Spectroscopic Tools for Food Analysis


Book Description

Food quality analysis is an area of interest that has always attracted the attention of everyone, and making suitable tools for food analysis is especially important. This volume presents such techniques and their state-of-the-art applications. It covers different spectroscopic methods spread over the wide range of electromagnetic spectrum that are being applied in food analysis. Detection of ammonia nitrogen using spectroscopic process is also included as it is the source of protein synthesis in aquatic plants and animals, which serve as an important ingredient of our diet. Individual chapters cover recent trends and applications of a particular technique in different areas of food analysis. This book also includes comparison of different approaches wherever necessary in view of actual applications. Mathematical details have been kept to a necessary minimum as far as possible, keeping in mind the novice researchers and technicians. Furthermore, an interdisciplinary character is naturally a distinctive feature throughout as contributors are from different disciplines including science, engineering and pharmacy.




Electrochemical Impedance Spectroscopy


Book Description

Using electrochemical impedance spectroscopy in a broad range of applications This book provides the background and training suitable for application of impedance spectroscopy to varied applications, such as corrosion, biomedical devices, semiconductors and solid-state devices, sensors, batteries, fuel cells, electrochemical capacitors, dielectric measurements, coatings, electrochromic materials, analytical chemistry, and imaging. The emphasis is on generally applicable fundamentals rather than on detailed treatment of applications. With numerous illustrative examples showing how these principles are applied to common impedance problems, Electrochemical Impedance Spectroscopy is ideal either for course study or for independent self-study, covering: Essential background, including complex variables, differential equations, statistics, electrical circuits, electrochemistry, and instrumentation Experimental techniques, including methods used to measure impedance and other transfer functions Process models, demonstrating how deterministic models of impedance response can be developed from physical and kinetic descriptions Interpretation strategies, describing methods of interpretating of impedance data, ranging from graphical methods to complex nonlinear regression Error structure, providing a conceptual understanding of stochastic, bias, and fitting errors in frequency-domain measurements An overview that provides a philosophy for electrochemical impedance spectroscopy that integrates experimental observation, model development, and error analysis This is an excellent textbook for graduate students in electrochemistry, materials science, and chemical engineering. It's also a great self-study guide and reference for scientists and engineers who work with electrochemistry, corrosion, and electrochemical technology, including those in the biomedical field, and for users and vendors of impedance-measuring instrumentation.




An Introduction to Electrochemical Impedance Spectroscopy


Book Description

This book covers the fundamental aspects and the application of electrochemical impedance spectroscopy (EIS), with emphasis on a step-by-step procedure for mechanistic analysis of data. It enables the reader to learn the EIS technique, correctly acquire data from a system of interest, and effectively interpret the same. Detailed illustrations of how to validate the impedance spectra, use equivalent circuit analysis, and identify the reaction mechanism from the impedance spectra are given, supported by derivations and examples. MATLAB® programs for generating EIS data under various conditions are provided along with free online video lectures to enable easier learning. Features: Covers experimental details and nuances, data validation method, and two types of analysis – using circuit analogy and mechanistic analysis Details observations such as inductive loops and negative resistances Includes a dedicated chapter on an emerging technique (Nonlinear EIS), including code in the supplementary material illustrating simulations Discusses diffusion, constant phase element, porous electrodes, and films Contains exercise problems, MATLAB codes, PPT slide, and illustrative examples This book is aimed at senior undergraduates and advanced graduates in chemical engineering, analytical chemistry, electrochemistry, and spectroscopy.




Nonaqueous Electrochemistry


Book Description

An examination of applications of electrochemical techniques to many organic and inorganic compounds that are either unstable or insoluble in water. It focuses on the continuing drive toward miniaturization in electronics met by designs for high-energy density batteries (based on nonaqueous systems). It addresses applications to nonaqueous batteries, supercapacitators, highly sensitive reagents, and electroorganic and electroinorganic synthesis.




Developments in Electrochemistry


Book Description

Martin Fleischmann was truly one of the ‘fathers’ of modern electrochemistry having made major contributions to diverse topics within electrochemical science and technology. These include the theory and practice of voltammetry and in situ spectroscopic techniques, instrumentation, electrochemical phase formation, corrosion, electrochemical engineering, electrosynthesis and cold fusion. While intended to honour the memory of Martin Fleischmann, Developments in Electrochemistry is neither a biography nor a history of his contributions. Rather, the book is a series of critical reviews of topics in electrochemical science associated with Martin Fleischmann but remaining important today. The authors are all scientists with outstanding international reputations who have made their own contribution to their topic; most have also worked with Martin Fleischmann and benefitted from his guidance. Each of the 19 chapters within this volume begin with an outline of Martin Fleischmann’s contribution to the topic, followed by examples of research, established applications and prospects for future developments. The book is of interest to both students and experienced workers in universities and industry who are active in developing electrochemical science.

Electrochemical Impedance


Book Description

The collection of twenty-seven papers published has been grouped into six major categories : corrosion process characterization and modeling, applications of Kramers-Kronig transformations for evaluating the validity of data, corrosion and its inhibition by either corrosion products of specially added inhibitors, corrosion of aluminum and aluminum alloys, corrosion of steel in soils and concrete, and evaluation of coatings on metal substrates.




New Trends in Electrochemical Impedance Spectroscopy (EIS) and Electrochemical Noise Analysis (ENA)


Book Description

These 22 contributions concentrate primarily on newer applications of the staple EIS technique, and secondarily, on the more recent use of ENA in corrosion research. Papers treat experimental aspects of EIS and data analysis; EIS for investigating the protective properties and degradation of polymer coatings; and EIS in combination with other techniques to study specific corrosion phenomena, e.g., the corrosive rates of steel in soil environments. Mansfeld (U. of Southern California), et al., describe the use of both techniques to monitor the corrosion behavior of active and passive systems exposed to chloride media. The volume includes facts about the Electrochemical Society. Annotation copyrighted by Book News Inc., Portland, OR.
