This book was released on 2010-10-26 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book by Lev M. Blinov is ideal to guide researchers from their very first encounter with liquid crystals to the level where they can perform independent experiments on liquid crystals with a thorough understanding of their behaviour also in relation to the theoretical framework. Liquid crystals can be found everywhere around us. They are used in virtually every display device, whether it is for domestic appliances of for specialized technological instruments. Their finely tunable optical properties make them suitable also for thermo-sensing and laser technologies. There are many monographs written by prominent scholars on the subject of liquid crystals. The majority of them presents the subject in great depth, sometimes focusing on a particular research aspect, and in general they require a significant level of prior knowledge. In contrast, this books aims at an audience of advanced undergraduate and graduate students in physics, chemistry and materials science. The book consists of three parts: the first part, on structure, starts from the fundamental principles underlying the structure of liquid crystals, their rich phase behaviour and the methods used to study them; the second part, on physical properties, emphasizes the influence of anisotropy on all aspects of liquid crystals behaviour; the third, focuses on electro-optics, the most important properties from the applications standpoint. This part covers only the main effects and illustrates the underlying principles in greater detail. Professor Lev M. Blinov has had a long carrier as an experimentalist. He made major contributions in the field of ferroelectric mesophases. In 1985 he received the USSR state prize for investigations of electro-optical effects in liquid crystals for spatial light modulators. In 1999 he was awarded the Frederiks medal of the Soviet Liquid Crystal Society and in 2000 he was honoured with the G. Gray silver medal of the British Liquid Crystal Society. He has held many visiting academic positions in universities and laboratories across Europe and in Japan.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Liquid crystal phases exhibit physical characteristics that lie between those of liquid and crystal phases. The many liquid crystal sub-phases are defined based on the degree of positional and orientational ordering the molecules have and the materials that make up these liquid crystal phases. This thesis presents a study of the molecular packing and physical properties of complex liquid crystal phases using dopants to better examine the stability and packing mechanisms of these phases. It also looks at the dispersion of quantum dots in liquid crystal materials, examining the electro-optical properties of the mixtures. The main goal of this thesis is to examine the effects of dopants on the properties of liquid crystal phases using optical microscopy, differential scanning calorimetry, electro-optical measurements, and X-ray scattering. For those mixtures with quantum dots fluorescence microscopy and photoluminescence measurements were also conducted. Rod-like liquid crystals are commonly used in display applications when the material is in a nematic liquid crystal phase, which is the least ordered phase exhibiting no positional ordering. The more complicated chiral smectic liquid crystal phases, which have a one dimensional layer structure, show potential for faster and tri-stable switching. A chiral rod-like liquid crystal material is doped with both chiral and achiral rod-like liquid crystals to examine the stability of one of the chiral smectic sub-phase, the SmC*FI1 phase. This phase consists of tilted molecules rotating about the cone defined by the tilt angle with a periodicity of three layers and an overall helical structure.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Liquid Crystal Research and Applications, Volume 1 is a collection of papers presented at the Third Liquid Crystal Conference of the Socialist Countries, held in Budapest on August 27-31, 1979. This volume is comprised of three parts. The first part deals with the phases and structures of liquid crystals through methods employing synthesis, X-ray studies, electron diffraction, and calorimetric determination. The second part discusses molecular dynamics and dynamical methods where mostly dielectric investigations into liquid crystal properties are emphasized. This part includes the developments in the study of molecular dynamics in liquid crystals. Other topics presented in this part are the acousto-optical and ultrasonic relaxation methods. The third part covers the continual properties of liquid crystals: their properties and behavior when exposed to different testing methods and variables. For example, a correlation between viscosity coefficients of starting components and those of their mixtures is attempted, resulting when MBBA and EBBA in different percentages are mixed, that none of their coefficients is found to obey any pronounced law. However, the viscosity coefficients given in the table may serve as reference data for further studies. Physicists; process engineers; and graduate students in physics, chemistry, and materials science fields; and university professors and lecturers related to studies in the field of liquid crystals will find this collection of papers highly informative and rewarding.

This book was released on 2012-12-06 with total page 1133 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Liquid Crystals and Ordered Fluids written by Julian F. Johnson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Structure of Liquid Crystal Phases written by P. S. Pershan and published by World Scientific. This book was released on 1988 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current understanding of different phases as well as the phase transitions between them has only been achieved following recent theoretical advances on the effects of dimensionality in statistical physics. P S Pershan explains the connection between these two separate areas and gives some examples of problems where the understanding is still not complete. The most important example is the second order phase transition between the nematic and smectic-A phase. Others include the relation between the several hexatic phases that have been observed and the first order restacking transitions between phases that were all previously identified as smectic-B, but which should more properly be identified as crystalline-B. Some relatively recent experimental developments on the discotic phase, liquid crystal surfaces and lyotropic phases are also included. The book includes 41 major reprints of some of the recent seminal work on the structure of liquid crystals. They are introduced by a brief review of the symmetries and other properties of liquid crystalline phases. In addition, there is a discussion of the differences between true liquid crystalline phases and others that were described as liquid crystalline in the early literature, but which have since been shown to be true three-dimensional crystals. The progression from the isotropic fluid, through the nematic, smectic, and various crystalline phases can be understood in terms of a systematic decrease in symmetry, together with an accompanying variation in structure is explained. A guide to the selected reprints and a sort of ?Rosetta Stone? for these various phases is provided. The goal of this book is to explain the systematics of this progression to students and others that are new to this field, as well as to provide a useful handbook for people already working in the field.

Available in PDF, EPUB and Kindle. Book excerpt: The JLCS Excellent Book Award 2021 by Japanese Liquid Crystal SocietyIn nature, a number of molecules self-assemble to form various aggregation states. In these aggregation states, numerous functions, which have never been observed in one molecule, are developed. Even for the same compound, the different aggregation states exhibit totally different physical properties in density, hardness, optical and electrical properties, medicinal effect, etc. For pursuing the functionality of materials, it may be indispensable to understand the molecular aggregation states of crystals, liquid crystals, glass, colloids, etc. In this book, the author will focus on the basis of polymorphic phenomena of crystals and liquid crystals and their physical properties. After reading this book, you will be able to change your viewpoint of matter from traditional limited 'three states of matter' to novel 'numerous states of matter.'
