Download or read book Crystallography written by Walter Borchardt-Ott and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a self-study guide, course primer or teaching aid, Bor- chardt-Ott's Crystallography is the perfect textbook for students and teachers alike. In fact, it can be used by chemists, mineralogists, physicists and geologists. Based on the author's more than 20 years of teaching experience, the book has numerous line drawings designed especially for the text and a large number of exercises - with solutions - at the end of each chapter. The fourth edition of the original German text has been translated into English for an international readership. The heart of the book is firmly fixed in geometrical crystallography. It is from the concept of the space lattice that symmetry operations, Bravais lattices, space groups and point groups are all developed. Molecular symmetry and crystal formsare treated. Much emphasis is placed on the correspondence between point groups and space groups. The sections on crystal chemistry and X-ray diffraction are intended as an introduction to these fields.

Download or read book Morphology of Crystals written by Ichiro Sunagawa and published by Springer Science & Business Media. This book was released on 1988-02-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular mechanisms underlying the fact that a crystal can take a variety of external forms is something we have come to understand only in the last few decades. This is due to recent developments in theoretical and experimental investigations of crystal growth mechanisms. Morphology of Crystals is divided into three separately available volumes. Part A contains chapters on roughening transition; equilibrium form; step pattern theory; modern PBC; and surface microtopography. This part provides essentially theoretical treatments of the problem, particularly the solid-liquid interface. Part B contains chapters on ultra-fine particles; minerals; transition from polyhedral to dendrite; theory of dendrite; and snow crystals. All chapters are written by world leaders in their respective areas, and some can be seen as representing the essence of a life's work. This is the first English-language work which covers all aspects of the morphology of crystals - a topic which has attracted top scientific minds for centuries. As such, it is indispensable for anyone seeking an answer to a question relating to this fascinating problem: mineralogists, petrologists, crystallographers, materials scientists, workers in solid-state physics and chemistry, etc. In Parts A: Fundamentals and B: Fine Particles, Minerals and Snow equilibrium and kinetic properties of crystals are generally approached from an `atomistic' point of view. In contrast, Part C: The Geometry of Crystal Growth follows the alternative and complementary `geometrical' description, where bulk phases are considered as continuous media and their interfaces as mathematical surfaces with orientation-dependent properties. Equations of motion for a crystal surface are expressed in terms of vector and tensor operators working on surface free energy and growth rate, both expressed as functions of surface orientation and driving force, or `affinity' for growth. This approach emphasizes the interrelation between equilibrium and kinetic behavior. Part 1 establishes the theoretical framework. Part 2 gives a construction toolbox for explicit (analytic) functions. An extra chapter is devoted to experimental techniques for measuring such functions: a new approach to sphere growth experiments. The emphasis throughout is on principles and new concepts. Audience: Advanced readers familiar with traditional aspects of crystal growth theory. Can be used as the basis for an advanced course, provided supplementation is provided in the areas of atomistic models of the advancing surface, diffusion fields, etc.

Download or read book Morphology and Crystal Structure of Random Main Chain Semi flexible Thermotropic Liquid Crystal Polymers written by Susan Louise Kent and published by . This book was released on 1992 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crystal structure and morphology of random, main chain, thermotropic liquid crystal polymers (LCP's) of equimolar amounts of the following structural units (with n equal to 4, 5, 6 and 7 in "A") have been examined by electron microscopy and diffraction:(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) When crystallized from the liquid crystal state in the form of thin films, the polymer forms a 50-70A lamellar texture. Electron diffraction reveals an orthorhombic unit cell (a = 8.34A and b = 5.10A). Similar results were obtained with the 4, 6 and 7 carbon spacer LCP's. The observations can only be interpreted in terms of chain folding, the flexibility of the "spacer" along the polymers backbone permitting folding to occur. High temperature electron diffraction shows little change in positional ordering above the crystal-liquid crystal transition temperature. Rapid quenching from the liquid crystal state produces a ribbon-like morphology with the molecules oriented perpendicular to the long direction of the ribbons. Shearing the 7 carbon spacer LCP in the liquid crystal state results in $sim$150A lamellar crystals normal to the shear direction. The lamellae readily shear over one another, suggesting the presence of adjacent reentry chain folding. Single crystals of the 7 carbon flexible spacer LCP have been grown from dilute solution. This is the first report of solution grown single crystals of a liquid crystalline polymer. The crystals thicken (from $sim$100A to 190A) upon annealing below their crystal-liquid crystal melting temperature. Annealing in the liquid crystalline state produces unusual and unique morphologies. Extruded pellets of the 7 carbon flexible spacer LCP resemble a composite material with 0.2 $-$ 1.8$mu$m "fibers" oriented parallel to the extrusion direction. Etching revealed a lamellar morphology with the lamellae (50-1,800A) oriented perpendicular to the fiber extrusion direction. Thinner lamellae (50-130A) were observed on the surface of compression-molded articles with thicker, presumably extended chain lamellae, observed in the interior. Selected area electron diffraction confirms that the molecular axes are perpendicular to the lamellae. The results suggest significant degrees of chain folding in the liquid crystal state since it is unexpected that previously extended, nematically packed chains would fold during the liquid crystal-crystal transition.

Download or read book Engineering Crystallography From Molecule to Crystal to Functional Form written by Kevin J. Roberts and published by Springer. This book was released on 2017-07-18 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the current state-of-the-art regarding the application of applied crystallographic methodologies for understanding, predicting and controlling the transformation from the molecular to crystalline state with the latter exhibiting pre-defined properties. This philosophy is built around the fundamental principles underpinning the three inter-connected themes of Form (what), Formation (how) and Function (why). Topics covered include: molecular and crystal structure, chirality and ferromagnetism, supramolecular assembly, defects and reactivity, morphology and surface energetics. Approaches for preparing crystals and nano-crystals with novel physical, chemical and mechanical properties include: crystallisation, seeding, phase diagrams, polymorphic control, chiral separation, ultrasonic techniques and mechano-chemistry. The vision is realised through examination of a range of advanced analytical characterisation techniques including in-situ studies. The work is underpinned through an unprecedented structural perspective of molecular features, solid-state packing arrangements and surface energetics as well as in-situ studies. This work will be of interest to researchers, industrialists, intellectual property specialists and policy makers interested in the latest developments in the design and supply of advanced high added-value organic solid-form materials and product composites.
