Understanding Static and Dynamic Heterogeneities in Confined Water

该奖项由2009年《美国复苏与再投资法案》(Public Law 111-5)资助，波士顿大学的H.E.Stanley获得了理论与计算化学项目的资助，该奖项旨在开展与了解承压水中静态和动态非均质性相关的研究。这项研究计划的一个重点是回答这样一个问题：“散装水在受限条件下生存的特征是什么？”PI和他的学生与许多实验小组密切合作，帮助解释关于密闭、玻璃态和过冷水的实验。一个正在被实验和理论检验的假设是，对于承压水，存在液-液临界点。了解承压水的性质对包括生物学和地质学在内的许多领域都很重要。这项研究的结果正在被扩展到理解其他材料，如金属玻璃，这些材料现在被认为具有液态水的一些特征。研究生和本科生都对这项研究做出了贡献。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)H. E. Stanley of Boston University is supported by an award from the Theoretical and Computational Chemistry program to carry out research concerned with understanding static and dynamic heterogeneities in confined water. One focus of this research program is to answer the question: "what features of bulk water survive in confinement"? The PI and his students work closely with many experimental groups to help interpret experiments on confined, glassy and super-cooled water. One hypothesis that is being tested both experimentally and theoretically is the existence, for confined water, of a liquid-liquid critical point.Understanding the properties of confined water is important to many fields including biology and geology. The results from this research are being extended to understand other materials such as metallic glasses that are now thought to share some features of liquid water. Both graduate students and undergraduates contribute to this research.
