About the book

Electrochemical impedance spectroscopy (EIS) is a complex analytical technique that is basically used to characterize electrochemical systems. As a non-destructive approach, EIS serves to inaugurate the electrical response over an array of frequencies using an alternating current (AC). In other words, and for the system under investigation, a perturbation (either constant or variable) is being introduced using a potential with a small amplitude, and accordingly, the instrument recognizes and translates the ensuing changes as an impedance diagram. The generated data are a bit complex and need careful analysis.

As an analytical technique with realms of applications, EIS has seen major progress during the past few years. One reason could be the feasibility of implementing EIS in a system, and the other would be the usefulness of EIS data in determining properties such as reaction rate, as well as the diffusion coefficients. Applications of EIS varied between corrosion analysis and inhibition, food and drug analysis, monitoring the performance of batteries, and developing biosensors, etc. Impedance microbiology which is used to monitor bacterial growth in a sample, and tissue electrical impedance which is basically used for detecting abnormalities in morphology and health of tissues, are other examples for the applications of EIS.

Introducing your Author Service Manager

Mr. Gordan Tot

As an Author Service Manager my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review, to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
