Micro & Nano-Engineering of Fuel Cells - - Bog - Taylor & Francis Ltd - Plusbog.dk

Micro & Nano-Engineering of Fuel Cells - - Bog - Taylor & Francis Ltd - Plusbog.dk

Fuel cells are clean and efficient energy conversion devices expected to be the next generation power source. During more than 17 decades of research and development, various types of fuel cells have been developed with a view to meet the different energy demands and application requirements. Scientists have devoted a great deal of time and effort to the development and commercialization of fuel cells important for our daily lives. However, abundant issues, ranging from mechanistic study to system integration, still need to be figured out before massive applications can be used. Miniaturization is one of the main bottlenecks for the advancement and further development of fuel cells. Thus, research on miniaturization of fuel cells as well as understanding the micro and nano structural effect on fuel cell performance are necessary and of great interest to solve the challenges ahead. In this book, internationally acclaimed experts illustrate how micro & nano engineering technology can be applied as a way of removing the restrictions presently faced by fuel cells both technically and theoretically. Through the twelve well designed chapters, major issues related to the miniaturization of different types of fuel cells are addressed. Theory focusing on micro and nano scale mechanics are outlined to better optimize the performance of fuel cells from laboratory scale to industrial scale. This book will be a good reference to those scientists and researchers interested in developing fuel cells through micro and nano scale engineering.

Micro-trauma - Margaret Crastnopol - Bog - Taylor & Francis Ltd - Plusbog.dk

Micro-trauma: A psychoanalytic understanding of cumulative psychic injury explores the "micro-traumatic" or small, subtle psychic hurts that build up to undermine a person’s sense of self-worth, skewing his or her character and compromising his or her relatedness to others. These injuries amount to what has been previously called "cumulative" or "relational trauma." Until now, psychoanalysis has explained such negative influences in broad strokes, using general concepts like psychosexual urges, narcissistic needs, and separation-individuation aims, among others. Taking a fresh approach, Margaret Crastnopol identifies certain specific patterns of injurious relating that cause damage in predictable ways; she shows how these destructive processes can be identified, stopped in their tracks, and replaced by a healthier way of functioning. Seven different types of micro-trauma, all largely hidden in plain sight, are described in detail, and many others are discussed more briefly. Three of these micro-traumas—"psychic airbrushing and excessive niceness," "uneasy intimacy," and "connoisseurship gone awry"—have a predominantly positive emotional tone, while the other four—"unkind cutting back," "unbridled indignation," "chronic entrenchment," and "little murders"—have a distinctly negative one. Margaret Crastnopol shows how these toxic processes may take place within a dyadic relationship, a family group, or a social clique, causing collateral psychic damage all around as a consequence. Using illustrations drawn from psychoanalytic treatment, literary fiction, and everyday life, Micro-trauma : A psychoanalytic understanding of cumulative psychic injury outlines how each micro-traumatic pattern develops and manifests itself, and how it wreaks its damage. The book shows how an awareness of these patterns can give us the therapeutic leverage needed to reshape them for the good. This publication will be an invaluable resource for psychoanalysts, psychologists, psychiatrists, mental health counselors, social workers, marriage and family therapists, and for trainees and graduate students in these fields and related disciplines. Margaret Crastnopol (Peggy), Ph.D. is a faculty member of the Seattle Psychoanalytic Society and Institute, and a Supervisor of Psychotherapy at the William Alanson White Institute of Psychiatry, Psychoanalysis & Psychology. She is also a Training and Supervising Analyst at the Institute of Contemporary Psychoanalysis, Los Angeles. She writes and teaches nationally and internationally about the analyst''s and patient''s subjectivity; the vicissitudes of love, lust, and attachment drives; and varieties of micro-trauma. She is in private practice for the treatment of individuals and couples in Seattle, WA.

Passive Micro-Optical Alignment Methods - - Bog - Taylor & Francis Ltd - Plusbog.dk

Passive Micro-Optical Alignment Methods - - Bog - Taylor & Francis Ltd - Plusbog.dk

The most expensive phase in the manufacture of micro-optical components and fiber optics is also one of the most performance-critical: optical alignment of the components. The increasing degree of miniaturization makes this an especially challenging task. Active alignment methods result in higher costs and awkward processes, and for some applications, they simply are not possible. Passive Micro-Optical Alignment Methods introduces the passive alignment methods that are currently available and illustrates them with many examples, references, and critiques. The first book dedicated to passive alignment, it begins with an overview of the current activities, requirements, and general results of passive optical alignments, followed by three sections of in-depth analysis. The first of these discusses mechanical passive alignment, highlighting silicon waferboard, solder, and "Jitney" technologies as well as application of mechanical alignment to 3D free-space interconnects. The next section describes the various visual alignment techniques applied to Planar Lightwave Circuits (PLCs) and low-cost plastic and surface mount packaging. The final section details various utilities that aid passive alignment and their resulting tradeoffs and demonstrates Monte Carlo analysis to evaluate the potential of a given method. Passive Micro-Optical Alignment Methods provides the tools necessary to meet the challenge of precision and low-cost alignment for applications that require micron or sub-micron tolerance.

Micro- and Nanoscale Phenomena in Tribology - - Bog - Taylor & Francis Ltd - Plusbog.dk

Micro- and Nanoscale Phenomena in Tribology - - Bog - Taylor & Francis Ltd - Plusbog.dk

Drawn from presentations at a recent National Science Foundation Summer Institute on Nanomechanics, Nanomaterials, and Micro/Nanomanufacturing, Micro- and Nanoscale Phenomena in Tribology explores the convergence of the multiple science and engineering disciplines involved in tribology and the connection from the macro to nano world. Written by specialists from computation, materials science, mechanical engineering, surface physics, and chemistry, each chapter provides up-to-date coverage of both basic and advanced topics and includes extensive references for further study. After discussing the evolution of tribology in the micro and nano world, the book describes contact conditions spanning between macroscale and nanoscale contacts. It presents an overview of fundamental continuum treatments of interfacial contact and lubrication under a wide range of conditions, including novel advances in contact simulation. It also gives a thorough account of the nature of surface energies and forces in nanostructures as well as adhesion in dry and wet environments. The book then explains how to perform friction measurements at the nanoscale and interpret friction data before demonstrating how micro- and nanotextured surfaces affect adhesion, friction, and wetting. The final chapters emphasize the importance of surface chemistry and molecular dynamics simulation in tribology. With numerous examples and figures throughout, this volume presents a thorough account of important advancements in tribology that offer insight into micro- and nanoscale phenomena. By enabling a better understanding of fundamental micro- and nanoscale interactions, the book helps readers effectively design and fabricate durable tribological components for various engineering and biological systems.
