chemists between 1930 and 1960, spectrometers, and more.
Things Fall Together: A Guide to the New Materials Revolution
by Skylar TibbitsFrom the visionary founder of the Self-Assembly Lab at MIT, a manifesto for the dawning age of active materialsThings in life tend to fall apart. Cars break down. Buildings fall into disrepair. Personal items deteriorate. Yet today's researchers are exploiting newly understood properties of matter to program materials that physically sense, adapt, and fall together instead of apart. These materials open new directions for industrial innovation and challenge us to rethink the way we build and collaborate with our environment. Things Fall Together is a provocative guide to this emerging, often mind-bending reality, presenting a bold vision for harnessing the intelligence embedded in the material world.Drawing on his pioneering work on self-assembly and programmable material technologies, Skylar Tibbits lays out the core, frequently counterintuitive ideas and strategies that animate this new approach to design and innovation. From furniture that builds itself to shoes printed flat that jump into shape to islands that grow themselves, he describes how matter can compute and exhibit behaviors that we typically associate with biological organisms, and challenges our fundamental assumptions about what physical materials can do and how we can interact with them. Intelligent products today often rely on electronics, batteries, and complicated mechanisms. Tibbits offers a different approach, showing how we can design simple and elegant material intelligence that may one day animate and improve itself—and along the way help us build a more sustainable future.Compelling and beautifully designed, Things Fall Together provides an insider's perspective on the materials revolution that lies ahead, revealing the spectacular possibilities for designing active materials that can self-assemble, collaborate, and one day even evolve and design on their own.
