Book Description
This book reviews comprehensively the technological, scientific, artistic and medical applications of liquid crystals. It starts with the basics of liquid crystals and covers electro-optical, thermo-optical, colour, polymeric, lyotropic, and scientific applications of liquid crystalline materials. It discusses the fabrication and operational principles of a full range of liquid crystal displays including dynamic scattering, twisted nematic, supertwisted nematic, dichroic, smectic A, ferroelectric, polymer dispersed, light valve, active matrix, etc., in detail. It also covers the emerging applications of liquid crystals such as optical computing, nonlinear optics, decorative and visual arts. Classification, theory, chemical structure, physical properties and surface alignment of liquid crystals have detailed chapters to facilitate the basic understanding of the science behind LCDs and other uses of liquid crystals. The chapters, liquid crystal polymers and lyotropic liquid crystals, give deep insight into these areas. The potential uses and applications are also described in detail.

Book Description
Over the past ten years liquid crystals have attracted much interest and considerable progress has been made with respect to our knowledge in this field. The recent development was initiated mainly by the work of J. L. Fergason and G. H. Heilmeier, who pointed out the importance of liquid crystals for thermographic and electro optic applications. The first part of this book is a brief introduction to the physics of liquid crystals. The structures and properties of the three basic types of liquid crystals are discussed. A special paragraph is devoted to electric-field effects, which are important in display applications. The chapter on Scientific Applications gives an insight into the potential applications of liquid crystals in fundamental research, with special emphasis on explaining the principles involved. Two groups of potential applications are discussed in detail: 1. the use of liquid crystals as anisotropic solvent for the determination of molecular properties by means of spectroscopy, and 2. their use in analytical chemistry, particularly in gas chromatography. The reverse process involves the use of the dissolved molecules as microscopic probes in the investigation of the dynamical molecular structure of anisotropic fluid systems (e.g. biological membranes). This extremely important technique is also described.

Book Description
Liquid crystal displays were discovered in the 1960s, and today we continue to enjoy the benefits of that fundamental discovery and its translation into a wide variety of products. Like liquid crystals, polymers are unusual materials, and have similarly enjoyed a great deal of research attention because of their vast applications and uses and complex fundamental properties. The combination of liquid crystal and polymer properties produces a broad array of new effects—spanning from densely crosslinked, rigid polymer networks to weakly crosslinked elastomers—that are not simply manifestations of either native liquid crystals or polymers alone. Cross-Linked Liquid Crystalline Systems brings together liquid crystal and polymer systems and their variations. The field, much like traditional liquid crystals, is one of an interdisciplinary nature with a broad spectrum, from the very fundamental questions of nature to a myriad of practical uses. There seems to be no shortage of unusual properties and far-reaching applications in densely crossed-linked liquid crystal systems and liquid crystal elastomers. These systems provide a rich new avenue for both fundamental and applied research and continue to fascinate scientists and engineers. Specifically, this book covers: Cross-linked networks created from reactive mesogen materials Manipulation of liquid crystalline by external constraints Advances in liquid crystal display screen technology Physical and electromagnetic properties of elastomers and magnetic gels Computer simulations and theory of liquid crystal polymeric networks and elastomers Side-on nematic liquid-crystalline elastomers for artificial muscle applications Liquid crystal display technology has driven much of the fundamental research in crosslinked liquid crystalline systems. The systems’ ability to enforce three-dimensional structure in the molecular order and capture it created a number of compelling application possibilities because it provided necessary control of the molecular order. This book advances the understanding of basic science behind these systems, accelerates some of the proposed applications to the marketplace, and hopes to inspire generations of scientists to think broadly about these exciting and useful materials.

Book Description
In the past few years, bent-core liquid crystals have created immense interest in the scientific community because they show several new liquid crystalline phases along with some known phases of calamitic liquid crystals. Concomitantly efforts are made to synthesize liquid crystals with unconventional shapes like, V, W, T etc. Many physical properties of these new liquid crystals are not yet understood. This book is an attempt to understand the structure-property correlation of some unconventional nematic liquid crystals. We have presented some introduction and experimental techniques to measure various physical properties of those unconventional liquid crystals in the first two chapters. In the subsequent chapters we discuss physical properties of liquid crystal mixture of rod-like and bent-core molecules, pure bent-core molecules, hockey stick shaped (asymmetric bent-core) and T-shaped molecules. Finally we discuss flexoelectric properties in the last chapter.

Book Description
This is a new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals, first published in 1977. The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications. This book presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals - the three classical types, nematic, cholesteric and smectic, and the newly discovered discotic type. Included is a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behaviour under external fields. The basic principles underlying the major applications of liquid crystals in display technology and in thermography are also discussed. This book will be of great value to advanced students and researchers in condensed matter physics, chemical physics, materials science and technology with an interest in the physics, chemistry and applications of liquid crystals.

Book Description
Liquid Crystals - Self-Organized Soft Functional Materials for Advanced Applications is focused on both theoretical models and experimental results, pointing out the chemical and physical properties (thermodynamics, electro-optic switching behavior, and non-linear optic phenomena) of liquid crystals used in a wide range of devices. In this respect, the chapters cover the following topics: chemical structure and phase transitions in bent-core liquid crystals, phase and structural behavior of liquid crystals used to align carbon nanotubes, molecular alignment, and photorefractive effect in the ferroelectric phase, which has the potential to be used as transistors, for image storage, and in optical signal processing. It is expected that the book will be of interest to researchers in academia and industries, as well as advanced students.

Book Description
This text relies on only introductory level physics and chemistry as the foundation for understanding liquid crystal science. Liquid crystals combine the material properties of solids with the flow properties of fluids. As such they have provided the foundation for a revolution in low- power, flat-panel display technology LCDs. In this book, the essential elements of liquid crystal science are introduced and explained from the perspectives of both the chemist and the physicist.; The text begins with an historical account of the discovery of liquid crystals and continues with a description of how different phases are generated and how different molecular architectures affect liquid crystalline properties. The rest of the book is concerned with understanding and explaining the properties of the various types of liquid crystals, and in the final part of the book, the technology of LCDs is discussed and illustrated.
