Event sponsorsWeston T. Borden served on UW Chemistry’s faculty for 31 years, before becoming the first Robert A. Welch Professor of Chemistry at the University of North Texas in 2004. His research involved the use of molecular orbital (MO) theory and MO-based calculations to understand and predict the structures and reactions of organic and organometallic molecules. He became University Distinguished Research Professor Emeritus at UNT in 2018.
Sheila Borden received a B.Sc. and Ph.D. in chemistry from the University of Newcastle upon Tyne. After a year at the University of Oslo, she joined the staff of the Royal Society of Chemistry, where she became managing editor of the RSC's organic chemistry journals. After moving with Wes to Texas in 2004, she took charge of the JACS Editorial Office at UNT.
Description

Borden Endowed Lecture in Theoretical Chemistry

Professor James L. Skinner – Institute for Molecular Engineering, University of Chicago

"Anomalies in ambient and supercooled water: is there a second critical point lurking nearby?"

Liquid water displays a number of anomalies, including the famous density maximum at 4 C and the compressibility minimum at 46 C. Moreover, the density decreases markedly and the compressibility increases rapidly as the temperature is further decreased below 0 C and the liquid becomes supercooled. Finally, the density decrease upon freezing is also anomalous.  In this talk I will explore possible microscopic and thermodynamic origins of these anomalies, present experimental, simulation, and theoretical evidence for the presence of a liquid-liquid critical point in deeply supercooled water, and argue that this critical point, even though far removed in temperature and pressure from ambient water, is nonetheless responsible for its anomalies.
