Download or read book Fast Scanning Calorimetry written by Christoph Schick and published by Springer. This book was released on 2016-06-28 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, the scan rate range of calorimeters has been extended tremendously at the high end, from approximately 10 up to 10 000 000 °C/s and more. The combination of various calorimeters and the newly-developed Fast Scanning Calorimeters (FSC) now span 11 orders of magnitude, by which many processes can be mimicked according to the time scale(s) of chemical and physical transitions occurring during cooling, heating and isothermal stays in case heat is exchanged. This not only opens new areas of research on polymers, metals, pharmaceuticals and all kinds of substances with respect to glass transition, crystallization and melting phenomena, it also enables in-depth study of metastability and reorganization of samples on an 1 to 1000 ng scale. In addition, FSC will become a crucial tool for understanding and optimization of processing methods at high speeds like injection molding. The book resembles the state-of-the art in Thermal Analysis & Calorimetry and is an excellent starting point for both experts and newcomers in the field.
Download or read book Modulated Temperature Differential Scanning Calorimetry written by Mike Reading and published by Springer Science & Business Media. This book was released on 2006-02-22 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: MTDSC provides a step-change increase in the power of calorimetry to characterize virtually all polymer systems including curing systems, blends and semicrystalline polymers. It enables hidden transitions to be revealed, miscibility to be accurately assessed, and phases and interfaces in complex blends to be quantified. It also enables crystallinity in complex systems to be measured and provides new insights into melting behaviour. All of this is achieved by a simple modification of conventional DSC. In 1992 a new calorimetric technique was introduced that superimposed a small modulation on top of the conventional linear temperature program typically used in differential scanning calorimetry. This was combined with a method of data analysis that enabled the sample’s response to the linear component of the temperature program to be separated from its response to the periodic component. In this way, for the first time, a signal equivalent to that of conventional DSC was obtained simultaneously with a measure of the sample’s heat capacity from the modulation. The new information this provided sparked a revolution in scanning calorimetry by enabling new insights to be gained into almost all aspects of polymer characteristics. This book provides both a basic and advanced treatment of the theory of the technique followed by a detailed exposition of its application to reacting systems, blends and semicrystalline polymers by the leaders in all of these fields. It is an essential text for anybody interested in calorimetry or polymer characterization, especially if they have found that conventional DSC cannot help them with their problems.

Available in PDF, EPUB and Kindle. Book excerpt: Differential Scanning Calorimetry (DSC) is a well established measuring method which is used on a large scale in different areas of research, development, and quality inspection and testing. Over a large temperature range, thermal effects can be quickly identified and the relevant temperature and the characteristic caloric values determined using substance quantities in the mg range. Measurement values obtained by DSC allow heat capacity, heat of transition, kinetic data, purity and glass transition to be determined. DSC curves serve to identify substances, to set up phase diagrams and to determine degrees of crystallinity. This book provides, for the first time, an overall description of the most impor tant applications of Differential Scanning Calorimetry. Prerequisites for reliable measurement results, optimum evaluation of the measurement curves and esti mation of the uncertainties of measurement are, however, the knowledge of the theoretical bases of DSC, a precise calibration of the calorimeter and the correct analysis of the measurement curve. The largest part of this book deals with these basic aspects: The theory of DSC is discussed for both heat flux and power compensated instruments; temperature calibration and caloric calibration are described on the basis of thermodynamic principles. Desmearing of the measurement curve in different ways is presented as a method for evaluating the curves of fast transitions.

Download or read book Application of the High Temperature Calorimeter to the Determination of the Heats of Formation of Na Sn and Li Sn Alloys written by and published by . This book was released on 1949 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method has been devised for using the high frequency induction coil as a high temperature calorimeter. The method enables one to determine the heat effects produced at high temperatures. The method has been applied to the determination of the heats of formation of the alloys Na-Sn and Li-Sn. The average heat of formation (delta H) determined for Na-Sn is -9.63 +/= 0.40 hilocalories per mole at 8730 K. This value becomes -10.6 +/= 0.6 kilocalories per mole when extrapolated to 298 deg K. The average heat of formation (delta H) determined for Li-Sn is -17.57 +/= 0.83 kilocalories per mole at 850 deg K. This value becomes -18.62 +/= 1.50 kilocalories per mole when extrapolated to 298 deg K. These results are compared with the results of other investigators.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in High Temperature Chemistry, Volume 1 describes the complexities and special and changing characteristics of high temperature chemistry. After providing a brief definition of high temperature chemistry, this nine-chapter book goes on describing the experiments and calculations of diatomic transition metal molecules, as well as the advances in applied wave mechanics that may contribute to an understanding of the bonding, structure, and spectra of the molecules of high temperature interest. The next chapter provides a summary of gaseous ternary compounds of the alkali metals used in high temperature chemistry. This topic is followed by discussions on the thermochemical properties of some simple solids in terms of valence states of the metallic elements and of the electrons in metals, on anions, and in aqueous solutions. Other chapters are concerned with the stepwise bond dissociation energies in a number of polyvalent metal fluorides and the unique possibilities for chemical syntheses, which are available through high temperature species. The final chapters are devoted to the techniques, temperature ranges, and accuracy of high temperature calorimetry. These chapters also include surveys on the nature of thermal plasmas for high temperature chemistry. This book is of benefit to high temperature chemists and specialized engineers.
Download or read book Theory of Calorimetry written by W. Zielenkiewicz and published by Springer Science & Business Media. This book was released on 2006-01-02 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calorimetry is one of the oldest areas of physical chemistry. The date on which calorimetry came into being may be taken as 13 June 1783, the day on which Lavoisier and Laplace presented a contribution entitled ,,Memoire de la Chaleur“ at a session of the Academie Française. Throughout the existence of calorimetry, many new methods have been developed and the measuring techniques have been improved. At p- sent, numerous laboratories worldwide continue to focus attention on the development and applications of calorimetry, and a number of com- nies specialize in the production of calorimeters. The calorimeter is an instrument that allows heat effects in it to be determined by directly measurement of temperature. Accordingly, to determine a heat effect, it is necessary to establish the relationship - tween the heat effect generated and the quantity measured in the ca- rimeter. It is this relationship that unambiguously determines the mathematical model of the calorimeter. Depending on the type of ca- rimeter applied, the accuracy required, and the conditions of heat and mass transfer that prevail in the device, the relationship between the measured and generated quantities can assume different mathematical forms.
