Understanding Static and Dynamic Heterogeneities in Confined Water

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。波士顿大学的E. Stanley获得了理论与计算化学项目的一项奖励，以开展有关理解承压水中静态和动态非均质性的研究。这个研究项目的一个重点是回答这个问题：“在封闭条件下，散装水的哪些特征仍然存在？”PI和他的学生与许多实验小组密切合作，帮助解释在密闭、玻璃状和过冷水上的实验。一个正在实验和理论上验证的假设是，对于承压水来说，存在一个液-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某些特征。研究生和本科生都参与了这项研究。

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.
