Download or read book Conductivity Fluctuations in Fast Ionic Conductors written by and published by . This book was released on 1990 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical conductivity fluctuations in superionic solids provide a new way of examining transport and electrode properties of solid electrolytes. Of particular interest are the Na Beta and Na Beta double primed aluminas because of their high ionic conductivity, potentially important technological applications, and the ease with which the mobile sodium ions can be exchanged for a number of mono- and di-valent cations. Single crystal and ceramic specimens of sodium, silver, lead, and calcium Beta double primed aluminas, as well as mixed Na/Ag and Na/Ca conductors, have been found to exhibit conductivity fluctuations associated with diffusion of the mobile ions. Also, in the absence of electric current and at frequencies above about 100 Hz Nyquist noise corresponding to the bulk electrolyte resistance is observed. Below 100 Hz noise associated with amalgamation reactions at the electrolyte/contact interface or noise associated with ionic shot noise during the build-up of an electric double layer at the interface are dominant. Experimental diffusion noise levels can be quantitatively explained by focusing on the diffusion of ion-vacancy pairs in single conduction planes. Fluctuations in adjacent planes are correlated and corrections arising from in-plane coulomb forces are negligible.

Download or read book Solid State Electrochemistry written by Peter G. Bruce and published by Cambridge University Press. This book was released on 1997-06-12 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes, for the first time in a modern text, the fundamental principles on which solid state electrochemistry is based. In this sense it is in contrast to other books in the field which concentrate on a description of materials. Topics include solid (ceramic) electrolytes, glasses, polymer electrolytes, intercalation electrodes, interfaces and applications. The different nature of ionic conductivity in ceramic, glassy and polymer electrolytes is described as are the thermodynamics and kinetics of intercalation reactions. The interface between solid electrolytes and electrodes is discussed and contrasted with the more conventional liquid state electrochemistry. The text provides an essential foundation of understanding for postgraduates or others entering the field for the first time and will also be of value in advanced undergraduate courses.
Download or read book Fast Ion Transport in Solids written by B. Scrosati and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main motivation for the organization of the Advanced Research Workshop in Belgirate was the promotion of discussions on the most recent issues and the future perspectives in the field of Solid State lonics. The location was chosen on purpose since Belgirate was the place were twenty years ago, also then under the sponsorship of NATO, the very first international meeting on this important and interdisciplinary field took place. That meeting was named "Fast Ion Transport in Solids" and gathered virtually everybody at that time having been active in any aspect of motion of ions in solids. The original Belgirate Meeting made for the first time visible the technological potential related to the phenomenon of the fast ionic transport in solids and, accordingly, the field was given the name "Solid State lonics". This field is now expanded to cover a wide range of technologies which includes chemical sensors for environmental and process control, electrochromic windows, mirrors and displays, fuel cells, high performance rechargeable batteries for stationary applications and electrotraction, chemotronics, semiconductor ionics, water electrolysis cells for hydrogen economy and other applications. The main idea for holding an anniversary meeting was that of discussing the most recent issues and the future perspectives of Solid State lonics just twenty years after it has started at the same location on the lake Maggiore in North Italy.
Download or read book Science and Technology of Fast Ion Conductors written by Harry L. Tuller and published by Springer. This book was released on 1990 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rediscovery of fast ion conduction in solids in the 1960's stimulated interest both in the scientific community in which the fundamentals of diffusion, order-disorder phenomena and crystal structure evaluation required re-examination, and in the technical community in which novel approaches to energy conversion and chemical sensing became possible with the introduction of the new field of "Solid State Ionics. " Because of both the novelty and the vitality of this field, it has grown rapidly in many directions. This growth has included the discovery of many new crystalline fast ion conductors, and the extension to the fields of organic and amorphous compounds. The growth has involved the extension of classical diffusion theory in an attempt to account for carrier interactions and the development of sophisticated computer models. Diffraction techniques have been refined to detect carrier distributions and anharmonic vibrations. Similar advances in the application of other techniques such as NMR, Raman, IR, and Impedance Spectroscopies to this field have also occurred. The applications of fast ion conducting solid electrolytes have also developed in many directions. High energy density Na/S batteries are now reaching the last stages of development, Li batteries are being implanted in humans for heart pacemakers, and solid state fuel cells are again being considered for future power plants. The proliferation of inexpensive microcomputers has stimulated the need for improved chemical sensors--a major application now being the zirconia auto exhaust sensor being sold by the millions each year.

Download or read book Contact Noise in Superionic Ceramics written by James J. Brophy and published by . This book was released on 1983 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to measure experimentally conductivity fluctuations in fast ionic conductors and to interpret results in terms of transport mechnisms in the solid and and at crystal-electrode interfaces. Electrode propeties are expected to introduce experimental difficulties and it is well established that the electrochemical properties of electrical contacts to solid ionic conductors are conventionally avoided by employing high frequency ac techniques. Conductivity fluctuations, on the other hand, are most easily examined under dc conditions and at low frequencies. A series of experiments has been completed on the low frequency properties of contacts to sodium and silver beta alumina ceramics which give the noise characteristics of contacts alone and demonstrate that suitable electrodes for conductivity fluctutations can be devised.

Download or read book Dynamics of Glassy Crystalline and Liquid Ionic Conductors written by Junko Habasaki and published by Springer. This book was released on 2016-10-19 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the physics of the dynamics of ions in various ionically conducting materials, and applications including electrical energy generation and storage. The experimental techniques for measurements and characterization, molecular dynamics simulations, the theories of ion dynamics, and applications are all addressed by the authors, who are experts in their fields. The experimental techniques of measurement and characterization of dynamics of ions in glassy, crystalline, and liquid ionic conductors are introduced with the dual purpose of introducing the reader to the experimental activities of the field, and preparing the reader to understand the physical quantities derived from experiments. These experimental techniques include calorimetry, conductivity relaxation, nuclear magnetic resonance, light scattering, neutron scattering, and others. Methods of molecular dynamics simulations are introduced to teach the reader to utilize the technique for practical applications to specific problems. The results elucidate the dynamics of ions on some issues that are not accessible by experiments. The properties of ion dynamics in glassy, crystalline and liquid ionic conductors brought forth by experiments and simulations are shown to be universal, i.e. independent of physical and chemical structure of the ionic conductor as long as ion-ion interaction is the dominant factor. Moreover these universal properties of ion dynamics are shown to be isomorphic to other complex interacting systems including the large class of glass-forming materials with or without ionic conductivity.By covering the basic concepts, theories/models, experimental techniques and data, molecular dynamics simulations, and relating them together, Dynamics of Glassy, Crystalline and Liquid Ionic Conductors will be of great interest to many in basic and applied research areas from the broad and diverse communities of condensed matter physicists, chemists, materials scientists and engineers. The book also provides the fundamentals for an introduction to the field and it is written in such a way that can be used for teaching courses either at the undergraduate or graduate level in academic institutions.

Download or read book Chemical Kinetics of Solids written by Hermann Schmalzried and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many different chemical processes take place inside solids or at solid surfaces and interfaces. However, their quantitative description sometimes seems difficult to understand. This book by Professor Schmalzried, author of the eminently successful Solid State Reactions; bridges the gap between the 'physical' and 'chemical' approaches to this subject because it is written in a language which both sides understand. For the first time, a comprehensive coverage of the rapidly developing field of Solid State Kinetics is available. The topics covered in this book go far beyond diffusional transport. Homogeneous and heterogeneous solid-state reactions, phase transitions or the influence of external fields are also treated in detail. With this background, the author explains e.g. charge transport mechanisms in ionic conductors, principles of sensor technology, or oxidation processes clearly and comprehensibly. This book is a must for every solid-state chemist and an indispensable tool for academic and industrial readers alike. From reviews: 'a first-rate reference work that a must for any science library' (J. Am Chem. Soc.) 'can be recommended without restrictions ...' (Z. Phys. Chem.)
Download or read book Boron and Oxygen written by Gert Heller and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present issue, Volume 2 of "Boron Compounds" 4th Supplement of the Gmelin Hand book, updates the previous issues by reporting the literature on boron-oxygen systems published up to 1988. For some important recent developments literature is covered through mid-1992; this concerns, for example, the compounds ~-Ba3[B306h and U[B305J which became of interest as materials with nonlinear optical properties. The volume directly com plements the earlier "Boron Compounds" 3rd Supplement Volume 2. In the original literature, alternative formulations are frequently used for the same com pound. This is especially true for many borates. Often, these species are neither completely heteropolar nor covalent, and an experimentally based decision has not been made. Hence, the use of brackets does not necessarily reflect a truly salt-like character. Volume 1 (systems with hydrogen and noble gases) of this particular supplement will be published subsequently, whereas Volume 3a (boron and nitrogen), Volume 3b (boron and nitrogen, boron and fluorine), and Volume 4 (boron compounds containing Cl, Br, I, S, Se, and Te, as well as a section containing carboranes) have already been published. All volumes of the 4th supplement will be augmented by a formula index. The IUPAC nomenclature is generally adhered to; thf means tetrahydrofuran; and occa sionally additional abbreviations for compounds are explained in the text. Positive signs for chemical shifts of the NMR signals indicates downfield shifts from the references, usually internal (CH3)4Si for olH and 013C with others being specified.

Download or read book Ionic Solids at High Temperatures written by A. M. Stoneham and published by World Scientific. This book was released on 1989 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most studies of solids at high temperatures have concentrated on rare gases or metals. However, in the last few years, the special properties of ionic solids at high temperatures have become increasingly important, with applications to geophysics, ceramic processing, nuclear fuels, solid-state electrolytes, and so on. This volume includes a review by W Hayes and M Hutchings on some of the recent experiments, notably comprehensive work on crystals with fluorite structure, including uranium dioxide. Such experiments can be both difficult to perform and are equally difficult to interpret. There have also been striking developments in the quantitative atomistic theory of defect properties and transport. All these are studied from different aspects in the following three reviews: on anharmonic lattice dynamics using the shell model (R Ball), on the prediction of defect free energies and transport (J Harding) and on dynamical simulations of superionic conductors (M Gillan).
