This volume in the 'Advances in Electrochemical Sciences and Engineering’ series focuses on problem-solving, illustrating how to translate basic science into engineering solutions.
The book’s concept is to bring together engineering solutions across the range of nano-bio-photo-micro applications, with each chapter co-authored by an academic and an industrial expert whose collaboration led to reusable methods that are relevant beyond their initial use.
Examples of experimental and/or computational methods are used throughout to facilitate the task of moving atomistic-scale discoveries and understanding toward well-engineered products and processes based on electrochemical phenomena.

He has received numerous prizes, including Vittorio de Nora Award and Lifetime National Associate award from National Academy.
Philip N. Bartlett is Head of the Electrochemistry Section, Deputy Head of Chemistry for Strategy, and Associate Dean for Enterprise in the Faculty of Natural and Environmental Sciences at the University of Southampton. He received his Ph D from Imperial College London and was a Lecturer at the University of Warwick and a Professor for Physical Chemistry at the University of Bath, before moving to his current position. His research interests include bioelectrochemistry, nanostructured materials, and chemical sensors.
Marc Koper studied chemistry at Utrecht University and obtained his Ph D (cum laude) with Prof. J.H. Sluyters from Utrecht University. He was a postdoctoral Marie Curie Fellow in the group of Prof. W. Schmickler at the University of Ulm (Germany). He then returned to the Netherlands to join the group of Prof. R.A. van Santen at Eindhoven University of Technology, where he initially was a Fellow of the Royal Netherlands Academy of Arts and Sciences and later associate professor. In 2005 he was appointed full professor in fundamental surface science at Leiden University.
