Описание: An intrinsic brittleness of oxide cuprates, the layered anisotropic structure and the supershort coherence length are the main features of HTS defining their properties. Taking into account these features, the researching of HTS microstructure and properties is presented, and also the possibilities of optimization of the preparation techniques and superconducting compositions are considered. The link "composition-technique-experiment-theory-model" investigated in the book, assuming considerable HTSC defectiveness and structure heterogeneity, forms whole picture of modern representations on the microstructure, strength and connected with them the structure-sensitive properties of the materials considered. Especial attention is devoted in the book to the Bi-Sr-Ca-Cu-O and Y-Ba-Cu-O families, that today are most perspective for applications. The book includes great number of illustrations and references. The monograph is addressed to students, post-graduate students and specialists, taking part in the development, preparation and researching new materials.
Описание: Over recent years the understanding of grain boundaries, interphase boundaries and free surfaces has advanced greatly, leading to a clear recognition that these discontinuities make a significant contribution to the physical and mechanical properties of materials from multiphametals and alloys to electronic materials. Grain Boundaries -Their Microstructure and Chemistry discusses the interrelationship between microstructure and chemistry of the grain boundary, with particular emphasis on the influence of the environment (air, liquid and liquid metal) and composition (bulk and impurity). This highly practical volume presents a brief background to interphase and grain boundaries, before considering in detail grain boundary composition and composition changes, and how grain boundary composition affects material properties. Very recent advances in techniques such as electron energy loss spectroscopy, high-resolution transmission electron microscopy and atom probe, and the facinating new insights into grain boundary, microstructure that they have revealed, are also discussed. Grain Boundaries - Their Microstructure and Chemistry is an indispensable text for design and safety engineers in many industries, including power and aerospace, as well as for materials scientists and engineers in academia and research institutes.
Описание: "Integrated Optics, Microstructures, and Sensors" establishes a common ground between researchers in integrated optics and microstructures by providing a
comprehensive coverage of the basics of both fields. It is the only book that incorporates these two independently developed fields to create better, more sensitive and simpler sensors.
This book is useful to researchers seeking to develop ultra-sensitive sensors for use in harsh and corrosive environments, and scientists - both industrial and academic - interested in
novel sensing schemes.
Описание: The main theme of this book is micromagnetism and microstructure as well as the analysis of the relations between characteristic properties of the hysteresis loop and microstructure. Also presented is an analysis of the role of microstructure in the fundamental magnetic properties (for example magnetorestriction or critical behaviour) of crystalline and amorphous alloys. The authors apply the theory of micromagnetism to all aspects of advanced magnetic materials including domain patterns and magnetization processes under the influence of defect structures. Coverage includes modern developments in computational micromagnetism and its application to spin structures of small particles and platelets. It will be of interest to researchers and graduate students in condensed matter, physics, electrical engineering and materials science, as well as to industrial researchers working in the electrotechnical and recording industry.
Описание: Interesting and new specific results of current theoretical and experimental work in various fields at the frontier of particle scattering and X-ray diffraction are reviewed in this volume. Special emphasis is placed on the study of the microstructure of solids, crystals and liquids, both classically and quantum mechanically. This gives the reader essential insights into the dynamics and properties of these states of matter. The authors address students interested in the physics of quantum solids, crystallography and material science as well as physical chemistry and computational physics.
Описание: Diffraction Analysis of the Microstructure of Materials provides an overview of diffraction methods applied to the analysis of the microstructure of materials. Since crystallite size and the presence of lattice defects have a decisive influence on the properties of many engineering materials, information about this microstructure is of vital importance in developing and assessing materials for practical applications. The most powerful and usually non-destructive evaluation techniques available are X-ray and neutron diffraction. The book details, among other things, diffraction-line broadening methods for determining crystallite size and atomic-scale strain due, e.g. to dislocations, and methods for the analysis of residual (macroscale) stress. The book assumes only a basic knowledge of solid-state physics and supplies readers sufficient information to apply the methods themselves.
Описание: Phase transformations in solids typically lead to surprising mechanical behaviour with far reaching technological applications. The mathematical modeling of these transformations in the late 80s initiated a new field of research in applied mathematics, often referred to as mathematical materials science, with deep connections to the calculus of variations and the theory of partial differential equations. This volume gives a brief introduction to the essential physical background, in particular for shape memory alloys and a special class of polymers (nematic elastomers). Then the underlying mathematical concepts are presented with a strong emphasis on the importance of quasiconvex hulls of sets for experiments, analytical approaches, and numerical simulations.
Описание: Combining the positive characteristics of microfluidics and optics, microstructured optical fibres (MOFs) have revolutionized the field of optoelectronics. Tailored guiding, diffractive structures and photonic band-gap effects are used to produce fibres with highly specialised, complex structures, facilitating the development of novel kinds of optical fibre sensors and actuators. Part One outlines the key materials and fabrication techniques used for microstructured optical fibres. Microfluidics and heat flows, MOF-based metamaterials, novel and liquid crystal infiltrated photonic crystal fibre (PCF) designs, MOFs filled with carbon nanotubes and melting of functional inorganic glasses inside PCFs are all reviewed. Part Two then goes on to investigate sensing and optofluidic applications, with the use of MOFs in structural sensing, sensing units and mechanical sensing explored in detail. PCF’s for switching applications are then discussed before the book concludes by reviewing MOFs for specific nucleic acid detection and resonant bio- and chemical sensing.

Описание: This book throws some light on poorly understood aspects of the motion of magnetization in magnetic solids, particularly the effects of dissipative mechanisms. Aside from its practical aspects (such as magnetic recording), it addresses readers interested in the basic physics of nonlinear phenomena.
Описание: Characterization of Microstructures by Analytical Electron Microscopy (AEM) describes the basic concepts and operative techniques of AEM.
