Lecture Today on If There Are Two Forms of Liquid Water
The Department of Physics in the J. William Fulbright College of Arts and Sciences presents its Physics Colloquium, titled "Are There Two Forms of Liquid Water?" to be given by H. Eugene Stanley, professor of physics at Boston University. The lecture will be from 4-5 p.m. Friday, Oct. 13, in PHYS 133. Refreshment will begin at 3:30 p.m. in PHYS 134.
Stanley will introduce some of the 73 documented anomalies of the most complex of liquids, water—focusing on recent progress in understanding these anomalies by combining information provided by recent experiments and simulations on water in bulk, Nano confined and biological environments designed to test the hypothesis that liquid water has behavior consistent with the novel phenomenon of "liquid polymorphism" in that water can exist in two distinct phases.
He will also discuss very recent work on Nano confined water anomalies as well as the apparently related, and highly unusual, behavior of water in biological environments. Finally, he will discuss how the general concept of liquid polymorphism is proving useful in understanding anomalies in other liquids, such as silicon, silica, and carbon, as well as metallic glasses, which have in common that they are characterized by two characteristic length scales in their interactions.
