0211253ElshallDescription: This award is to support a collaborative project between Dr. Hassan El-Shall and Dr. Charles Beatty, both at the Department of Materials Science and Engineering, University of Florida, Gainesville, Florida and Dr. Mervat Hassan, the Central Metallurgical Research and Development Institute, Cairo, Egypt. The three investigators plan to perform a systematic study of the factors and conditions that will lead to a significant improvement in the mechanical, thermal and solvent resistant properties of epoxy/clay nanocomposite used to manufacture tubesheet for high temperatures and chemically aggressive environments. Clay nanolayers are more effective in improving mechanical properties, thermal stability, dimensional stability and solvent resistance of the epoxy glassy matrix. Basic understanding of the mechanisms involved and role of clay properties are relatively unexplored. Scope: The results of this research will benefit researchers in academic and industrial organizations in both countries. Polymers reinforced by low weight percentages (1-10 wt.%) of nanoscopically dispersed organically modified layered silicates are attracting the attention of researchers because of the unprecedented suite of new and enhanced properties relative to the unfilled resin. The PIs have considerable experience in studying minerals and have the appropriate background to carry out this research. The subject is of particular interest to Egypt where high value added products derived from inexpensive starting materials are in great demand. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.

0211253 Elshall描述：该奖项是为了支持哈桑埃尔-Shall博士和Charles Beatty博士之间的合作项目，他们都在佛罗里达州盖恩斯维尔的佛罗里达大学材料科学与工程系，Mervat哈桑博士，埃及开罗的中央冶金研究与发展研究所。 三位研究人员计划对因素和条件进行系统研究，这些因素和条件将导致用于制造高温和化学侵蚀环境的管衬的环氧/粘土纳米复合材料的机械，耐热和耐溶剂性能的显着改善。粘土纳米层在改善环氧玻璃态基体的机械性能、热稳定性、尺寸稳定性和耐溶剂性方面更为有效。 对所涉及的机制和粘土性质的作用的基本理解相对未被探索。范围：这项研究的结果将有利于两国学术和工业组织的研究人员。 由低重量百分比（1-10重量%）增强的聚合物纳米级分散的有机改性层状硅酸盐树脂正吸引着研究人员的注意力，因为它相对于未填充的树脂具有前所未有的一系列新的和增强的性能。这些专业研究人员在矿物研究方面有相当丰富的经验，并具备进行这项研究的适当背景。 埃及对这一主题特别感兴趣，因为埃及对来自廉价原料的高附加值产品的需求很大。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。
