The Nation Science Foundation-supported Center for Innovation, Research and Education in Environmental Nanotechnology at the University of Puerto Rico - Rio Piedras is dedicated to the development of nanomaterials and devices to address environmental pollution, while developing a diverse science, technology, engineering and mathematics workforce. The Center's research endeavors include development of nanomaterials for water purification, soil remediation, and resource recovery. Center investigators submitted a Rapid Response (RAPID) proposal to the National Science Foundation to conduct quick-response research on a natural disaster. The combined paths of Hurricane Irma on September 6, 2017, and Hurricane Maria on September 20, 2017, had devastating effects across the entire island of Puerto Rico. The urban coastal wetland that serves as the Center testbed, source of substrates for nanostructure development, and substrate for biofuel production, was severely affected by the hurricane winds, and by massive flooding due to fresh water flowing from upland sources.Center research staff at the University of Puerto Rico Rio Piedras will (1) assess hurricane impact and subsequent wetland regeneration: the substrate source for nanostructure construction, substrate source for biofuel generation, and the plant species to be used in combination with nanostructures for nano-phyto remediation work, and (2) quantify the heavy metal inputs to the testbed wetland.INTELLECTUAL MERIT: Proposed research will contribute to knowledge concerning the impact of extraordinary natural climatological events, such as a massive hurricane and the subsequent climatological conditions in the area, impact regeneration dynamics of an urban coastal wetland system, and its capacity for heavy metal remediation. BROADER IMPACT: Proposed work will advance discovery and understanding of how massive hurricane impacts affect coastal wetlands under a framework of urban and industrial conditions. Project activities provide hands-on training and learning, by involving graduate and undergraduate students in research. The project will broaden the participation of under-represented groups in science technology, engineering and mathematics fields.

在波多黎各大学 - 里约皮埃拉斯（Rio Piedras）的国家科学基金会支持的创新，研究与教育中心致力于开发纳米​​材料和设备，以应对环境污染，同时开发多样化的科学，技术，工程，工程和数学工作人员。 该中心的研究努力包括开发用于净水，土壤修复和资源回收的纳米材料。中心调查人员向国家科学基金会提出了快速响应（快速）提案，以对自然灾害进行快速响应研究。 2017年9月6日，飓风Irma和2017年9月20日的玛丽亚飓风在整个波多黎各岛上产生了毁灭性的影响。充当中心测试的城市沿海湿地，纳米结构开发的基质来源和生产生物燃料的基板受到飓风风的严重影响，以及由于来自高地源的淡水而引起的大规模洪水。纳米结构的结构，生物燃料生成的底物来源以及与纳米含量补救工作的纳米结构结合使用的植物物种，以及（2）量化测试床湿地的重金属输入。启发性的研究：拟议的研究将有助于伴随着非本质的自然气氛的知识，例如，既有自然的气氛又会产生诸如超级气候的影响。城市沿海湿地系统的再生动态及其重金属修复的能力。更广泛的影响：拟议的工作将提高发现并了解在城市和工业条件框架下巨大的飓风影响如何影响沿海湿地。通过涉及研究生和本科生的研究，项目活动提供动手培训和学习。该项目将扩大代表性不足的团体参与科学技术，工程和数学领域的参与。
