Henri Groult is Director of Research of CNRS-UPMC-ESPCI UMR 7612, University of Pierre and Marie Curie (Paris 6) in France. He has devoted his research life to fluorine chemistry, electrochemistry, and molten salt chemistry. His main research subjects are electrolytic production of fluorine gas, fluorine compounds for primary and secondary lithium batteries, and electrochemical properties of molten fluorides and chlorides. He has obtained interesting results on fluorine evolution reaction on carbon electrodes, discharge behavior of carbon-fluorine compounds, charge/discharge characteristics of metal fluorides, and electrochemical properties of molten salts. On these subjects, he published more than 100 papers and 7 books. His activity has played an important role in fluorine chemistry in France. He has served as Director of the French Network of Fluorine, Chairman of the 17th European Symposium on Fluorine Chemistry (Paris, July 2013), and Editorial board of J. Fluorine Chemistry. Frederic Leroux is CNRS Research Director at the University of Strasbourg. He is Director of the joint CNRS-Bayer laboratory of organofluorine chemistry and director of the molecular chemistry department (UMR CNRS 7042-LIMA) at the European School of Chemistry, Polymers and Material Sciences (ECPM). His research is published in >110 peer-reviewed papers, 18 patents, 8 book chapters and presented by invitation at >100 (inter)national conferences. He is Fellow of the Royal Society of Chemistry (FRSC) and member of the European Academy of Sciences and Arts. He is also a member of the International Scientific Committee of the Moissan Prize (Fluorine Chemistry) and Director of the French Fluorine Network. His scientific interest covers various fields, based on a fruitful interplay of several objectives (a) the synthesis of biologically relevant molecules, (b) asymmetric methodologies using organic and organometallic chemistry, (c) organofluorine chemistry and (d) application of the objectives to industrial problems, which led to strong industrial collaborations. Alain Tressaud is Emeritus Research Director at ICMCB-CNRS, Bordeaux University. He is President of the European Academy of Science in Brussels and member of several European academies. He founded and chaired the French Network on Fluorine Chemistry, sponsored by CNRS, until 2008. He has received several awards, including the CEA Award of French Academy of Sciences (2008), the Fluorine Award of the American Chemical Society (2011), and the International Henri Moissan Prize (2013). His scientific interest covers various fields, including synthesis, physical chemical characterizations, applications in fluorine chemistry, solid state chemistry, and materials sciences. His work also deals with surface modification of materials and intercalation chemistry. Professor Tressaud’s scientific production includes more than 360 papers in international journals, 20 book chapter contributions, and 12 internationalized patents. He has also edited several books in his role as editor-in-chief of the series “Advances in Fluorine Science” (2006) and “Progress in Fluorine Science” (2016) with Elsevier.
