U.S.-Sierra Leone: Cooperative Research on Molecular Theories of Solubility

该提案要求获得资金，以允许Drexel大学材料工程系Witold K.Brostow博士与塞拉利昂大学Fourah Bay学院数学系教授Daniel ATe‘Jonah博士一起开展为期24个月的溶解性分子理论研究计划。这项研究将涉及气体在液体和无定形固体中的溶解度的统计力学，固体和液体在超临界流体中的溶解度，以及稀相体系的汽液平衡。乔纳教授已经发展了稀溶液和溶解度理论的第一个版本，而布罗斯托博士则对高度稀溶液的汽液平衡进行了实验观察，并建立了使该理论适用所需的等压膨胀率和等温压缩率方程。这项研究有望使人们更好地了解溶解度，并在工业上有助于提高材料的分离和纯化效率，以及更好地保护无定形聚合物免受气体溶解性对其性能的影响。该项目与发展中国家科学计划的目标相关，该计划旨在通过交流科学信息、思想、技能和技术，以及通过在互利问题上的合作，提高美国科学家和工程师与发展中国家同行之间的合作水平。美国和塞拉利昂的合作者是备受尊敬的科学家，在该提案领域拥有丰富的研究经验和富有成效的出版记录。

This proposal requests funds to permit Dr. Witold K. Brostow, Department of Materials Engineering, Drexel University, to pursue with Dr. Daniel Ate're' Jonah, Professor, Department of Mathematics, Fourah Bay College, University of Sierra Leone, for a period of 24 months, a program of research on molecular theories of solubility. The research will deal with the the statistical mechanics of solubility of gases in liquids and in amorphous solids, solubility of solids and liquids in supercritical fluids, and vapor-liquid equilibria of dilute systems. Professor Jonah has already developed the first version of the theory of dilute solutions and solubility, while Dr. Brostow has made experimental observations on vapor-liquid equilibria of highly dilute solutions and has developed equations for isobaric expansivity and isothermal compressivity which are required to make the theory usable. The research is expected to lead to a better understanding of solubility and would be useful in industry for improving efficiency of separation and purification of materials and also for better protecting amorphous polymers from the effects of gas solubility on their properties. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. The U.S. and Sierra Leonian collaborators are highly respected scientists with extensive research experience and productive publication records in the field of the proposal.
