Donna Blackmond, 2001 Emmett Award.

The Paul H. Emmett Award in Fundamental Catalysis, sponsored by the Davison Chemical Division of W.R. Grace and Company and administered by The North American Catalysis Society, is given to recognize and encourage individual contributions in the field of catalysis with emphasis on discovery and understanding of catalytic phenomena, proposal of catalytic reaction mechanisms and identification of and description of catalytic sites and species. This year the recipient is Donna G. Blackmond of the University of Hull, UK. Prof. Blackmond's major contribution has been the demostration of the importance of kinetic influences on enantioselectivity in asymmetric catalytic reactions. Particulary noteworthy is her detailed analysis of the kinetic contributions to nonlinear effects of catalyst enantiopurity on enantioselectivity. This work is quantitative support to observation by Prof. Noyori that kinetics is the "fourth dimension" of asymmetric catalysis, taken in conjunction with stereochemical considerations in these reactions. This work has had wide impact in both heterogeneous and homogeneous catalysis at both the mechanistic and practical levels. Prof. Blackmond has shown a particular talent in making important connections in her research. Her work has helped to show relationships between heterogeneous and homogeneous catalysis and links between fundamental and applied research. Her accomplishments working in both academic and indusrtial research environments reflect an interest and understanding of the broad scope of research in catalytic technology in the emerging area of pharmaceuticals and fine chemicals.

Leo Manzer, 2001 Houdry Award.

The Eugene J. Houdry Award in Applied Catalysis, sponsored by Sűd-Chemie, Inc and administered by The North American Catalysis Society, is given to recognize and encourage individual contributions in the field of catalysis with emphasis on the development of new and improved catalysts and processes representing outstanding advances in their useful application. This year the recipient is Leo E. Manzer of the DuPont Co. Leo is highly regarded in the catalysis community and has contributed greatly to the promotion of catalysis within DuPont and iternationally. He has received several prestigious awards, including the 1995 ACS Earle Barnes Award for Creative Leadership in R&D Management, the 1997 Philadelphia Catalysis Club Award and the 1998 Cross-Canada Lecture Tour Award. He has over 60 issued or allowed US patents, over 80 publications and has delivered more than 130 invited lectures in over 25 countries. During his 27 years with DuPont, Leo has been actively involved in catalysis research, catalysis management and the commercial development of catalytic processes, resulting in hundreds of millions of dollars of revenue to DuPont. His most significant achievement in DuPont was to form the Corporate Catalysis Center in 1987, when catalysis was at a low point in industry and the country. He directed this Center until 1995 and had a staff of over 165 Ph.D. scientists and engineers at its peak. The Catalysis Center had a major financial impact for DuPont. The most widely recognized effort was the development of ozone-friendly replacement for chlorofluorocarbons (CFC's). More recently he was coinventer of new catalysts for the production of phosgene from CO/Cl2 that produce very low levels of the ozone depleting byproduct, CCl4, thereby solving a significant environmental issue at a New Jersy plant. Leo and his team received the 1997 ACS Heroes of Chemistry award and the two DuPont Awards for Engineering Excellence and Safety, Health and Environment in 1997 for this work.

Tobin Marks, 2001 Burwell Lectureship.

The Robert Burwell Lectureship in Catalysis is sponsored and administered by The North American Catalysis Society. The award is given in recognition of substantial contribution to one or more areas in the field of catalysis with emphasis on discovery and undestanding of catalytic phenomena, catalytic reaction mechanisms and identification and description of catalytic sites and species. This year the recipient is Tobin J. Marks of Northwestern University. In a relatively short but remarkably productive career, Tobin Marks has demonstrated exceptional originality, breadth, and insight. His research has had a major impact on contemporery catalytic science with seminal work on organo-f-element homogeneous catalysis, metallocene polymerization, metal-ligand bonding energetics, and supported organometallic catalysts being the centerpieces. Tobin's style embodies discriminating choice of problem, elegant chemical synthesis, incisive elucidation of reaction mechanism, and decisive application of an awesome array of physical techniques. His published results are scholary investigations of the highest quality, meticulously researched, and presented with great clarity. For 1981-1997, Tobin was the second most cited catalytic chemist and the second most cited inorganic chemist worldwide. In September he was named Vladimir N. Ipatieff Professor at Northwestern after a worldwide search and recently was awarded the ACS Award in the Chemistry of Materials. Tobin's dedication is tempered with civility, genuine concern for the welfare of students and colleagues, and unflagging attention to the progress of our discipline. For example, Tobin has thrown tremendous energy into organizing NSF, DOE, and NRC workshops on problems related to catalysis, two NATO Institutes, a Gordon Conference, and ACS symposia. He has served tirelessly as Associate Editor of Organometallics, and recently as chair of the ACS division of Inorganic Chemistry. Tobin has also served on numerous governmental and industrial advisory committees and has mentored over 65 Ph.D. students and nearly as many postdoctoral fellows. They hold academic, industrial, and government positions worldwide. Professor Marks may be invited by the local Clubs and Societies to visit and lecture: Professor Tobin J.

Ipatieff Prize

JOAN F. BRENNECKE, professor of chemical engineering at the University of Notre Dame, says her primary motivation for pursuing a career in chemical engineering was her father, who is also a Ph.D. chemical engineer, although now retired.

Born in 1962, Brennecke graduated with a degree in chemical engineering from the University of Texas, Austin, in 1984. She then became a graduate student at the University of Illinois, Urba-na-Champaign, where she carried out research on supercritical fluids using fluorescence spectroscopy and obtained a Ph.D. degree in 1989. Her adviser was chemical engineering professor Charles A. Eckert, a former recipient of the Ipatieff Prize.

After completing a Ph.D., she expanded her research on supercritical fluids at the University of Notre Dame, where she included studies of reaction kinetics, first as assistant professor and then as associate professor. She was appointed professor of chemical engineering at the university in 1998.

Brennecke's current research interests embrace supercritical fluid technology, solvent effects on reactions in supercritical fluids, phase equilibria under extreme conditions, environmentally benign chemical processing, and the physical properties of carbon dioxide/ionic liquid mixtures.

Brennecke has published roughly 70 research papers and review articles and has received several awards for her research and teaching. She is also an editorial advisory board member of Industrial & Engineering Chemistry Research and the Journal of Chemical & Engineering Data.

The award address will be presented before the Division of Industrial & Engineering Chemistry.

ACS Award in Colloid or Surface Chemistry

Sponsored by Procter & Gamble Co.

"I always wanted to be a golf pro," says CHARLES T. CAMPBELL, looking back on his teen years. Having grown up in a household with professional golfers for his father and brother, the University of Washington, Seattle, chemistry professor's youthful aspiration isn't surprising. But excellent grades in science and math and the recognition that success as a golf pro requires lots of luck-not just skill-helped steer Campbell away from sports and into a life of science.

As a scientific researcher, Campbell has focused on elucidating reaction mechanisms in heterogeneous catalysis. By applying surface analysis techniques and other methods, he has answered key questions about CO oxidation, ethylene epoxidation, and dehydrogenation of hydrocarbons on platinum.

Campbell and his Seattle group are credited with clarifying structure-function relationships central to copper-zinc oxide catalysts used in methanol synthesis and the water gas-shift reaction.

Campbell's investigations have uncovered the roles of catalytic promoters and poisons, and he has contributed to a fundamental understanding of bimetallic surfaces. As one colleague put it, "Camp-bell's strength is his ability to meld surface analysis and catalytic sciences into a single discipline."

Surface scientists point out that some of Campbell's most noteworthy contributions come in the area of single-crystal microcalorimetry. Just a few years ago, Campbell and coworkers built a unique instrument that can be used to measure the heat of adsorption of metals on well-characterized specimens as a detailed function of surface coverage (C&EN, Jan. 19,1998, page 39). The technique also allows researchers to extract adhesion energies of metal films on solid surfaces. This type of information is crucial to understanding materials issues in catalysis, microelectronics, and other areas.

Microcalorimetry offers clear advantages over other techniques. For years, researchers had attempted to get a handle on adsorption energies using thermal-desorption spectroscopy or other methods, but those procedures suffered shortcomings in that they only worked on completely reversible systems. Many molecules dissociate or react before desorbing, and therefore their bond energies cannot be probed by those methods.

More recently, Campbell has begun studying surface functionalization. He and his students have investigated organosilanes bonded to titanium dioxide and biological layers on gold. The group has developed new methods for quantitative surface-plasmon-resonance sensing and has applied them to investigate protein binding to surface-immobilized ligands.

Campbell studied at the undergraduate and graduate levels at the University of Texas, Austin. In 1975, he received a B.S. degree in chemical engineering, and in 1979 he received a Ph.D. in physical chemistry for research conducted under the direction of chemistry professor J.M. White.

After completing his graduate education, Campbell continued studying catalytic surfaces as a postdoctoral research associate with Gerhard Ertl, a noted surface scientist who at the time was a professor at the University of Munich in West Germany. Later, Campbell became a research staff member at Los Alamos National Laboratory, where he worked for several years.

Campbell joined the University of Washington chemistry faculty as an associate professor in 1989. He was promoted to professor in 1992 and became an adjunct professor of physics in 1994. Campbell was named codirector of Washington's Center for Nanotechnology in 1997 and since 1991 has served on the editorial board of the Journal of Catalysis.

E.V. Murphree Award in Industrial & Engineering Chemistry

Sponsored by ExxonMobil Research & Engineering Co. and ExxonMobil Chemical Co.

For JOHN N. ARMOR, catalysts are more than just a means of spurring reactions along. Armor, a senior scientist at Air Products & Chemicals, sees catalysis as a way to improve chemical processes and even solve some of the environmental and energy issues that the world faces today.

Armor is part of a breed that has become less common in the chemical industry: the corporate scientist who does long-term research aimed at solving fundamental problems. At the Air Products Catalysis Skill Center in Allentown, Pa., Armor says, scientists carry out the kind of "breakout innovation" that many chemical companies have abandoned.

Armor set up the center last year in order to consolidate catalysis efforts at Air Products and keep such innovation flowing. "We try to learn about the guts of why something works by building a fundamental understanding of its underlying catalytic basis," Armor says of the job he and his colleagues do. "We develop a knowledge base that can extend to relevant problems."

For example, in the hydrogen business, where Air Products has invested close to $1 billion in recent years, Armor's group has been instrumental in developing a fundamental understanding of the optimal catalysts for the production of hydrogen and carbon monoxide.

Armor came to the chemical industry after a short stint in academia. He earned a B.S. degree in chemistry from Pennsylvania State University in 1966 and a Ph.D. degree from Stanford University in 1970. He then taught at Boston University for four years before making the switch to industry, joining Allied Chemical in 1974 and moving to Air Products in 1985.

Unlike his academic counterparts, who are encouraged to publish their results, Armor can't disclose much of what he does for competitive reasons. "It's something you live with in industry," he says.

But among the achievements he can discuss, Armor says he is very proud of work carried out in the early 1990s on removing global-warming-inducing nitrogen oxides from power and manufacturing plant emissions. Defying conventional wisdom, Armor and colleague Yuejin Li developed a cobalt-exchanged zeolite catalyst that reduces NO and N2O with methane in the presence of oxygen.

Although Air Products did not commercialize the technology, Armor notes that researchers elsewhere continue to pursue it as an alternative to nitrogen oxide abatement methods based on ammonia or olefins as reductants. Li and Armor also discovered-and Air Products licensed-a very active cobalt-zeolite catalyst for the decomposition of N2O to N2 and O2; similar catalysts are now being used throughout the industry.

Leo E. Manzer, a DuPont fellow and longtime associate of Armor's, notes that Armor is rare among industrial scientists in his speaking out on the value of catalysis to mankind, particularly its ability to solve environmental problems. "It continues to amaze me how much effort is required in the U.S. to remind corporate and federal leaders of the significance of catalysis to our economy," Manzer says. "Over the years, John has taken on this challenge with great energy."

Armor points out that catalysis plays a role in almost 20% of the gross domestic product of the U.S. Most of this contribution is in the form of fuels and chemicals, he says, but environmental applications are among the fastest growing catalyst segments. "There are lots of opportunities in environmental areas with the rise of green issues such as carbon dioxide abatement," Armor says. "These are issues that can be resolved by a catalytic approach."
