Shaped Crystals by Tsuguo Fukuda,Valery I. Chani Pdf

This volume offers an overview of the growth of shaped crystals (oxides, fluorides, etc.) by the micro-pulling-down technique. Both melt and solution (flux) growth are considered. The advantages and disadvantages of the method are discussed in detail and compared with related crystal-growth processes. The authors attempt to give a practical introduction to this technique, thereby also explaining how its application can help to solve problems commonly encountered in other melt-growth methods.

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.

Growth of Crystals by E. Givargizov Pdf

The present volume continues the tradition of the preceding volumes. covering a wide range of crystal growth problems and treating aspects of critical importance for crystalliza tion. Changes in this field of knowledge have. however, changed the criteria for selection of papers for inclusion in this series. The increasing role of crystals in science and technology is even more apparent today. The study and utilization of these highly perfect objects of nature considerably facilitates progress in the physics and chemistry of solids. quantum electronics, optics, microelectron ics, and other sciences. The demand for crystals and crystal devices has grown steadily and has led to the emergence and rapid growth of the single crystal industry (we can safely saythat the state ofthe art in this industry is indicative ofthe overall scientific and technolo- cal potential of a country). At the same time, the introduction of crystallization techniques into other industries is gaining ever-increasing importance. To illustrate this last state ment, we can mention the fabrication of textured structural materials and direct methods of metal reduction in ores by using chemical vapor transport techniques. Crystallization tech ll niques progress both in "width" and in "depth : traditional methods are modernized. and novel techniques appear, some of them at the junction of the already existing technologies (for example, flux growth of crystals, growth from vapor with participation of the liquid phase, etc. ).

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.

Crystals: Their Role in Nature and in Science provides the description of the phenomena and concepts and essential facts and ideas in the study of crystals. The book is divided into two parts. Part 1 discusses the growth and various forms of crystals. Under this section, topics on the etymology of the word "crystal", the existence of crystals, how crystals grow, stacking patterns, and various crystal symmetries are presented. Part 2 covers the crystal structure and how it interacts with light and X-rays. This part discusses some strange light effects that some crystals make; the production of beautiful and scientifically significant color patterns; the possible types of space patterns in crystals; and the use of X-ray in finding the details of the internal atomic pattern of crystals. Crystallographers and laymen interested in the study and appreciation of crystals will find the book invaluable.

Enlightenment on Crystals, Gems, and Metal Magic by Dayanara Blue Star Pdf

Since back in prehistoric times, men and women have found the mystery, beauty, and power of stones irresistible. Just as an herbalist understands the powers of herbs, the practitioner of magic understands the powers of gems, crystals, and metals. They used this knowledge to change themselves and their very lives. Some may find it hard to believe that there is positive power within gems, crystals, stones, or metals. Yet, they totally accept the energy we get from food and the healing power of plants and herbs. It doesn't take such a leap of faith to believe that energy is inherent in all the earth and its fullness. Understanding those energies from the earth, which we are from as well, and then directing them for our better good - that is Magic. Magic is all about change. Without the need for change, there would be no need for magic. Making use of the energy all around us is folly to some, but others see the wisdom. The magician's philosophy is that all we are and all we see was given freely to us by an original source, to learn about and use for our good. Religion itself was born out of a set of beliefs shared by a particular group of people. Belief is the strongest force on the planet. Why else would men fight and die if they didn't believe in what they were fighting for? It is what we believe that moves our lives in the directions they go. Change your belief and you change your world. Energy from gems, stones, and metals help people do this.

Physics and Chemistry of Finite Systems: From Clusters to Crystals by Peru Jena,S.N. Khanna,B.K.N. Rao Pdf

Recent innovations in experimental techniques such as molecular and cluster beam epitaxy, supersonic jet expansion, matrix isolation and chemical synthesis are increasingly enabling researchers to produce materials by design and with atomic dimension. These materials constrained by sire, shape, and symmetry range from clusters containing as few as two atoms to nanoscale materials consisting of thousands of atoms. They possess unique structuraI, electronic, magnetic and optical properties that depend strongly on their size and geometry. The availability of these materials raises many fundamental questions as weIl as technological possibilities. From the academic viewpoint, the most pertinent question concerns the evolution of the atomic and electronic structure of the system as it grows from micro clusters to crystals. At what stage, for example, does the cluster look as if it is a fragment of the corresponding crystal. How do electrons forming bonds in micro-clusters transform to bands in solids? How do the size dependent properties change from discrete quantum conditions, as in clusters, to boundary constrained bulk conditions, as in nanoscale materials, to bulk conditions insensitive to boundaries? How do the criteria of classification have to be changed as one goes from one size domain to another? Potential for high technological applications also seem to be endless. Clusters of otherwise non-magnetic materials exhibit magnetic behavior when constrained by size, shape, and dimension. NanoscaIe metal particles exhibit non-linear opticaI properties and increased mechanical strength. SimiIarly, materials made from nanoscale ceramic particIes possess plastic behavior.
