1134289Asefa This NSF award by the Environmental Health and Safety of Nanotechnology program supports work by Professor Tewodros Asefa to develop and investigate new classes of TiO2- and ZnO-based core-shell-shell nanoparticles (particles with one ten-thousandth the diameter of a human hair in size) capable of efficiently photo-decomposing or converting in the presence of sunlight common organic pollutants in the environment and in waste water into harmless or even useful substances such as CO2 and H2O. The successful accomplishment of the proposed work will result in not only robust materials useful for environmental decontamination but also easily recoverable and recyclable materials for multiple uses. Such materials will be useful for recycling waste water at a time of shortages of clean water at various locations in the U.S. and around the world. The research findings should also inform future research directions in synthetic approaches to novel multifunctionally-doped efficient nanomaterials for efficient photodegradation of organic pollutants in waste water. The project?s societal benefits include advancement of systematic, less costly synthetic methods to create materials capable of cleaning environmentally prevalent pollutants from waste water with the direct use of solar energy. The project will also allow the training of a number of post-doctoral researchers and graduate and undergraduate students who will be involved in the research project in the PI's lab. These students, including those from groups underrepresented in sciences and engineering fields, will be trained in a variety of synthetic methods involving nanomaterials synthesis, their characterization, photocatalysis, and scientific/engineering approaches utilized in environmental remediation. Furthermore, the PI will use results from the proposed work in his undergraduate and graduate course offerings in nanoscience, materials chemistry and nanotechnology at Rutgers, The State University of New Jersey. This project will also enable the PI to continue to involve high school senior students in research through Rutgers' Governor's School program during the summer semester. In addition, the PI will use the results of the research project in presentations to teach the potential implications of nanoscience and nanotechnology for general audiences attending Science Fairs, as well as in Discovery Day activities at Rutgers. The PI will further use these opportunities to draw students' interest into science, technology, engineering, and mathematics (STEM) fields and to change students' (and parents') perceptions about science and engineering disciplines.

1134289SASEFA纳米技术的环境健康和安全计划的NSF奖支持Tewodros Asefa教授的工作，以开发和调查新的Tio2-和ZnO基于TiO2和ZnO的新类别的核心壳壳纳米颗粒（具有十分之一的人类直径的颗粒大小的头发）能够在存在环境中的阳光常见有机污染物和废水中有效地进行拍摄或转换，以无害甚至有用的物质，例如CO2和H2O。拟议的工作的成功完成不仅会导致可靠的材料可用于环境净化，而且还可以易于回收和可回收的材料多种用途。此类材料对于在美国和世界各地的清洁水短缺时将废水回收有用。研究结果还应以合成方法的未来研究方向为未来的研究方向提供信息，用于新型多功能有效的纳米材料，以有机污染物在废水中有效的光降解。该项目的社会利益包括进步系统的，成本较低的合成方法，以创建能够直接使用太阳能从废水中清洁环境普遍的污染物的材料。该项目还将允许培训许多博士后研究人员以及将参与PI实验室研究项目的研究生和本科生。这些学生，包括来自科学和工程领域中代表性不足的小组的学生，将接受各种涉及纳米材料合成，其表征，光催化以及科学/工程方法的合成方法培训。此外，PI将在新泽西州立大学罗格斯（Rutgers）的纳米科学，材料化学和纳米技术的本科和研究生课程中使用拟议的工作的结果。该项目还将使PI能够在夏季学期通过Rutgers的州长学校课程参与高中生研究。此外，PI将利用研究项目的结果来教授纳米科学和纳米技术对参加科学博览会的一般受众以及Rutgers的发现日活动的潜在影响。 PI将进一步利用这些机会吸引学生对科学，技术，工程和数学（STEM）领域的兴趣，并改变学生对科学和工程学科的看法。
