THE 2015 D.O. SHAH ANNUAL LECTURE IN SURFACE SCIENCE Presented by the Department of Chemical Engineering WHAT ARE MICROEMULSIONS GOOD FOR? KRISTER HOLMBERG RECEIVED HIS MSc DEGREE IN CHEMICAL ENGINEERING and his doctorate in organic chemistry both at Chalmers University of Technol- KRISTER HOLMBERG ogy in Gothenburg Sweden. He worked for many years in industry and he was Microemulsions are thermodynamically stable mixtures of oil, water and surfactant. To the eye, they are almost clear one-phase systems, but microscopically they contain oil and water domains separated by a monolayer of surfactant. Depending on the relative amount of oil and water and on the choice of surfactant, the structure can be oil-in-water, water-in-oil or bicontinuous. The very large oil-water interface—several orders of magnitude larger than in emulsions—make microemulsions of interest for practical use. In the talk, the use of microemulsions for four widely different applications will be described: (i) enhanced oil recovery, (ii) preparation of inorganic nanoparticles, (iii) preparative organic chemistry and (iv) cleaning of works of art.

Between 1991 and 1998 he was the Director of the Institute for Surface Chemistry in Stockholm, Sweden. He joined Chalmers as a Professor in surface chemistry in 1998. He has been Visiting Professor at the University P. et M. Curie, Paris (host: Prof. M.-P. Pileni) and at the University of Florence (host: Prof. P. Baglioni). Dr. Holmberg has published 290 journal papers and written or edited seven books. He is also the inventor of 37 patents. His current research interest covers surfactant chemistry, reactions in microemulsions and other microheterogeneous media, nanomaterials and biotechnological surface chemistry. Dr. Holmberg is Editor-in-Chief of Current Opinion in Colloid and Interface Science and he is a member of the Editorial Board of a number of other journals. He is a member of three academies: The Royal Swedish Academy of Sciences (Nobel Prize awarding academy), The Royal Swedish Academy of Engineering Sciences and The Royal Society of Arts and Sciences in Gothenburg. He is currently Chair of the latter academy. PREVIOUS SHAH LECTURERS 2005 2006 2007 2008 DARSH WASAN CURTIS FRANK BENGT KASEMO ROBERT MADIX 2009 2010 2012 2014 ROBERT K.

Shah Annual Lecture in Surface Science was established in the Chemical Engineering Department at UF by Professor Dinesh O. Shah because of his strong commitment to the university and the field of surface science. Professor Shah retired in 2005 from UF after a distinguished academic career spanning 35 years. Dinesh O. Shah received his B.S.in Physics and Mathematics from the University of Bombay, India in 1959 and his Ph.D. in Biophysics from Columbia University in 1965. He joined UF in 1970 with a joint appointment in the Chemical Engineering Department and in the Anesthesiology Department. He was appointed as the director of the Center for Surface Science & Engineering in 1984. He then served as chair of the Chemical Engineering Department at UF from 1987-1991. Dr. Shah has received numerous teaching, research and service awards, including: the UF Excellence in Teaching Award in 1972, the UF President’s Scholar Award in 1975, the UF Outstanding Service Award in 1976, the UF Teacher/Scholar of the Year Award from 1984-85 and the UF President’s Medallion for Excellence in Teaching and Scholarship in 1985. In addition, Dr. Shah was named the Florida Scientist of the Year in 1988, received the Vishwa Gurjari 1992 International Award for Outstanding Achievement and received the Pride of India Award in July 1993. In 1993, he was also named as Distinguished Florida Scientist by the Florida Academy of Sciences. In 1996, he was honored with the first Charles A. Stokes Professorship at UF. He has been the founding director of the Shah-Schulman Center for Surface Science and Nanotechnology, D.D. University, Nadiad, lndia since January 2008.
