FOREWORD


The A D V A N C E S I N C H E M I S T R Y S E R I E S was founded in 1949 by the American

Chemical Society as an outlet for symposia and collections of data i n special areas of topical interest that could not be accommodated in the Society s journals. It provides a medium for symposia that would otherwise be fragmented because their papers would be distributed among several journals or not published at all. Papers are reviewed critically according to A C S editorial standards and receive the careful attention and processing characteristic of ACS publications. Volumes in the A D V A N C E S I N C H E M I S T R Y S E R I E S maintain the integrity of the symposia on which they are based; however, verbatim reproductions of previously published papers are not accepted. Papers may include reports of research as well as reviews, because symposia may embrace both types of presentation.



ABOUT T H E EDITOR H O R A C I O E. B E R G N A is a Senior Research Associate at the DuPont Experimental Station. H e first joined DuPont in 1956 as part of Ralph K. Her s research group. Bergna received his Licenciado and doctorate in chemistry at the National University of L a Plata in Argentina and worked on his doctoral thesis (Honors) on clay electrokinetics under Marcos Tschapek at the National Institute of Soils i n Buenos Aires, Argentina. Bergna taught at the School of Chemistry in L a Plata and worked at L.E.M.I.T. (Technological Research Laboratory of the Province of Buenos Aires). H e did post-doctoral work at the Sorbonne in Paris and the Massachusetts Institute of Technology, where he worked with E . A. Hauser as a Guest of the Department of Chemical Engineering and as a Research Staff Member of the Division of Industrial Cooperation with J. Th. Overbeek, A. Gaudin, and P. de Bruyn. H e studied humanities at the City of London College and Columbia University. Bergna is the author of 30 papers and holds 31 U.S. patents and more than 200 foreign corresponding patents in subjects such as colloidal silica synthesis; silica; alumina; aluminosilicates; zeolites; vanadyl phosphate catalysts; submicron grained products for metallurgy; coated particulates for ceramics, electronics, chromatography, and polymers; and binders for foundry sands. In 1989 he was appointed Chevalier of the Ordre Des Palmes Académiques by the French government. Bergna is a retired president of the Alliance Française de Wilmington, Delaware, and a founder and chairman of the board of the Fondation Internationale de Delaware. In 1990 he organized and chaired the Ralph K. Her International Symposium on the Colloid Chemistry of Silica held at the 200th A C S National Meeting. Bergna co-authored the Colloidal Silica Section of the 1993 edition of the Ullmann Encyclopedia of Chemistry and guest edited two special issues of the Elsevier international journal Colloids and Surfaces.
