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

目的：这项拟议的研究将开发能够检测基于过氧物的简易炸药的传感器。恐怖组织越来越多地使用这类爆炸物，而适当的探测设备却很少，这使这一目标成为一个重要目标。智力价值：该项目将采用为中和恐怖分子爆炸物而开发的成功技术，并将其应用于开发探测爆炸物的传感器。将开发的传感器将是非典型的，因为它们将能够识别以过氧化氢为基础的炸药和传统的硝基有机炸药。这项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质提供解决方案。将开发的传感器设备范围从非常灵敏和坚固的电子比色和荧光传感器，到简单的测试条和墨水，可以确认过氧化氢炸药的身份。广泛影响，技术：开发的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。该实验还将促进我们对纳米粒子的合成、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和持久的积极影响，特别是在痕量分析领域。广泛的影响，教育：学生将在两个组成实验室轮流进行，以获得拟议研究的所有方面的经验。该项目还将结合俄克拉荷马州纳米网络倡议(NSF EPSCoR项目)提供纳米技术方面的讲座。还将通过一个网站和在当地高中和AP教师培训学院等其他场所举办的有关纳米技术的一般性讲座，进行公众宣传。还将向没有围墙的斯蒂尔沃特儿童博物馆捐款，将展品带到学校。

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.
