The Chemistry of Drink & More at Clarkson University Shipley Lectures April 18 & 19

Professor Richard N. Zare says, "Fizz and foam has always spelled fun to me as early as I can remember... Imagine the surprise to find that bubbles do occupy an important place in contemporary technology."

Richard N. ZareZare, the Marguerite Blake Wilbur Professor in Natural Science at Stanford University, will deliver the two lectures of Clarkson University's 18th Shipley Distinguished Lectureship, April 18 and 19.

He will speak about "The Chemistry of Drink” on Thursday, April 18, at 4:15 p.m. in Science Center Room 360. The presentation will be preceded by a 3:30 p.m. reception.

Zare's lecture will be filled with demonstrations illustrating the world of bubbles, answering questions like “Why do bubbles in a carbonated beverage grow in size when they rise?” and “Do all bubbles in a carbonated beverage rise upward?” He says that those attending should be prepared for some surprises as he explores the topic of chemical "fizzics" and that "only the brave should sit in the front row."

Zare will explain the important place that bubbles occupy in contemporary technology, such as in the recovery of oil from tired oil wells into which bubbles are injected to help lift heavier crude to the surface, much like a raisin can be made to rise in a glass of champagne.

Another example is in gas-liquid reactions that rely on bubbles to increase the contact area between the two phases. This process leads to interesting chemical separations in which froth is used to achieve a partial separation of components in a mixture.

For students, faculty and the more technically inclined, Zare will then present “Cavity Ring-Down Spectroscopy: A New Way to Make Ultra Sensitive Absorption Measurements" on Friday, April 19, at 11 a.m. in Bertrand H. Snell Hall Room 213.

Zare will review the physical basis of a cavity-enhanced absorption technique called cavity ring-down spectroscopy and present some striking applications, including the measurement of stable isotope ratios without the use of mass spectrometers.

Zare is a graduate of Harvard University, where he received his bachelor of arts degree in chemistry and physics in 1961 and his Ph.D. in chemical physics in 1964. He taught at the Massachusetts Institute of Technology, the University of Colorado and Columbia University, moving to Stanford University in 1977. Zare was named chair of the Department of Chemistry in 2005 and in 2006 was named a Howard Hughes Medical Institute (HHMI) Professor.

He is renowned for his research in laser chemistry, resulting in a greater understanding of chemical reactions at the molecular level. By experimental and theoretical studies Zare has made seminal contributions to our knowledge of molecular collision processes and contributed very significantly to solving a variety of problems in chemical analysis. His development of laser induced fluorescence as a method for studying reaction dynamics has been widely adopted in other laboratories.

Zare has received numerous honors and awards, teaching awards and honorary degrees. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, American Philosophical Society, and the World Jewish Academy of Sciences.

The Shipley Lectures are sponsored by the Shipley Family Foundation, with support from Clarkson's Center for Advanced Materials Processing (CAMP). The public is cordially invited to attend.

The Shipley Distinguished Lecture Series was initiated in 1994 through a generous gift from the late Lucia and Charles Shipley through the Shipley Family Foundation. Over that period distinguished speakers from around the world, including eight Nobel Laureates, have presented talks.

The purpose of the lectures is to promote scholarly achievements at Clarkson by providing the opportunity for idea exchange and active learning, as well as allowing undergraduate and graduate students to meet the most prestigious speakers from all over the world.

For more information about the lectures, please contact lectureship organizer Egon Matijevic, Victor K. LaMer Professor of Colloid and Surface Science, at 315-268-2392.

Clarkson University launches leaders into the global economy. One in five alumni already leads as a CEO, VP or equivalent senior executive of a company. Located just outside the Adirondack Park in Potsdam, N.Y., Clarkson is a nationally recognized research university for undergraduates with select graduate programs in signature areas of academic excellence directed toward the world’s pressing issues. Through 50 rigorous programs of study in engineering, business, arts, sciences and health sciences, the entire learning-living community spans boundaries across disciplines, nations and cultures to build powers of observation, challenge the status quo, and connect discovery and engineering innovation with enterprise.
