Available in PDF, EPUB and Kindle. Book excerpt: In solid state physics and in materials science the investigation of the connection between the properties of solids and their microstructure is of major importance. For crystalline materials this connection is related to the lattice structure, and it can be shown convinc ingly that the material properties depend on deviations from the ideal lattice structure in the majority of cases. For this reason a reliable detection and analysis of defects in "nearly perfect" crystals is necessary, and a sufficient spatial resolution of the methods applied is required. Because electrons on the one hand strongly interact with the matter to be investigated and on the other hand can easily be focused electron-optical methods are very advantageous for this purpose. They are used in the diffraction mode, in the imaging mode and in the spectroscopic mode. The attainable high lateral resolution in the imaging mode makes the application of electron microscopy especially effective. Although already valuable information on crystal defects can be gained by using the routine technique of diffraction contrast imagingl-3) which has a resolution of some 4 10 nm - in the special weak-beam technique ) of some nm -, the detection of crystal defects and inhomogeneities, resp. on an atomic or molecular level by the aid of high resolution electron microscopy gets increasing importance.

Book excerpt: Hot-melt extrusion (HME) - melting a substance and forcing it through an orifice under controlled conditions to form a new material - is an emerging processing technology in the pharmaceutical industry for the preparation of various dosage forms and drug delivery systems, for example granules and sustained release tablets. Hot-Melt Extrusion: Pharmaceutical Applications covers the main instrumentation, operation principles and theoretical background of HME. It then focuses on HME drug delivery systems, dosage forms and clinical studies (including pharmacokinetics and bioavailability) of HME products. Finally, the book includes some recent and novel HME applications, scale -up considerations and regulatory issues. Topics covered include: principles and die design of single screw extrusion twin screw extrusion techniques and practices in the laboratory and on production scale HME developments for the pharmaceutical industry solubility parameters for prediction of drug/polymer miscibility in HME formulations the influence of plasticizers in HME applications of polymethacrylate polymers in HME HME of ethylcellulose, hypromellose, and polyethylene oxide bioadhesion properties of polymeric films produced by HME taste masking using HME clinical studies, bioavailability and pharmacokinetics of HME products injection moulding and HME processing for pharmaceutical materials laminar dispersive & distributive mixing with dissolution and applications to HME technological considerations related to scale-up of HME processes devices and implant systems by HME an FDA perspective on HME product and process understanding improved process understanding and control of an HME process with near-infrared spectroscopy Hot-Melt Extrusion: Pharmaceutical Applications is an essential multidisciplinary guide to the emerging pharmaceutical uses of this processing technology for researchers in academia and industry working in drug formulation and delivery, pharmaceutical engineering and processing, and polymers and materials science.

Download or read book Physico Chemical Analysis of Molten Electrolytes written by Vladimir Danek † and published by Elsevier. This book was released on 2006-09-14 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physico-Chemical Analysis of Molten Electrolytes includes selected topics on the measurement and evaluation of physico-chemical properties of molten electrolytes. It describes the features, properties, and experimental measurement of different physico-chemical properties of molten salt systems used as electrolytes for different metal production, metallic layer deposition, as a medium for reactions in molten salts.The physico-chemical properties such as phase equilibria, density (molar volume), enthalpy (calorimetry), surface tension, vapor pressure, electrical conductivity, viscosity, etc. are the most important parameters of electrolytes needed for technological use. For each property the theoretical background, experimental techniques, as well as examples of the latest knowledge and the processing of most important salt systems will be given.The aim of Physico-Chemical Analysis of Molten Electrolytes is not only to present the state of the art on different properties of molten salts systems and their measurement, but also to present the possibilities of modeling molten salt systems, to be able to forecast the properties of an electrolyte mixture from the properties of the pure components in order to avoid experimentally demanding, and in most cases also expensive measurements.This book fills a substantial gap in this field of science. Also documententing the latest research in molten salts chemistry and brings new results and new insights into the study of molten salts systems using the results of X-ray diffraction and XAFS methods, Raman spectroscopy, and NMR measurements. * This book fills a substantial gap in this field of science* Serves as a invaluable reference for all people working in the field of molten salts chemistry* Describes fundamentals of the various properties of molten electrolytes

Book excerpt: The demand for flavourings has been constantly increasing over the last years as a result of the dramatic changes caused by a more and more industrialised life-style: The consumer is drawn to interesting, healthy, pleasurable, exciting or completely new taste experiences. This book draws on the expert knowledge of nearly 40 contributors with backgrounds in both industry and academia and provides a comprehensive insight into the production, processing and application of various food flavourings. Established flavours produced commercially are summarized on a large scale. Methods of quality control and quality management are discussed in detail. The authors also focus on conventional and innovative analytical methods employed in this field and, last but not least, on toxicological, legal, and ethical aspects. Up-to-date references to pertinent literature and an in-depth subject index complete the book.
