graduated in chemistry from The Hebrew University of Jerusalem (Israel), and started his work under the guidance of Prof. R. Reisfeld (M.Sc.) and Prof: D. Avnir (M.Sc. and Ph.D.), in 1982, 1984 and 1989, respectively, on the first applicatiort of the sol-gel process to the preparation of an organically doped silica gel-glass (1983). He was awarded the First Ulrich Prize in 1991, and is author of over 30 papers in sol-gel doped glasses. His current research interests include the production of liquid crystal and optically active materials by sol-gel processing and their applications. He is currently associate research officer at The Instituto de Ciencia de Materiales, Consejo Superior de Investigaciones Cientificus, CSIC, Madrid.

is Profesor Titular of Cádiz University. He received his Ph.D. degree in Physics from Seville University in 1983, for a study of the structure of amorphous semiconductors. After a postdoctoral stay at the University of Montpellier II (France), where he pioneered (with Prof. Zarzycki) the solventless preparation of gels with ultrasound, he formed a sol-gel research group at the newly founded University of Cádiz. His research interests include the characterization of gels and their application in ceramic-ceramic and semiconductor-ceramic composites processing.

The sol–gel process represents a room-temperature method of producing a wide range of ceramic materials through the formation of a glassy network by the polymerization of suitable monomers. The use of the technique to produce, for example, sonogels, organic-inorganic composites, NLO glasses, and electrooptical materials such as gel-glass dispersed liquid crystald (GDLCs) is reviewed. An example of a GDLC is shown on this issue's front cover, 4-pentyl-4-biphenylcarbonitrile in the LC state being dispersed in a thin film of silica.
