electromotive force in chemistry: Electrochemistry at Metal and Semiconductor Electrodes Norio Sato, 1998-10-09 Electrochemisty at Metal and Semiconductor Electrodes covers the structure of the electrical double layer and charge transfer reactions across the electrode/electrolyte interface. The purpose of the book is to integrate modern electrochemistry and semiconductor physics, thereby, providing a quantitative basis for understanding electrochemistry at metal and semiconductor electrodes. Electrons and ions are the principal particles which play the main role in electrochemistry. This text, therefore, emphasizes the energy level concepts of electrons and ions rather than the phenomenological thermodynamic and kinetic concepts on which most of the classical electrochemistry texts are based. This rationalization of the phenomenological concepts in terms of the physics of semiconductors should enable readers to develop more atomistic and quantitative insights into processes that occur at electrodes. The book incorporates many traditional disciplines of science and engineering such as interfacial chemistry, biochemistry, enzyme chemistry, membrane chemistry, metallurgy, modification of solid interfaces, and materials' corrosion. The text is intended to serve as an introduction for the study of advanced electrochemistry at electrodes and is aimed towards graduates and senior undergraduates studying materials and interfacial chemistry or those beginning research work in the field of electrochemistry. |
electromotive force in chemistry: University Physics Samuel J. Ling, Jeff Sanny, William Moebs, 2017-12-19 University Physics is designed for the two- or three-semester calculus-based physics course. The text has been developed to meet the scope and sequence of most university physics courses and provides a foundation for a career in mathematics, science, or engineering. The book provides an important opportunity for students to learn the core concepts of physics and understand how those concepts apply to their lives and to the world around them. Due to the comprehensive nature of the material, we are offering the book in three volumes for flexibility and efficiency. Coverage and Scope Our University Physics textbook adheres to the scope and sequence of most two- and three-semester physics courses nationwide. We have worked to make physics interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. With this objective in mind, the content of this textbook has been developed and arranged to provide a logical progression from fundamental to more advanced concepts, building upon what students have already learned and emphasizing connections between topics and between theory and applications. The goal of each section is to enable students not just to recognize concepts, but to work with them in ways that will be useful in later courses and future careers. The organization and pedagogical features were developed and vetted with feedback from science educators dedicated to the project.

electromotive force in chemistry: Electrochemistry and Corrosion Science Nestor Perez, 2007-05-08 Electrochemistry and Corrosion Science is a graduate level text/professional reference that describes the types of corrosion on metallic materials. The focus will be on modeling and engineering approximation schemes that describe the thermodynamics and kinetics of electrochemical systems. The principles of corrosion behavior and metal recovery are succinctly described with the aid of pictures, figures, graphs and schematic models, followed by derivation of equations to quantify relevant parameters. Example problems are included to illustrate the application of electrochemical concepts and mathematics for solving complex corrosion problems. This book differs from others in that the subject matter is organized around the modeling and predicating approaches that are used to determine detrimental and beneficial electrochemical events. Thus, this book will take a more practical approach and make it especially useful as a basic text and reference for professional engineers. |

electromotive force in chemistry: Electromotive Forces Aiden Hopkins, 2018-01-10 The word e;forcee; in this case is not used to mean mechanical force, measured in newtons, but a potential, or energy per unit of charge, measured in volts. In electromagnetic induction, Electro-Motive force (emf) can be defined around a closed loop as the electromagnetic work that would be done on a charge, if it travels once around that loop. For a time-varying magnetic flux linking a loop, the electric potential scalar field is not defined due to circulating electric vector field, but nevertheless an emf does work, that can be measured as a virtual electric potential around that loop. The electromotive force EMF of a source of electric potential energy is defined as the amount of electric energy per Coulomb of positive charge as the charge passes through the source from low potential to high potential. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. Author believes that this book is important enough to be preserved, reproduced, and made generally available to the public.
