Book Description
This volume contains papers presented at the Second Symposium on Ordered Fluids and Liquid Crystals held at the 158th National Meeting of the American Chemical Society, New York, Sep tember, 1969. The Symposium was sponsored by the Division of Colloid and Surface Chemistry. The proceedings for the first symposium on this subject were published by the American Chemical Society in the Advances in Chemistry Series. In the preface to the volume for the first meet ing held four years ago, we noted that research on liquid crystals had gone through tremendous fluctuations, with peaks of activity around 1900 and again in the early 1930's. The present period of high activity which started about 1960 has continued to exhibit acceleration. The reason for the persistent growth in the field is due to the increasing recognition of the important role played by liquid crystals in both biological systems and in items of commerce as diverse as detergents and electronic components. Addi tionally, more powerful and sophisticated instrumentation is pro viding a basis for understanding the properties of the liquid crystalline state as weIl as yielding inc~s~ve tests for the theories of mesophase structure which are only now reaching astate of maturity.

Book Description
This is a book on the dissipative dynamics of ordered fluids, with a particular focus on liquid crystals. It covers a whole range of different theories, mainly concerned with nematic liquid crystals in both their chiral and nonchiral variants. The authors begin by giving a detailed account of the molecular origins of orientational order in fluids. They then go on to develop a general framework in which continuum theories for ordered fluids can be phrased. Within this unified setting, they cover both well-established classical theories and new ones with aspects that are not yet completely settled. The book treats a wide range of hydrodynamic theories for liquid crystals, from the original 1960s works by Ericksen and Leslie to new, fast-developing ideas of liquid crystal science. The final chapter is devoted to nematoacoustics and its applications. Old experiments on the propagation of ultrasound waves in nematic liquid crystals are interpreted and explained in the light of a new theory developed within the general theoretical infrastructure proposed in the body of the book. This book is intended both for graduate students and professional scholars in mathematics, physics, and engineering of advanced materials. It delivers a solid framework for liquid crystal hydrodynamics and shows the unifying concepts at the basis of the classical theories. It illustrates how these concepts can also be applied to a wide variety of modern topics. Andre M. Sonnet is in the Department of Mathematics and Statistics at the University of Strathclyde, Glasgow (Scotland) and Epifanio G. Virga is in the Department of Mathematics at the University of Pavia (Italy). They have a long history of working together in liquid crystal science and have contributed, in particular, to the theories of defects and biaxial nematics.

Book Description
This volume represents a collection of selected papers presented at a symposium of the same name sponsored by the Division of Colloid and Surface Chemistry held at the national Spring meeting of the American Chemical Society in Las Vegas, Nevada, March 29 - April 1, 1982. Also included are invited papers from a number of outstanding overseas liquid crystal scientists who were unable to attend the symposium. The attendance at the symposium itself and the number of papers contained herein is reflective of the high level of current interest in (and maturity of) the field of liquid crystal research. Included in this volume are papers mainly derived from the fields of chemistry and physics ranging in content from the design and synthesis of new meso genic materials to theoretical physical treatments of anisotropic liquids. One of the significant aspects of current liquid crystal research is the increasing col laboration between chemist and phys.icist. The overlap of these two areas has been growing over the last several years and many contri butions to this volume involve a molecular approach to the chemical physics of liquid crystalline materials.

Book Description
While it is responsible for today’s abundance of flat screens—on televisions, computers, and mobile devices—most of us have only heard of it in the ubiquitous acronym, LCD, with little thought as to exactly what it is: liquid crystal. In this book, Esther Leslie enlightens us, offering an accessible and fascinating look at—not a substance, not a technology—but a wholly different phase of matter. As she explains, liquid crystal is a curious material phase that organizes a substance’s molecules in a crystalline form yet allows them to move fluidly like water. Observed since the nineteenth century, this phase has been a deep curiosity to science and, in more recent times, the key to a new era of media technology. In between that time, as Leslie shows, it has figured in cultural forms from Romantic landscape painting to snow globes, from mountaineering to eco-disasters, and from touchscreen devices to DNA. Expertly written but accessible, Liquid Crystals recounts the unheralded but hugely significant emergence of this unique form of matter.

Book Description
This volume represents a collection of selected papers from a symposium of the Division of Colloid and Surface Chemistry held in Chicago during the national meeting of the American Chemical Society, August, 1973. The response was remarkable to this "By Invitation" symposium on Ordered Fluids and Liquid Crystals. The size alone expresses the growth of the field. The number of contributions assembled here, for example, is approximately twice that at each of the two previous American Chemical Society symposia on this subject. Contributions from eleven countries were presented and this volume contains more than this number of papers from abroad. The increased attention to liquid crystals has brought some interesting trends in the kinds of systems, the experimental methods, and the nature of the lahoratories involved. There has, for example, been an impressive increase in the number of academic studies on liquid crystals. The works herewith published also represent an im pressive variety of traditional and novel eXperimental techniques for the study of liquid crystals. These include rheology, infrared spec troscopy, dielectrics, ultrasonics, pulsed NMR, the Kerr effect, plus thermal and electrical conductivity.

Book Description
Practically every display technology in use today relies on the flat, energy-efficient construction made possible by liquid crystals. These displays provide visually-crisp, vibrantly-colored images that a short time ago were thought only possible in science fiction. Liquid crystals are known mainly for their use in display technologies, but they also provide many diverse and useful applications: adaptive optics, electro-optical devices, films, lasers, photovoltaics, privacy windows, skin cleansers and soaps, and thermometers. The striking images of liquid crystals changing color under polarized lighting conditions are even on display in many museums and art galleries--true examples of 'science meeting art'. Although liquid crystals provide us with visually stunning displays, fascinating applications, and are a rich and fruitful source of interdisciplinary research, their full potential may yet remain untapped.

Book Description
This new edition of the classic text incorporates the many advances in knowledge about liquid crystals that have taken place since its initial publication in 1974. Entirely new chapters describe the types and properties of liquid crystals in terms of both recently discovered phases and current insight into the nature of local order and isotropic-to-nematic transition. There is an extensive discussion of the symmetrical, macroscopic, dynamic, and defective properties of smectics and columnar phases, with emphasis on order-of-magnitude considerations, all illustrated with numerous descriptions of experimental arrangements. The final chapter is devoted to phase transitions in smectics, including the celebrated analogy between smectic A and superconductors. This new version's topicality and breadth of coverage will ensure that it remains an indispensable guide for researchers and graduate students in mechanics and engineering, and in chemical, solid state, and statistical physics.
