Preface

We are pleased to introduce volume 15 of Specialist Periodical Reports in Electrochemistry, which presents comprehensive and critical reviews covering some of the most impactful areas of electrochemistry. In this volume, Randavir discusses electrochemical impedance spectroscopy as a quantitative tool for sensors for a wide variety of potential applications. Baranova and co-authors provide a comprehensive and critical discussion around our current state-of-the-art understanding of ethanol electrooxidation kinetics in alkaline media. They point to the excellent progress made to date, and the challenges remaining, as we move towards high performance direct ethanol fuel cells. Dennany contributes an extensive discussion of electrochemiluminescence sensors, from their fundamental principles to their application in analytic systems, particularly for medical diagnostics. The chapter discusses the development of the most commonly utilized ruthenium base systems, emerging new materials, and their incorporation in composite nanomaterials. Wearable electrochemical sensors are discussed in a chapter by Mohamed, with consideration of sensors that monitor sweat, breath, saliva, tears and skin to monitor our health and provide diagnostic signals. Finally, Adarakatti and Kempahanumakkagari consider techniques for electrode modification to enhance both kinetics and stability, and the characterization and application of the electrodes in electro-analysis.
