Bent-Shaped Liquid Crystals by Hideo Takezoe,Alexey Eremin Pdf

Bent-Shaped Liquid Crystals: Structures and Physical Properties provides insight into the latest developments in the research on liquid crystals formed by bent-shaped mesogens. After a historical introduction, the expert authors discuss different kinds of mesophase structures formed by bent-shaped molecules. This book devotes the majority of its pages to physical properties such as polar switching, optics and non-linear optics, and behavior in restricted geometries. However, as chemistry is often highly relevant to the emergence of new phases, particularly with reflection symmetry breaking, it also involves a broad spectrum of interesting chemistry viewpoints.

Unconventional Nematic Liquid Crystals by Paladugu Sathyanarayana,Surajit Dhara Pdf

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.

Biaxial Nematic Liquid Crystals by Geoffrey R. Luckhurst,Timothy J. Sluckin Pdf

In the nematic liquid crystal phase, rod-shaped molecules move randomly but remain essentially parallel to one another. Biaxial nematics, which were first predicted in 1970 by Marvin Freiser, have their molecules differentially oriented along two axes. They have the potential to create displays with fast switching times and may have applications in thin-film displays and other liquid crystal technologies. This book is the first to be concerned solely with biaxial nematic liquid crystals, both lyotropic and thermotropic, formed by low molar mass as well as polymeric systems. It opens with a general introduction to the biaxial nematic phase and covers: • Order parameters and distribution functions • Molecular field theory • Theories for hard biaxial particles • Computer simulation of biaxial nematics • Alignment of the phase • Display applications • Characterisation and identification • Lyotropic, thermotropic and colloidal systems together with material design With a consistent, coherent and pedagogical approach, this book brings together theory, simulations and experimental studies; it includes contributions from some of the leading figures in the field. It is relevant to students and researchers as well as to industry professionals working in soft matter, liquid crystals, liquid crystal devices and their applications throughout materials science, chemistry, physics, mathematics and display engineering.

Handbook of Liquid Crystals, Volume 2B by Dietrich Demus,John W. Goodby,George W. Gray,Hans W. Spiess,Volkmar Vill Pdf

The Handbook of Liquid Crystals is a unique compendium of knowledge on all aspects of liquid crystals. In over 2000 pages the Handbook provides detailed information on the basic principles of both low- and high-molecular weight materials, as well as the synthesis, characterization, modification, and applications (such as in computer displays or as structural materials) of all types of liquid crystals. The five editors of the Handbook are internationally renowned experts from both industry and academia and have drawn together over 70 leading figures in the field as authors. The four volumes of the Handbook are designed both to be used together or as stand-alone reference sources. Some users will require the whole set, others will be best served with one or two of the volumes. Volume 1 deals with the basic physical and chemical principles of liquid crystals, including structure-property relationships, nomenclature, phase behavior, characterization methods, and general synthesis and application strategies. As such this volume provides an excellent introduction to the field and a powerful learning and teaching tool for graduate students and above. Volumes 2A and 2B concentrate on low-molecular weight materials, for example those typically used in display technology. A high quality survey of the literature is provided along with full details of molecular design strategies, phase characterization and control, and applications development. These volumes are therefore by far the most detailed reference sources on these industrially very important materials, ideally suited for professionals in the field. Volume 3 concentrates on high-molecular weight, or polymeric, liquid crystals, some of which are found in structural applications and others occur as natural products of living systems. A high-quality literature survey is complemented by full detail of the synthesis, processing, analysis, and applications of all important materials classes. This volume is the most comprehensive reference source on these materials, and is therefore ideally suited for professionals in the field.

Studies on Asymmetric Bent-Core Liquid Crystals by S. Balamurugan,P. Kannan,P. Sudhakara Pdf

The sterically induced packing of bent-shape molecules forms unique smectic phases, which have no counterpart in conventional calamitic liquid crystals. The structural features of the new mesophases observed from these non-chiral molecules may lead to unusual physical properties such as spontaneous polar ordering, superstructural (layer) chirality, supramolecular chirality, and modulated/undulated layer structures. We study structures, polarizing optical microscopy, and electro-optical measurement studies.

Handbook of Liquid Crystals, 8 Volume Set by John W. Goodby,Peter J. Collings,Takashi Kato,Carsten Tschierske,Helen Gleeson,Peter Raynes,Volkmar Vill Pdf

Much more than a slight revision, this second edition of the successful "Handbook of Liquid Crystals" is completely restructured and streamlined, with updated as well as completely new topics, 100% more content and a new team of editors and authors. As such, it fills the gap for a definitive, single source reference for all those working in the field of organized fluids and will set the standard for the next decade. The Handbook's new structure facilitates navigation and combines the presentation of the content by topic and by liquid-crystal type: A fundamentals volume sets the stage for an understanding of the liquid crystal state of matter, while individual volumes cover the main types and forms, with a final volume bringing together the diverse liquid crystal phases through their applications. This unrivaled, all-embracing coverage represents the undiluted knowledge on liquid crystals, making the Handbook a must-have wherever liquid crystals are investigated, produced or used, and in institutions where their science and technology is taught.
