题目：Ionic Liquids : A look at the role of water on the structure and dynamics
Room-temperature ionic liquids (RTILs) are receiving increased attention due to their unique properties, including non-volatility and solvating capability, leading to a wide range of potential uses in catalysis, separation technology, photovoltaics and fuel cells. Understanding how the structure and dynamics of RTILs change when water is added to them is essential. Until now, most of the information concerning the behavior of IL-water mixtures comes from computer simulations. While these can provide a very detailed picture of both the structure and dynamics of such mixtures, the potentials employed and their results need to be validated experimentally. The combined use of neutrons and high-energy x-rays has proved to be a powerful probe of the structure and dynamics of such complex condensed systems.
Marie-Louise Saboungi is Distinguished Professor of Physics at the Marie Curie University in Paris. She served as Director of a research institute CRMD, as Co-Director of the Materials, Energy and Geosciences and as a Research and Education Minister nominee of the National Committee for the promotion of the Professors of the French Universities. Prior to that she was a Senior Scientist at Argonne National Laboratory, where she established close collaborations with the University of Chicago’s James Franck Institute and with Cornell University. She is a Fellow of AAAS, APS, JSPS, and the Alexander von Humboldt Foundation, from which she received the Helmholtz-Humboldt Prize in 2008. She has served on international advisory committees for DOE, NSF, CNRS, ANR and AERES, and in the European Community where she is a member of the Advisory Board of the FET-Horizon 2020. She has organized and chaired over fifty international conferences and workshops including two Gordon Research Conferences in the U.S. She has an honorary Doctorate from the University of the Andes, Venezuela.
David L. Price is a researcher at the Research Center for Extreme Conditions and Materials: High Temperature and Irradiation in Orleans, France. Previously he was on the staff at Argonne National Laboratory where he served variously as Senior Scientist, Director of the Solid State Science Division and Director of the Intense Pulsed Neutron Source (IPNS). He received the Warren Prize from the American Crystallographic Association in 1997 and an Alexander Von Humboldt Research Award in 1998. He is a Fellow of the American Physical Society, the Institute of Physics, UK, and the Neutron Scattering Society of America. His specific research interests include order and disorder in solids and liquids, high-temperature levitated materials, the glass transition and melting, neutron diffraction with isotope substitution, and inelastic neutron scattering.
