New Developments in Liquid Crystals Research by Anka Trajkovska Petkoska Pdf

Liquid crystals (LCs) were discovered over a century ago, but their profound impact was in the past four decades through their successful implementation into electronic devices that we are using every day. The research on liquid crystals actively continues in the 21st century and offers unlimited potential in various display or non-display applications. This book covers novel topics related to LCs and is intended for a wide range of researchers in both, academia and industry, from beginners to advanced level professionals in many scientific areas, viz. materials science and engineering, chemistry, physics, optics, photonics, nanotechnology, electrical engineering, and so on. The book contains topics on nematic and cholesteric LCs, in the form of films or particles, as well as modified LC behaviour with variety of dopants, micron and nano-sized particles, microencapsulation of LC particles and modelling of their behaviour under an externally applied field. Topics related to the effect on nanomaterials on LC behaviour, as well as structural and magnetic properties of different types of iron-containing liquid crystals (metallo-mesogens) are covered, as well. Finally, an overview of different alignment technologies for nematic liquid crystals such as mechanical rubbing of polymer films, obliquely-deposited inorganic films, photo-irradiated, IB-bombarded and patterned surfaces, are briefly reviewed along with several novel alignment concepts. The state of the art in respective fields related to LCs in each chapter is given by leading experts.

Progress In Liquid Crystal (Lc) Science And Technology: In Honor Of Kobayashi's 80th Birthday by Kwok Hoi-sing,Naemura Shohei,Ong Hiap Liew Pdf

The presence of liquid crystal displays (LCDs) marks the advances in mobile phones and television development over the last few decades. Japanese companies were the first to commercialize passive-matrix TNLCDs and, later on, high-resolution activematrix LCDs.Prof. Shunsuke Kobayashi has made essential contributions to Japan's prominence in LCD development throughout this period. He is well-known not only for his own groundbreaking research, but also for the training of many prominent figures in the display industry, both in Japan and in other countries.This book brings together many prominent researchers in the field of liquid crystal science and technology, to share with us the key developments in LCD over the last few decades. It comprises of five categories — from basic physics and chemistry of liquid crystals, to detailed descriptions of alignment technologies, wide viewing angle technologies, LC optics, and display applications.The Slottow-Owaki Prize is awarded for outstanding contributions to the education and training of students and professionals in the field of information displays. This year, the award recipient is Dr. Hoi-Sing Kwok, SID fellow and professor at Hong Kong University, for providing education and training in display technology to many students and professionals in Asia through the creation of a display research center at the Hong Kong University of Science and Technology.

Applications of Liquid Crystals by G. Meier,E. Sackmann,J.G. Grabmaier Pdf

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.

Polymer Liquid Crystals by A Ciferri Pdf

Polymer Liquid Crystals covers the significant developments in the field of highlight oriented polymers. This 12-chapter book emerged from lectures presented during the seminar "Polymer Liquid Crystals: Science and Technology", held at Santa Margherita Ligure, Italy on May 19-23, 1981. The opening chapters highlight the molecular basis of liquid crystallinity. The subsequent chapters deal with the synthesis, structure, properties, and macroscopic phenomena of polymer liquid crystals. These topics are followed by descriptions of the orientation of liquid crystals, specifically the instabilities in low molecular weight nematic and cholesteric liquid crystals. The final chapters consider the applications of these crystals to display devices and the advances in high-strength fibers and molecular composites. This book will be of great value to polymer liquid crystal chemists and researchers.

Liquid Crystals and Ordered Fluids by Julian F. Johnson,Roger S. Porter Pdf

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.

Liquid Crystal Sensors by Albert Schenning,Gregory P. Crawford,Dirk J. Broer Pdf

Liquid Crystal Sensors discusses novel applications of liquid crystals that lie beyond electrically driven optical switches and displays. The main focus is on recent progress in the area of sensors based on low molar mass and polymer liquid crystals. This area of research became "hot" in recent years since the possibilities for applications of liquid crystal sensors are growing in many areas, ranging from the detection of mechanical displacements to the detection of environmental pollutants and chemical agents. This book is well-suited for students, as well as scientists from different backgrounds. For students and researchers new to the field, it gives a thorough introduction. For experienced researchers it shows the latest breakthroughs and serves as an inspiration for solving problems or sparking new ideas. Key Features: Emphasizes how liquid crystals are extremely sensitive to external stimuli and therefore can be used for the construction of stimuli-responsive devices, such as sensors Includes the contributions of editors who are deeply involved in the field and author chapters on hot topics such as the sensitivity of liquid crystals to pollutants, UV light, and strain Provides an exclusive on LC sensors where having the data in one place will be very useful to the community Gives more information on sensors and broadens the scope by having a contributed volume rather than authored Combines recent data on advances in the area of liquid crystal sensors that includes many types of liquid crystal materials
