David Levy is a Research Professor and head of the Sol-Gel Group at the Materials Science Institute of Madrid (ICMM) of the Consejo Superior de Investigaciones Cientí cas. His research interests are optical materials (bulk materials; thin- lm coatings as AR optical coatings, protection transparent coatings and functional coatings; oxide nanoparticles) and liquid crystal materials, by Sol-Gel processing and their applications. During his time at The Hebrew University of Jerusalem David Levy pioneered the sol-gel process for the preparation of organically doped silica-gel glasses. He has more than 130 publications and a number of patents to his name, and has received numerous prizes in recognition of his groundbreaking work on sol-gel materials, including the ?First Ulrich Prize? and the nomination to King Juan Carlos-I research award. Marcos Zayat is currently vice-director of the Materials Science Institute of Madrid (ICMM). His scienti c interests are centered on the design of new optical coatings and the characterization of their physicochemical properties. After having obtained his Ph D in Materials Science from The Hebrew University of Jerusalem in 1997, Marcos Zayat joined the ICMM where he continues developing sol-gel materials for optical and electrooptical applications. He has published more than fty original articles in prestigious scienti c journals.
