The 876th IMS colloquium

Seminar & Events Detail

Lecture Title	"The Mystery of Water; X-rays Provide Unique Insights"
Date	Friday 6 November 2015 16:00
Lecturer	Prof. Anders Nilsson (Department of Physics, Stockholm University)
Place	OKAZAKI Conference center, roomC
Summary	The anomalous physical properties of water are responsible for sustaining much of life on earth; for example, water displays a higher heat capacity than common liquids and expands upon freezing. Some of these anomalous physical properties become dramatically enhanced upon supercooling below the freezing point. I will present recent x-ray spectroscopy and scattering measurements, using both synchrotron radiation at SSRL, SPring-8 and the x-ray laser at LCLS, at temperatures from deep supercooling to boiling. The results shows that the liquid can be described as fluctuations between two types of local hydrogen bonded structures driven by incommensurate requirements for minimizing enthalpy and maximizing entropy. The connection of these results to low and high density water, the waters anomalies and the potential liquid-liquid transition and 2nd critical point model will be discussed.
