> Oxidation-reduction (redox) reactions are among the most important and interesting chemi‐ cal reactions that occur in life forms including respiration and metabolism; aquatic systems including soils, sediments, aquifers, rivers, lakes, and water treatment systems; atmospheric processes including ozone-oxygen reverse reaction; many industrial processes; and electro‐ chemical processes. Redox reactions are central to the major element cycling, many cell cy‐ cles, many chemisorption and physisorption processes, trace element mobility from rocks and sediments toward wells, aquifers, trace element toxicity toward life forms, and most remediation schemes including water treatments; over the last three decades, the field has attracted a lot of scientists, and a great deal of researches has been done in redox chemistry, but the field is only beginning to converge around a unified body of knowledge.

> This book provides a very broad overview of the state of the art of understanding redox process. The book starts with giving a concise introduction that describes the origin, histori‐ cal background, and the development of the redox definitions. The book is organized into two sections that include ten chapters and introduces, in Section 1, generalized electron bal‐ ance theory and its applications in electrolytic redox systems, redox-active molecules and its applications in device memory, fundamentals and applications of flow batteries and its inte‐ gration into antidirect current, and donor acceptor titrations of displacement and electronic transference. Section 2 introduces redox in biological processes, including roles of reactive oxygen species in respiration, metabolism, and regulations, and redox in physiological proc‐ esses as redox-sensitive TRP channels TRPA1 and TRPM2. All chapters are written by differ‐ ent authors (with the exception of Chapter 1 [Introduction]). This clearly reflects the broad range of topics that have been covered by experts in the field.

> The book is primarily aimed at an academic audience but will also be useful for a wide range of professionals at different career stages from master"s students to any scientist who wants to investigate and understand the electrochemical and coupled properties of electro‐ active materials.

> I thank all the chapter authors for their contributions to the book and the book processing manager Nina Kalinic for her valuable comments and assistance in the preparation of the book for publication. I hope that readers with an interest in redox will find the book interest‐ ing and of value for their own research.
