EXP-SA: Development of Metal Oxide Bronzes for Detection of Military and Improvised Explosives

摘要：目的：研究开发基于过氧化物的简易爆炸物传感器。恐怖主义组织越来越多地使用这类爆炸物，而且缺乏适当的探测装置，因此这是一个重要的目标。智力优势：本项目将利用已开发成功的恐怖爆炸物中和技术，将其应用于爆炸物探测传感器的开发。将要开发的传感器将是非典型的，因为它们将能够识别基于过氧化物的爆炸物和传统的氮有机爆炸物。开发的技术还将为检测和消除实验室溶剂中形成的过氧化物提供解决方案。将开发的传感器设备将从非常敏感和强大的电子比色和荧光传感器到简单的测试条和墨水，可以确认过氧化物爆炸物的身份。更广泛的影响，技术：该技术可以在未来的研究中进行修改，通过改变表面催化剂来检测其他化学物质。实验也将推进我们对纳米粒子合成、反应性和表面性质的理解。这项研究可能会对实验室溶剂的安全和使用产生广泛而持久的积极影响，特别是在痕量分析领域。更广泛的影响，教育：学生将轮流在两个组成实验室，以获得拟议研究的各个方面的经验。该项目还将与俄克拉何马州纳米网络倡议（NSF EPSCOR项目）一起提供纳米技术讲座。公众外展活动也将通过一个网站和在当地高中和其他场所（如AP教师培训学院）举办的有关纳米技术的一般讲座来进行。还将向斯蒂尔沃特的无墙儿童博物馆捐款，该博物馆将展览带到学校。

ABSTRACTObjective:The proposed research will develop sensors that are capable of detecting improvised explosives based on peroxides. The ever-increasing use of such explosives by terrorist organizations and the paucity of suitable detection devices make this an important objective. Intellectual Merit:This project will take successful technology developed for neutralization of terrorist explosives and apply it to the development of sensors for the detection of explosives. The sensors that will be developed will be atypical because they will be capable of identifying both peroxide-based explosives and conventional nitroorganic explosives. The developed technology will also offer a solution to detecting and eliminating peroxides that form in laboratory solvents. The sensor devices that will be developed will range from very sensitive and robust electronic colorimetric, and fluorescent sensors to simple test strips and inks that can confirm the identity of peroxide explosives.Broader Impacts, Technological: The developed technology could be modified in future research to detect other chemicals by changing the surface catalysts. The experimentation will also advance our understanding of nanoparticle synthesis, reactivity, and surface properties. The research will likely have a widespread and lasting positive impact on the safety and use of laboratory solvents, especially in the area of trace analysis.Broader Impacts, Educational: The students will undergo rotation through the two constituent laboratories to gain experience in all aspects of the proposed research. The project will also provide lectures in nanotechnology in conjunction with the Oklahoma Nanonet Initiative (a NSF EPSCOR project. Public outreach will also be conducted through a web-site and general lectures concerning nanotechnology presented at local high schools and other venues such as AP Teacher Training Institutes. A contribution will also be made to Stillwater's Children's Museum Without Walls that takes displays to school.
