Eli Ruckenstein

State University of New York at Buffalo, USA

Eli Ruckenstein, a Distinguished Professor of chemical engineering at the State University of New York at Buffalo, received all of his degrees from Polytechnic University of Bucharest, Romania, and was a Professor there from 1949 to 1969. In 1969, he was invited by the National Science Foundation as a Senior Scientist at Clarkson University. He served as a Professor at the University of Delaware from 1970 to 1973 before joining the faculty of Buffalo. Professor Ruckenstein’s research interests have covered most aspects of chemical engineering, including transport phenomena, catalysis, surface phenomena, colloids, emulsions, separation processes, and biocompatible surfaces and materials. He is a Member of the National Academy of Engineering and received the National Medal of Science in 1998. Ruckenstein has broken new paths in the areas of transport phenomena in usual fluids and in colloidal dispersions, in the stability of nanosize liquid and solid films, in thermodynamics of complex fluids. He pioneered the theoretical treatment of the sintering and redispersion of supported metal catalysts, developed the first kinetic theory of nucleation, and explained the restabilization of colloidal dispersions at high ionic strengths and the occurrence of Newton black films in foams. He developed new technologies for the preparation of polymers, membranes, some catalytic processes and protein separation. He opened a new chapter in catalysis through his theories and experiments regarding the changes that occur in the catalyst through sintering, redispersion, and spreading. He proposed the first quantum explanation of the poisoning and promoting of catalysts. He initiated the modern thermodynamics of dispersions and applied it to microemulsions, lamellar liquid crystals, and surfactants at interfaces. He developed theories for hydration forces and hydrophobic forces and proposed the first predictive theory of micellization.
