9815256LevyThis award supports a three year collaborative research project between Professor Ronald Levy of Rutgers University in New Brunswick and Professor Masaru Nakahara of Kyoto University in Japan. The researchers will undertake theoretical and experimental studies of aqueous solutions under extreme conditions. The study of water and aqueous solutions under conditions that are far from standard pressure and temperature is receiving increasing attention. The potential industrial importance of supercritical water, as a good solvent for separations and reactions provides one motivation for this effort. The recent development of new experimental and theoretical high-pressure techniques to study problems in biophysical chemistry is another. The three goals of the project are: 1) a study of the role of polarizability in the physical chemistry of aqueous solutions under extreme conditions; 2) further development of hydration shell models based on statistical mechanics to describe the thermodynamics and dynamics of aqueous solutions as a function of temperature and pressure; and 3) computer simulations of biomolecular hydration at high pressure and temperature. This project brings together the efforts of two laboratories that have complementary expertise and research capabilities. The U.S. researchers have expertise in the study of solvent effects in physical and biophysical chemistry and the Japanese researchers are experts in the use of high resolution NMR to study the structure of supercritical water. Results of the research will have practical engineering applications in the field of chemical waste management where supercritical water is being used as a solvent for separations and reactions involving toxic wastes. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation.***

9815256Levy 该奖项支持新不伦瑞克省罗格斯大学 Ronald Levy 教授和日本京都大学 Masaru Nakahara 教授之间为期三年的合作研究项目。 研究人员将对极端条件下的水溶液进行理论和实验研究。 在远离标准压力和温度的条件下对水和水溶液的研究越来越受到关注。 超临界水作为分离和反应的良好溶剂，其潜在的工业重要性为这一努力提供了一个动力。 最近开发的用于研究生物物理化学问题的新实验和理论高压技术是另一个原因。 该项目的三个目标是：1）研究极化率在极端条件下水溶液物理化学中的作用； 2）进一步开发基于统计力学的水合壳模型，以描述水溶液的热力学和动力学作为温度和压力的函数； 3）高压高温下生物分子水合的计算机模拟。该项目汇集了两个具有互补专业知识和研究能力的实验室的努力。 美国研究人员在物理和生物物理化学中的溶剂效应研究方面拥有专业知识，日本研究人员是利用高分辨率核磁共振研究超临界水结构的专家。 研究结果将在化学废物管理领域具有实际的工程应用，其中超临界水被用作涉及有毒废物的分离和反应的溶剂。 通过思想和技术的交流，该项目将拓宽我们的基础知识基础并促进国际理解与合作。***
