Book Description
This new textbook provides for the first time a comprehensive treatment of the basics of contemporary crystallography and crystal growth in a single volume. The reader will be familiarized with the concepts for the description of morphological and structural symmetry of crystals. The architecture of crystal structures of selected inorganic and molecular crystals is illustrated. The main crystallographic databases as data sources of crystal structures are described. Nucleation processes, their kinetics and main growth mechanism will be introduced in fundamentals of crystal growth. Some phase diagrams in the solid and liquid phases in correlation with the segregation of dopants are treated on a macro- and microscale. Fluid dynamic aspects with different types of convection in melts and solutions are discussed. Various growth techniques for semiconducting materials in connection with the use of external field (magnetic fields and microgravity) are described. Crystal characterization as the overall assessment of the grown crystal is treated in detail with respect to - crystal defects - crystal quality - field of application Introduction to Crystal Growth and Characterization is an ideal textbook written in a form readily accessible to undergraduate and graduate students of crystallography, physics, chemistry, materials science and engineering. It is also a valuable resource for all scientists concerned with crystal growth and materials engineering.

Book Description
Synthesis, Crystal Growth and Characterization presents the proceedings of the International School on Synthesis, Crystal Growth and Characterization of Materials for Energy Conversion and Storage, held on October 12-23, 1981, at the National Physical Laboratory in New Delhi, India. The book consists of lectures by distinguished scientists from around the world who tackle different aspects of synthesis, crystal growth, characterization of materials, energy conversion, and energy storage. Organized into four parts encompassing 26 chapters, the book begins with an overview of the synthesis of materials at high temperatures and pressures before turning to a discussion of how macrocrystalline and amorphous silicon is prepared. It then looks at fundamental principles underlying the process of crystal growth, both from the vapor phase and from melt, and methodically introduces the reader to the different techniques used to characterize materials, including neutron scattering and electron transport. The next chapters focus on point defects and aggregates that influence the critical electronic properties of semiconducting materials, X-ray diffraction studies of strains and stresses in thin films used in solid-state devices, and electron spectroscopic studies of solid surfaces. The book also considers the role of physics in microelectronics and vice versa, fast ion transport in solids, and the concept of Syadvada in relation to modern physics. This volume is a valuable resource for participants of the International School on Synthesis, Crystal Growth and Characterization of Materials for Energy Conversion and Storage, as well as active researchers working in areas related to the field.

Book Description
Calorimetry, as a technique for thermal analysis, has a wide range of applications which are not only limited to studying the thermal characterisation (e.g. melting temperature, denaturation temperature and enthalpy change) of small and large drug molecules, but are also extended to characterisation of fuel, metals and oils. Differential Scanning Calorimetry is used to study the thermal behaviours of drug molecules and excipients by measuring the differential heat flow needed to maintain the temperature difference between the sample and reference cells equal to zero upon heating at a controlled programmed rate. Microcalorimetry is used to study the thermal transition and folding of biological macromolecules in dilute solutions. Microcalorimetry is applied in formulation and stabilisation of therapeutic proteins. This book presents research from all over the world on the applications of calorimetry on both solid and liquid states of materials.

Book Description
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.

Book Description
The intrinsic properties of a solid, i. e. , the properties that result from its specific structure, can be largely modified by crystallographic and chem ical defects. The formation of these defects is governed by the heat and mass transfer conditions which prevail on and near a crystal-nutrient in terface during crystallization. Hence, both the growth of highly perfect crystals and the preparation of samples having predetermined defect-induced (extrinsic) properties require a thorough understanding of the reaction and transport mechanisms that govern crystallization from vapors, solutions and melts. Crystal growth, as a science, is therefore mostly concerned with the chemistry and physics of heat and mass transport in these fluid-solid phase transitions. Solid-solid transitions are, at this time, not widely employed for high quality single-crystal production. Transport concepts are largely built upon equilibrium considerations, i. e. , on thermodynamic and phase equilibrium concepts. Hence to supply a "workable" foundation for the succeeding discussions, this text begins in Chapter 2 with a concise treatment of thermodynamics which emphasizes applications to mate rials preparation. After working through this chapter, the reader should feel at ease with often (particularly among physicists) unfamiliar entities such as chemical potentials, fugacities, activities. etc. Special sections on ther mochemical calculations (and their pitfalls) and compilations of thermochemi cal data conclude the second chapter. Crystal growth can be called. in a wide sense, the science and technology of controlling phase transitions that lead to (single crystalline) solids.
