Purdue University School of Chemical Engineering Graduate seminar series Prof. Horia Metiu University of California, Santa Barbara "Catalytic Alkane Activation: Theory and Experiments" November 4, 2014 9:00-10:15 a.m. FRNY G140 Reception at 10:15-10:45 a.m. in Henson Atrium Abstract: I will present our work on two topics: 1. The use of density functional computations to explore whether we can improve catalytic activity of oxides, for alkane activation, by various chemical modifications. 2. Experiments that study halogen mediated oxidative dehydrogenation of propane to produce propylene. Within the first topic we use as a guide the observation that when co-adsorbed a Lewis base and a Lewis acid interact strongly through the oxide. This allows us to predict qualitative trends regarding the ability of various kinds of doped oxide surfaces to break the carbon-hydrogen bond in alkanes. In the second topic I present experiments that show that iodine or bromine mediated oxidative dehydrogenation is very effective in converting propane to propylene. We show that this takes place when the gaseous halogen is introduced in a mixture of propane and oxygen or when it is produced by the action of oxygen on molten LiI or LiBr. Bio: M.S. degree in Chemical Engineering from the Polytechnic Institute Bucharest and PhD in theoretical chemical physics from MIT with John Ross and Robert Silbey. He was a postdoc at the University of Chicago with Karl Freed. He has been professor at the University of California in Santa Barbara since 1976. Worked in many areas of theoretical chemical physics: surface enhanced spectroscopy, time-domain theory of spectroscopy, theory of rate constants, femtochemistry, crystal growth and epitaxy, thermoelectrics, catalysis and surface science. From time to time he did experimental work in collaboration with colleagues. He developed metastable quenching spectroscopy of adsorbates (with Yates and Martin), worked on fuel cell membranes (with Buratto), thermoelectric materials (with Stucky), the surface science of mass selected supported oxide or metal clusters (with Bowers and Buratto) and catalysis (with McFarland and Gordon). Currently his focus is on computations and experiments on catalysis and he is writing (slowly) a book on quantum mechanics.

Dr. Zhen-Gang Wang Announcement

Purdue University School of Chemical Engineering Graduate seminar series Prof. Zhen-Gang Wang Full Professor California Institute of Technology "Self-Energy Effects of Salt Ions on Phase Behavior and Interfacial Properties" October 21, 2014 9:00-10:15 a.m. FRNY G140 Reception at 10:15-10:45 a.m. in Henson Atrium Abstract: Ions are essential in physical chemistry, colloidal science, electrochemistry, biology and many other areas of science and engineering. While their role is commonly described in terms of screening and translational entropy, many phenomena, ranging from some classical experimental observations made many decades ago to some new systems of current interest, cannot be explained, even qualitatively, by these concepts. A key effect that is often ignored or inadequately treated in the main literature on electrolytes and polyelectrolytes is the self-energy of the ions. In this talk, I will discuss several self-energy effects in macromolecular and interfacial systems. First, we show that the preferential solvation energy of the ions provides a significant driving force for phase separation. This concept is used to develop a theory to explain the dramatic shift in the order-disorder transition temperature in PEO-PS diblock copolymers upon the addition of salt. Second, we show that the dielectric contrast between the polymer backbone and the solvent significantly affects the conformation and charge condensation in dilute polyelectrolyte solutions. Third, we show that the image force has qualitative effects on the double layer structure and forces, such as like charge attraction and charge inversion. Finally we present a simple model for understanding the specific ion effects in the interfacial activity for air/water and oil/water interfaces. Bio: Zhen-Gang Wang received his bachelor's degree in Chemistry from Beijing (Peking) University in 1982, and his Ph. D in Chemistry from the University of Chicago where he worked with Stuart Rice and Karl Freed. He then worked as a postdoctoral fellow first in Exxon Research and Engineering Company, with Sam Safran and Tom Witten, and then at UCLA with Bill Gelbart. In 1991, he joined the Chemical Engineering faculty at Caltech, was promoted to Associate Professor in 1997 and became Full Professor in 2002. Zhen-Gang Wang's research is the theoretical and computational study of structures, phase behavior, interfacial properties and dynamics of polymers, soft materials, and biophysical systems. His current activities revolve around three main themes: charged systems, nucleation or more generally barrier crossing, and nonlinear rheology of polymers gels and entangled polymers.
