Carlos Alberto Martinez Huitle graduated in Chemistry at Universidad de las Américas-Puebla (México) under supervision of Prof. Dr. Marco Antonio Quiroz Alfaro. After a work experience in Ciba—Specialty Chemicals (currently acquired by the German chemical company BASF), he moved to Ferrara (Italy) where he received his PhD in Chemical Sciences at the University of Ferrara under supervision of Prof. Achille De Battisti. During the same period, he worked as visiting scientist in the group of Prof. Christos Comninellis at the EPFL Institute, Switzerland. From since 2005 to 2008, he has served as faculty member in the Department of Chemistry at the University of Milan. In 2008, he also moved to Brazil where he currently is an Associate Professor in the Institute of Chemistry at the Federal University of Rio Grande do Norte. Manuel A Rodrigo obtained his PhD degree in the University of Valencia in 1997, with a research focused on the modelling and automation of biological nutrient removal processes. In 1997, he joined the University the Castilla La Mancha and began researching on electrochemical engineering. In this first postdoctoral stage, his research was focused on the electrolyses of industrial wastewater. After a first postdoctoral training in the Lab of Prof. Comninellis (EPFL, Switzerland), he started working with diamond electrodes, one of the key topics in his research. In 2000, he was appointed as Associate Professor at the University of Castilla La Mancha, and began researching on electrocoagulation and high temperature PEM fuel cells. Onofrio Scialdone studied Chemical Engineering at the University of Palermo. He obtained his PhD degree in Electrochemical Engineering in the Politecnico di Milano in 1999 and a Master in Economy at the Scuola Mattei of ENI (2000). He is Professor of Industrial Chemistry at Università degli Studi di Palermo and he leads the research activities on electrochemistry of the “Laboratory of Chemical and Electrochemical Technologies at the same University. His main research interests are in electrochemical reaction engineering, with particular emphasis on synthesis of fine chemicals, environmental protection and electrical energy generation
