Book Description
Thermally stimulated processes include a number of phenomena - either physical or chemical in nature - in which a certain property of a substance is measured during controlled heating from a 'low' temperature. Workers and graduate students in a wide spectrum of fields require an introduction to methods of extracting information from such measurements. This book gives an interdisciplinary approach to various methods which may be applied to analytical chemistry including radiation dosimetry and determination of archaeological and geological ages. In addition, recent advances are included, such as ionic thermocurrent of general order kinetics, polarization thermocurrents and some aspects of the superlinear dependence on the dose of thermoluminescence

Book Description
The field of solid state characterization is central to the pharmaceutical industry, as drug products are, in an overwhelming number of cases, produced as solid materials. Selection of the optimum solid form is a critical aspect of the development of pharmaceutical compounds, due to their ability to exist in more than one form or crystal structure (polymorphism). These polymorphs exhibit different physical properties which can affect their biopharmaceutical properties. This book provides an up-to-date review of the current techniques used to characterize pharmaceutical solids. Ensuring balanced, practical coverage with industrial relevance, it covers a range of key applications in the field. The following topics are included: Physical properties and processes Thermodynamics Intellectual guidance X-ray diffraction Spectroscopy Microscopy Particle sizing Mechanical properties Vapour sorption Thermal analysis & Calorimetry Polymorph prediction Form selection

Book Description
Thermal Analysis (TA) has become an indispensable family of analytical techniques in the polymer research. The increased importance of these techniques can be seen as the result of three more or less parallel developments:• a tempestuous development of TA measuring techniques in combination with a high degree of automation,• the strongly increased understanding of the underlaying theory and,• the increasing knowledge of the relation between the polymers' chemical structure and their physical properties.These areas are still in their developmental stages, especially the third area. The increasing knowledge of the dependence of physical properties on chemical structure just accentuated more and more the need for accurate thermoanalytical measurements, and this knowledge is very important for the first stages of the development of new polymeric systems. Besides, the contribution of TA remains necessary for the technical and commercial development of such a new polymer system. The use of the various TA techniques in these processes is described in this book in nine chapters, while chapter ten illustrates the information obtained about different polymers during special case studies.This book illustrates in this way, applications of a wide variety of TA techniques whilst it is written from a materials characterisation rather than from a TA point of view with attention being paid to the chemical structure/physical properties correlations.

Book Description
McKeever gives us a comprehensive survey of thermoluminescence, an important, versatile, and widely used experimental technique. Bringing together previously isolated specialized approaches, he stresses the importance of the solid state aspects of the phenomenon. The book contains chapters on analysis and special properties, on instrumentation, and on the variety of defect reaction - using the alkali halides and SiO2 as examples - that can take place within a material to yield thermoluminescence. Three chapters concerning applications discuss the features of the solid state reactions to expain some of the properties observed in practice.

Book Description
The book describes and explains thermally stimulated current depolarization and thermal sampling. Electrical charges are created in the dielectric material by a voltage field. Analyzing how the current discharges provides insights into the atomic structure of the polymer, its organization and free volume. The book also includes case studies teaching how to apply the characterization techniques to understand the behavior of polymers.
