摘要：本提案建议继续支持东北大学Geoffrey Davies博士和美国东北大学Geoffrey Davies博士的研究小组的合作。埃及亚历山大大学的Mohamed A. El- Sayed和Ahmed El- toukhy。这些研究小组发现并发展了多金属嬗变化学的新领域。金属转化是用从化学试剂中获得的其他金属元素取代目标材料中的金属元素。迄今为止的研究成果相当可观，已发表了九篇研究论文，另有八篇论文已提交出版或处于后期准备阶段。这项原始研究揭示了六个新的重要领域，被认为值得进一步研究和探索。这项新研究预计将对化学、材料和催化科学产生重大影响。此外，它将为学生提供许多学习现代无机化学和物理化学的机会。研究范围：拟议的研究计划为期两年，主要研究人员在其同行的实验室工作。这两名埃及科学家将在东北大学度过总共12个月的时间。戴维斯博士将在亚历山大大学工作三个月。这种分工将有利于两个研究小组，使彼此接触到每所大学的研究设施，同时使每个化学系的研究生有机会熟悉科学思维。外国合作大学的成功科学家所采用的技术和解决问题的方法。提出的新研究的六个领域是：o苯酚氧化偶联的结晶和电化学研究o金属转化的催化效应o低温二聚铜(I)-二氧的金属转化速率规律和机理多核铜(I)-醌类二氧配合物的氧化系统本提案符合发展中国家科学计划推进国际科学知识交流的目标，并有助于促进国际科学知识交流加强发展中国家的科学。

ABSTRACT NARRATIVE Description: This proposal proposes the continued support of the collaboration of the research groups of Dr. Geoffrey Davies of Northeastern University and Drs. Mohamed A. El- Sayed and Ahmed El-Toukhy of the University of Alexandria, Alexandria Egypt. These research groups have discovered and developed a new field of polymetallic transmetalation chemistry. Transmetalation is the replacement of metallic elements in a target material with other metallic elements received from chemical reagents. Research to date has been substantial resulting in nine published research papers with eight additional papers submitted for publication or in the advanced stage of preparation. This original research has revealed six new areas of importance that are considered worthy of further research and exploration. The new research is expected to have a large impact on chemical, materials and catalytic science. Further, it will provide numerous learning opportunities for students in modern inorganic and physical chemistry. Scope: The proposed research is programmed for two years with the principal investigators working in their counterpart's laboratories. The two Egyptian scientists will spend a total of 12 months at Northeastern University. Dr. Davies will work at Alexandria University for three months. This work division will advantage both researh groups in exposing one and another to the research facilities of each university, while giving the graduate students of each chemistry department opportunities to become acquainted with the scientific thinking, techniques and problem solving approaches employed by successful scientists from the cooperating foreign university. The six areas of proposed new research are: o Crystallization and Electrochemical Studies o Mechanisms of Phenolic Oxidative Coupling o Catalytic Effects of Transmetalation o Transmetalation Rate Laws and Mechanisms o Low Temperature Dimeric Copper(I)-Dioxygen Systems o Oxidation of Polynuclear Copper(I)-Dioxygen Complexes with Quinones This proposal meets the objectives of the Science in Developing Countries Program of advancing the international exchange of scientific knowledge and does contribute to the enhancement of science in a developing country.
