Micromachined Mixed-Potential-Type YSZ-Based Sensors for Nitrogen Dioxide Monitoring in Automobile Exhaust (Springer Theses)
by Rui YouThis book presents original methods to facilitate the development of micro-mixed-potential-type nitrogen dioxide sensors, especially in the following aspects: (i) improvement of sensing performance of electrodes; (ii) enhancement of chemical activity of reaction interface; (iii) development of advanced flexible low-power-consumption mixed-potential-type YSZ-based nitrogen dioxide sensors. Miniaturized sensors have steadily emerged into the commercial marketplace as competitive alternatives for monitoring and controlling the pollution gas in automobile industry. Despite the great potential, the real-world applications for most conventional micro-nitrogen dioxide sensors are still limited due to insufficient sensitivity, unacceptable cost, and the lack of robustness under harsh environmental disturbances. To address the issue, micro-nitrogen dioxide sensors based on mixed potential solid electrolyte is an ongoing area of great academic and technological interest. This book is expectedto be a guide for researchers on the way forward to chase future horizons in the fields of instrumentation, electrochemistry and micro/nano-electronics.

Micromachining with Nanostructured Cutting Tools
by Mark J. JacksonStress-reducing defects and subsequent microcracks are a central focus during micromachining processes. After establishing the central process of micromachining Micromachining with Nanostructured Cutting Tools explains the underlying theories that describe chip formation and applies elementary cutting theory to machining at the microscale. Divided into three parts, the second half of Micromachining with Nanostructured Cutting Tools develops on this introduction; explaining how frictional interactions between uncoated and micro tools coated with nanostructered coatings can be characterized by using the elementary micromachining theories that were initially developed for machining at the macroscale. Shaw's methods for calculating temperatures at the interaction zone and Merchant's methods for calculating mechanical interactions are well described and justified for machining steel in both the dry and wet states. Finally, the further development and use of micro tools coated with thin-film nanostructured diamonds are shown. Micromachining with Nanostructured Cutting Tools is a resource for engineers and scientists working in this new field of micro and nanotechnology. The explanations of how to characterize, apply and adapt traditional approaches of understanding the mechanics of practical machining to the machining of microproducts using nanostructured tools provides a reliable reference for researchers and practitioners alike.
Micromagnetics and Recording Materials
by Dan Wei"Micromagnetics and Recording Materials" is a book trying to give a systematic theory of computational applied magnetism, based on Maxwell equations of fields and Landau-Lifshitz equations of magnetic moments. The focused magnetic materials are magnetic recording materials utilized in computer hard disk drives. Traditionally, "Micromagnetics" includes the areas of "magnetization curve theory", "domain theory" and "read and write process analyses in recording systems". As Springer Briefs, this book includes the first two areas of micromagnetics. M-H loops of hard magnetic thin film media, soft magnetic layers and Tunneling MagnetoResistive spin valves are solved based on the microstructures of thin films. Static domain structures and dynamic switching processes are analyzed in the arbitrary-shaped magnetic devices such as write head pole tips and magnetic force microscope tips. The book is intended for researchers who are interested in applied magnetism and magnetic recording in all disciples of physical science. Prof. Dan Wei works at Tsinghua University, China.

Micromechanics Modelling of Ductile Fracture
by Zengtao Chen Cliff ButcherThis book summarizes research advances in micromechanics modeling of ductile fractures made in the past two decades. The ultimate goal of this book is to reach manufacturing frontline designers and materials engineers by providing a user-oriented, theoretical background of micromechanics modeling. Accordingly, the book is organized in a unique way, first presenting a vigorous damage percolation model developed by the authors over the last ten years. This model overcomes almost all difficulties of the existing models and can be used to completely accommodate ductile damage developments within a single-measure microstructure frame. Related void damage criteria including nucleation, growth and coalescence are then discussed in detail: how they are improved, when and where they are used in the model, and how the model performs in comparison with the existing models. Sample forming simulations are provided to illustrate the model's performance.
Micromechanics of Ceramic-Matrix Composites at Elevated Temperatures (Advanced Ceramics and Composites #6)
by Longbiao LiCeramic-matrix composites (CMCs) possess high specific strength and modulus at elevated temperature, and have already been applied in hot-section components in aero-engines. To ensure the operation reliability and safety of CMCs components, it is necessary to understand the micro damage mechanisms and internal damage state in the composites. This book focuses on the micromechanics of CMCs at elevated temperatures, including, the stress-strain behavior, proportional limit stress, residual strength, mechanical hysteresis, interface damage, strain response, and lifetime of CMCs at elevated temperatures. This book can help the material scientists and engineering designers to better understand and master the micromechanics of CMCs at elevated temperatures.
Micromechanics of Composite Materials
by George DvorakThis book presents a broad exposition of analytical and numerical methods for modeling composite materials, laminates, polycrystals and other heterogeneous solids, with emphasis on connections between material properties and responses on several length scales, ranging from the nano and microscales to the macroscale. Many new results and methods developed by the author are incorporated into the rich fabric of the subject, which has developed from the work of many researchers over the last 50 years. Among the new results, the book offers an extensive analysis of internal and interface stresses caused by eigenstrains, such as thermal, transformation and inelastic strains in the constituents, which often exceed those caused by mechanical loads, and of inelastic behavior of metal matrix composites. Fiber prestress in laminates, and modeling of functionally graded materials are also analyzed. Furthermore, this book outlines several key subjects on modeling the properties of composites reinforced by particles of various shapes, aligned fibers, symmetric laminated plates and metal matrix composites. This volume is intended for advanced undergraduate and graduate students, researchers and engineers interested and involved in analysis and design of composite structures.
Micromechanics of Fiber-Reinforced Laminae (SpringerBriefs in Applied Sciences and Technology)
by Andreas ÖchsnerThis book provides an introduction to the micromechanics of fiber-reinforced laminae, which deals with the prediction of the macroscopic mechanical lamina properties based on the mechanical properties of the constituents, i.e., fibers and matrix. Composite materials, especially fiber-reinforced composites, are gaining increasing importance since they can overcome the limits of many structures based on classical metals. Particularly, the combination of a matrix with fibers provides far better properties than the components alone. Despite their importance, many engineering degree programs do not treat the mechanical behavior of this class of advanced structured materials in detail, at least on the Bachelor degree level. Thus, some engineers are not able to thoroughly apply and introduce these modern engineering materials in their design process. The focus is on unidirectional lamina which can be described based on orthotropic constitutive equations. Three classical approaches to predict the elastic properties, i.e., the mechanics of materials approach, the elasticity solutions with contiguity after Tsai, and the Halpin–Tsai relationships, are presented. The quality of each prediction is benchmarked based on two different sets of experimental values. The book concludes with optimized representations, which were obtained based on the least square approach for the used experimental data sets.
Micromechanics of Fracture and Damage
by Djimedo Kondo Luc DormieuxThis book deals with the mechanics and physics of fractures at various scales. Based on advanced continuum mechanics of heterogeneous media, it develops a rigorous mathematical framework for single macrocrack problems as well as for the effective properties of microcracked materials. In both cases, two geometrical models of cracks are examined and discussed: the idealized representation of the crack as two parallel faces (the Griffith crack model), and the representation of a crack as a flat elliptic or ellipsoidal cavity (the Eshelby inhomogeneity problem). The book is composed of two parts: - The first part deals with solutions to 2D and 3D problems involving a single crack in linear elasticity. Elementary solutions of cracks problems in the different modes are fully worked. Various mathematical techniques are presented, including Neuber-Papkovitch displacement potentials, complex analysis with conformal mapping and Eshelby-based solutions. - The second part is devoted to continuum micromechanics approaches of microcracked materials in relation to methods and results presented in the first part. Various estimates and bounds of the effective elastic properties are presented. They are considered for the formulation and application of continuum micromechanics-based damage models.
Micromechanics of Materials, with Applications (Solid Mechanics and Its Applications #249)
by Igor Sevostianov Mark KachanovThis book on micromechanics explores both traditional aspects and the advances made in the last 10–15 years. The viewpoint it assumes is that the rapidly developing field of micromechanics, apart from being of fundamental scientific importance, is motivated by materials science applications. The introductory chapter provides the necessary background together with some less traditional material, examining e.g. approximate elastic symmetries, Rice’s technique of internal variables and multipole expansions. The remainder of the book is divided into the following parts: (A) classic results, which consist of Rift Valley Energy (RVE), Hill’s results, Eshelby’s results for ellipsoidal inhomogeneities, and approximate schemes for the effective properties; (B) results aimed at overcoming these limitations, such as volumes smaller than RVE, quantitative characterization of “irregular” microstructures, non-ellipsoidal inhomogeneities, and cross-property connections; (C) local fields and effects of interactions on them; and lastly (D) – the largest section – which explores applications to eight classes of materials that illustrate how to apply the micromechanics methodology to specific materials.
Micromechanisms of Friction and Wear
by Leonid Pinchuk Dmitrij Lyubimov Kirill DolgopolovThe modern vision of the micromechanism of friction and wear is explored, from the examination of ideal and real crystal structure and adhesion properties to the dynamics of solid frictional interaction. The fundamental quantum-mechanical and relativity principles of particle interaction are considered as basis of friction micro-process examination. The changes in solid structure originated from the influence of different kinds of force fields are considered. The principal possibility of relativity effect manifestation by friction is explained. The critical state of friction - triboplasma - was studied. Structural peculiarities of triboplasma, the kinetics of its transformation during frictional interaction as well as the influence of plasma and postplasma processes on tribojunction friction characteristics and complex formation by friction were examined. The book addresses to tribology researchers.

Micronutrients in Health and Disease, Second Edition
by Kedar PrasadIncreased oxidative stress due to the production of excessive amounts of free radicals along with the effects of chronic inflammation plays a major role in the initiation and progression of most chronic diseases. In addition, increased release of glutamate plays a central role in the pathogenesis of various disorders. <p><p>This second edition of Micronutrients in Health and Disease proposes a novel concept that in order to simultaneously and optimally reduce oxidative stress, chronic inflammation, and glutamate, it is essential to increase levels of antioxidant enzymes as well as levels of dietary and endogenous antioxidant compounds at the same time. This is accomplished by activating the Nrf2 pathways and by increasing the levels of antioxidant compounds and B-vitamins through supplementation. This book proposes a mixture of micronutrients that achieves this above goal. The mixture of micronutrients together with modification in diet and lifestyle may reduce the risk of chronic diseases and in combination with standard care, may improve the management of these diseases. <p><p>KEY FEATURES <li>Provides evidence in support of the idea that increased oxidative stress, chronic inflammation, and glutamate are involved in the pathogenesis of chronic diseases. <li>Contains three new chapters on Huntington’s disease, Autism spectra, and Prion disease. <li>Discusses the role of microRNAs in the pathogenesis of chronic diseases. <li>Presents information on regulation of the expression of microRNAs by reactive oxygen species and antioxidants. <p><p>Micronutrients in Health and Disease, Second Edition serves as a valuable resource for those seeking to promote healthy aging and prevent and improved management of chronic diseases.
Microoptics and Nanooptics Fabrication
by Shanalyn A. KemmeThe deep interconnection between micro/nanooptical components and related fabrication technologies—and the constant changes in this ever-evolving field—means that successful design depends on the engineer’s ability to accommodate cutting-edge theoretical developments in fabrication techniques and experimental realization.Documenting the state of the art in fabrication processes, Microoptics and Nanooptics Fabrication provides an up-to-date synopsis of recent breakthroughs in micro- and nanooptics that improve key developmental processes. This text elucidates the precise and miniaturized scale of today’s fabrication methods and their importance in creating new optical components to access the spectrum of physical optics. It details successful fabrication techniques and their direct effect on the intended performance of micro- and nanooptical components. The contributors explore the constraints related to material selection, component lateral extent, minimum feature size, and other issues that cause fabrication techniques to lag behind corresponding theory in the development process. Written with the professional optical engineer in mind, this book omits the already well-published broader processing fundamentals. Instead it focuses on key tricks of the trade helpful in reformulating processes to achieve necessary optical targets, improve process fidelity, and reduce production costs. The contributing authors represent the vanguard in micro-optical fabrication. The result of their combined efforts, this searing analysis of emerging fabrication technologies will continue to fuel the expansion of optics components, from the microwave to the infrared through the visible regime.
