In this project supported by the Chemical Structure, Dynamics and Mechanisms Program of the Division of Chemistry, Professor Mikhail Anisimov of the University of Maryland College Park and his research group will employ static and dynamic light scattering, microrheology, slow scanning adiabatic calorimetry, optical and electron microscopy, and X-ray and neutron scattering to characterize the structure of aqueous solutions of alcohols and small amphiphilic ions. The general goal of the research would be to provide useful experimental data and insight into the question of equilibrium or long-lived mesoscale structures.The results of the proposed research may have a broad impact on the understanding of the role which water and aqueous solutions play in nature, industry, and in biological systems. In particular, the research may be relevant to various possible applications, such as nano-encapsulated oxygen delivery or protein unfolding and protein dehydration in aqueous solutions, and new smart materials resulting from self-assembly in solution.

在化学系化学结构、动力学和机理计划的支持下，马里兰大学帕克分校的米哈伊尔·阿尼西莫夫教授和他的研究小组将利用静态和动态光散射、微观流变学、慢扫描绝热量热、光学和电子显微镜以及X射线和中子散射来表征醇和两亲小离子的水溶液的结构。这项研究的总体目标将是提供有用的实验数据和对平衡或长寿命中尺度结构问题的洞察。拟议的研究结果可能会对理解水和水溶液在自然、工业和生物系统中所起的作用产生广泛的影响。特别是，这项研究可能与各种可能的应用相关，如纳米包裹的氧气输送或蛋白质在水溶液中的展开和蛋白质脱水，以及通过在溶液中自组装产生的新的智能材料。
