Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Download or read book Wood Adhesives written by Antonio Pizzi and published by CRC Press. This book was released on 2011-01-07 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.

Book Synopsis Diamond Based Composites by : Mark A. Prelas
Download or read book Diamond Based Composites written by Mark A. Prelas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond-based composites, with their advantages of hardness, high Young's modulus and the like, have demonstrated new and unusual features, such as stability to high temperatures and pressure shocks and a large internal surface that can be controlled to offer customised electrical, magnetic and optical properties, leading to efficient filters, absorbents, sensors and other tools for environmental control and monitoring. The current book covers the synthesis of materials, their characterization and properties, trends in high pressure and high temperature technologies, low pressure technologies, basic principles of DBC material science, and future developments in electronics, optics, industrial tools and components, biotechnology, and medicine. Wide band-gap materials are considered, ranging from molecular clusters, nanophase materials, growth, processing and synthesis. The processing of composite based materials can be classified into six basic methods: in situ growth, high pressure/high temperature catalytic conversion; mix and sinter (c-BN plus metal-ceramic polymer mix); direct sintering; direct polymorphic conversion; shock detonation; and SHS sintering.

Book Synopsis La diffraction des rayons X par les cristaux liquides by : Anne-Marie Levelut
Download or read book La diffraction des rayons X par les cristaux liquides written by Anne-Marie Levelut and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les cristaux liquides sont des substances qui présentent un ou plusieurs états de la matière intermédiaires entre le solide cristallin et le liquide usuel. Ces états cristaux-liquides se caractérisent par les organisations spécifiques à l'échelle microscopique de leurs constituants : molécules, polymères, nanoparticules... Les cristaux liquides se retrouvent fréquemment dans la vie courante, par exemple dans les dispositifs d'affichage, détergents, matériaux composites, structures biologiques. Ils font l'objet d'une recherche active dont l'un des buts est de déterminer leur structure pour les identifier. Ces études structurales sont le plus souvent effectuées par diffusion de rayonnements, en particulier de rayons X. C'est cette diffusion de rayons X qui fait l'objet de cet ouvrage, qui comporte deux tomes. Le premier tome présentait une introduction aux notions fondamentales de diffusion de rayonnement et décrivait en détail l'état cristal-liquide le plus courant, appelé "nématique". Ce second tome est consacré à des états cristaux-liquides plus ordonnés dans lesquels les constituants possèdent, outre l'ordre d'orientation, un ordre de position. Suivant que cet ordre de position se développe dans une, deux ou trois dimensions de l'espace, ces états cristaux-liquides sont respectivement appelés "smectiques", "colonnaires" ou "réseaux tridimensionnels de défauts". Une première partie (la troisième de l'ouvrage) traite des états smectiques, des plus organisés, très proches des cristaux usuels, aux plus désordonnés, appelés smectiques liquides colonnaires. La dernière partie expose l'étude structurale de réseaux tridimensionnels de défauts : cristaux d'interfaces et réseaux spécifiques des molécules chirales. Enfin, une annexe récapitule l'identification par diffusion de rayons X des nombreuses structures des cristaux liquides et une autre en propose une classification uniquement basée sur les propriétés de symétrie.

Available in PDF, EPUB and Kindle. Book excerpt: X-ray diffraction crystallography for powder samples is a well-established and widely used method. It is applied to materials characterization to reveal the atomic scale structure of various substances in a variety of states. The book deals with fundamental properties of X-rays, geometry analysis of crystals, X-ray scattering and diffraction in polycrystalline samples and its application to the determination of the crystal structure. The reciprocal lattice and integrated diffraction intensity from crystals and symmetry analysis of crystals are explained. To learn the method of X-ray diffraction crystallography well and to be able to cope with the given subject, a certain number of exercises is presented in the book to calculate specific values for typical examples. This is particularly important for beginners in X-ray diffraction crystallography. One aim of this book is to offer guidance to solving the problems of 90 typical substances. For further convenience, 100 supplementary exercises are also provided with solutions. Some essential points with basic equations are summarized in each chapter, together with some relevant physical constants and the atomic scattering factors of the elements.
