The book “Theoretical electrochemistry” by the authors Alexander Leonovich Rotinyan, Konstantin Ivanovich Tikhonov and Irina Alekseevna Shoshina is a fascinating and deep immersion in the world of electrochemical processes that play a key role in modern sciences and technologies. This publication will be an indispensable assistant for both students and professionals working in the field of chemistry, physics, materials science and engineering. Electrochemistry is a science that studies the interaction of electricity and chemical reactions. In the book, the authors examine in detail the theoretical foundations of electrochemistry, explaining complex concepts in accessible language. They immerse the reader in the world of ions, electrochemical cells, and reactions that occur at the phase boundary. Each chapter is filled not only with theoretical calculations, but also with practical examples, which allows the reader to better understand how these processes are applied in real life. You will learn about such important topics as electrode processes, thermodynamics of electrochemical systems, kinetics of reactions and much more. The book will be of interest to students and graduate students studying chemistry and related disciplines, as well as teachers who are looking for high-quality and modern educational material. Specialists in electrochemistry, materials science and engineering will also find in this publication a lot of useful information that will help them in their professional activities. If you are interested in topics such as batteries, fuel cells, corrosion or electrochemical synthesis, this book will be a real find for you. One of the strengths of "Theoretical Electrochemistry" is its ability to connect theory with practice. The authors not only explain complex theoretical aspects, but also give examples from real life, which makes the material more accessible and understandable. This book will be an excellent addition to textbooks on general and physical chemistry, as well as to specialized literature on electrochemistry. The style of the authors is distinguished by clarity and logical presentation, which allows the reader to easily absorb the material. They use modern approaches to learning, including graphs, diagrams, and tables that help visualize complex concepts. This makes the book not only useful, but also fascinating to read.
