In this U.S.-Brazil planning visit supported by the Americas Program of the Office of International Science and Engineering, Richard G. Weiss of Georgetown University will explore research collaboration in the area of gel science with Prof. Teresa D. Z. Atvars of the University of Campinas in Brazil. Professor Atvars has a fluorescence microscope that can follow the nucleation and subsequent aggregation steps leading to self-assembled fibrillar networks (SAFINs) of molecular gels. This general research theme is part of a project currently being being pursued in Prof. Weiss's laboratory. The information to be obtained from the proposed research is central to understanding a wide range of different nucleation-crystallization phenomena, an important area in sol-gel chemistry. The approaches and training of Profs. Atvars and Weiss are quite different, and their areas of expertise are complementary. These differences and complementarities are expected to produce results that would not be possible in either of their laboratories alone.The prospective collaborative research project will provide a blueprint for those who are employing gels, including molecular gels, for applications in health fields (rates of drug delivery for implanted devices or dermal patches), enhanced oil recovery (at the shale cracking stage), and even art conservation. There will also be an important component of human resource development. In addition to having both Brazilian and US graduate students work side by side to learn new techniques and approaches to problem solving, the US students will also learn how to adapt to a different culture.

在国际科学与工程办公室美洲项目支持下的这次美国-巴西计划访问中，乔治城大学的 Richard G. Weiss 将与坎皮纳斯大学的 Teresa D. Z. Atvars 教授探讨凝胶科学领域的研究合作。巴西。 Atvars 教授拥有一台荧光显微镜，可以跟踪成核和随后的聚集步骤，从而形成分子凝胶的自组装纤维网络 (SAFIN)。 这一总体研究主题是韦斯教授实验室目前正在进行的项目的一部分。 从拟议研究中获得的信息对于理解各种不同的成核-结晶现象至关重要，这是溶胶-凝胶化学的一个重要领域。 教授的方法和培训。 Atvars 和 Weiss 有很大不同，而且他们的专业领域是互补的。 这些差异和互补性预计将产生仅在他们的实验室中不可能实现的结果。前瞻性合作研究项目将为那些使用凝胶（包括分子凝胶）在健康领域应用的人提供蓝图（药物比率）输送植入设备或真皮贴片）、提高石油采收率（在页岩裂解阶段），甚至艺术品保护。人力资源开发也将是一个重要组成部分。 除了让巴西和美国研究生并肩学习解决问题的新技术和方法外，美国学生还将学习如何适应不同的文化。
