Download or read book Acoustic, Thermal Wave and Optical Characterization of Materials written by G.M. Crean. This book was released on 2014-08-04. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on a variety of novel non-destructive techniques for the characterization of materials, processes and devices. Emphasis is placed on probe-specimen interactions, in-situ diagnosis, instrumentation developments and future trends. This was the first time a symposium on this topic had been held, making the response particularly gratifying. The high quality of the contributions are a clear indication that non-destructive materials characterization is becoming a dynamic research area in Europe at the present time.A selection of contents: The role of acoustic properties in designs of acoustic and optical fibers (C.K.

Book Synopsis Photothermal Spectroscopy Methods for Chemical Analysis by : Stephen E. Bialkowski

Download or read book Photothermal Spectroscopy Methods for Chemical Analysis written by Stephen E. Bialkowski. This book was released on 1996-01-12. Available in PDF, EPUB and Kindle. Book excerpt: A unique guide to the application and theory of photothermalspectroscopy. This book debunks the myth that photothermal spectroscopy is toocomplicated for practical application to chemical analysis, anddemonstrates the advantages this technique has over conventionalspectroscopy in facilitating extremely sensitive measurements ofoptical absorption in homogeneous media. The book covers thesubject from the ground up, lists all practical considerationsneeded to obtain accurate results, and provides a working knowledgeof the various methods in use--including photo acoustics andphotopyroelectric techniques. Bringing together a wealth of information that has been scatteredthroughout the professional literature, Photothermal SpectroscopyMethods for Chemical Analysis covers methods and information thatshould be known to every analytical chemist, including: * Descriptions of photothermal spectroscopy using a consistentmathematical language * Helpful examples from the literature of analytical applicationsand current research * Illustrations of all important points, consistent equations, andnumerous original figures * A discussion of laser technology and how it is used to obtainaccurate results from extremely small samples of a few molecules * Everything spectroscopists need to know to construct their ownapparatus and use it to conduct successful experiments * Tips on how to interpret experimental results effectively whenusing nonlinear processes and in many other situations inphotothermal spectroscopy * Considerations for further study of heterogeneous sampleanalysis * Unified nomenclature of the patchwork of terms used byresearchers in analytical and physical chemistry, physics, andoptical engineering * Equations that are derived with the aid of a symbolic languageprocessor to ensure correct results Photothermal spectroscopy has seen major advances since the adventof laser technology twenty-five years ago. It is now possible,using a laser's coherent and powerful output, to obtain extremelysensitive measurements of optical absorption that exceed those ofmass spectroscopy by two or three times, and produce accurateresults from only a few molecules. Focusing on samples in homogeneous media, this book provides aunique guide--incorporating theory and application--to allavailable photothermal spectroscopy techniques for chemical andmaterial analysis. It uses a systematic approach in itscomprehensive treatment of the theory, and covers all the necessarybackground material, from laser optics to fluid dynamics. This accessible text describes the various processes used to detectthermal perturbation of a sample, ranging from optical excitationto nonlinear processes, and covers all optical principles necessaryto understand photothermal spectroscopy. When dealing withhydrodynamic equations that govern energy transfer in the samplematrix, it provides an original impulse-response approach. Inaddition, the book explains how to construct the apparatus oneneeds to conduct successful photothermal experiments, sincecommercial equipment is not available as in conventionalspectrophotometry. Throughout, this book draws on information from a wide range offields, including analytical spectroscopy, measurement physics,physical optics, and chemical dynamics. Providing clearexplanations at every turn, the author demonstrates a completeunderstanding of the theory and applications as a firm basis forthe correct interpretation of experimental results. For analytical chemists, as well as for students at the graduatelevel, Photothermal Spectroscopy Methods for Chemical Analysis isan unmatched resource that develops a consistent mathematical basisfor signal description, consolidates previous theories, andprovides invaluable insight into laser technology.

Download or read book Characterization of Metals and Alloys written by Ramiro Pérez Campos. This book was released on 2016-10-24. Available in PDF, EPUB and Kindle. Book excerpt: This book covers various aspects of characterization of materials in the areas of metals, alloys, steels, welding, nanomaterials, intermetallic, and surface coatings. These materials are obtained by different methods and techniques like spray, mechanical milling, sol-gel, casting, biosynthesis, and chemical reduction among others. Some of these materials are classified according to application such as materials for medical application, materials for industrial applications, materials used in the oil industry and materials used like coatings. The authors provide a comprehensive overview of structural characterization techniques including scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectroscopy, image analysis, finite element method (FEM), optical microscopy (OM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), differential scanning calorimetry (DSC), ultraviolet–visible spectroscopy (UV-Vis), infrared photo-thermal radiometry (IPTR), electrochemical impedance spectroscopy (EIS), thermogravimetry analysis (TGA), thermo luminescence (TL), photoluminescence (PL), high resolution transmission electron microscopy (HRTEM), and radio frequency (RF). The book includes theoretical models and illustrations of characterization properties—both structural and chemical.
