Angelo Basile is a senior researcher at the Institute on Membrane Technology (ITM) of the Italian National Research Council (CNR). His research is focussed onultra-pure hydrogen production and CO2 capture using inorganic membrane reactors as well as on the polymeric membranes (preparation and characterization) to be used for gas separation. Angelo has published more than 100 papers in the field of membrane technology, has written over 50 book chapters and edited or co-edited 8 books. He is also Associate Editor for the International Journal of Hydrogen Energy for Elsevier. Catherine Charcosset is Research Director at the Laboratoire d'Automatique et de G nie des Proc d s, part of the CNRS (Centre National de la Recherche Scientifique), based at the University of Lyon, France. Her research includes work on the characterization of membranes by confocal microscopy, ultrafiltration and microfiltration, membrane chromatography, preparation of emulsions and particles, and membrane crystallization for biotechnological, pharmaceutical and environmental applications. Catherine has published extensively in these fields especially filtration and membrane chromatography, both as articles and book chapters.
