Collaborative:Development of a Hydrogen Discriminating Low Temperature 1-D Nanocomposite Micro-Sensor

摘要本课题的目标是利用一种新型纳米材料集成微传感器，实现室温下氢气检测的快速、灵敏和判别检测。该方法基于导电氧化物的一维多孔纳米结构和阵列结构。纳米结构将通过溶胶-凝胶加工、静电纺丝和快速激光诱导自组织制备，传感器平台将通过光刻方法制备。这项工作的智力价值将来自于纳米制造、材料化学和电子学的基本科学和工程原理在新型传感器设计中的应用。具体来说，了解一维纳米结构、结构、氧化物化学和电子响应之间的关系，将为设计和制造纳米级快速灵敏的金属氧化物半导体传感器提供定量基础。更广泛的影响将来自两所机构和邻近学校在科学和工程领域的前沿跨学科研究和教育活动，涉及代表性不足的本科生、研究生和K-12学生/教师。该项目将确保在国家迫切需要的领域培养下一代科学家和工程师。培训和教育计划将使学生具备自下而上的纳米材料合成和自上而下的器件设计方法的综合使用的知识和技能。考虑到最近公众对清洁替代能源需求的认识，美国国家科学基金会对这种氢传感器研究的支持为具有成本效益的设计和制造这种传感器提供了一个新的科学和工程跳板，这对氢作为能源的储存、运输和分配至关重要。

Project AbstractThe objective of this collaborative proposal is to realize fast, sensitive and discriminating detection of hydrogen detection at room temperature using a novel nanomaterial integrated microsensor. The approach is based on one dimensional porous nanostructures and array architectures of conducting oxides. The nanostructures will be prepared by sol-gel processing, electrospinning and fast laser induced self-organization while the sensor platform will be prepared by lithographic approaches. The intellectual merit of this work will come from the application of fundamental scientific and engineering principles of nanofabrication, materials chemistry and electronics to novel sensor design. Specifically, understanding the relationships between one dimensional nanostructure, its architecture, oxide chemistry, and electronic response will permit a quantitative basis for design and fabrication of fast and sensitive metal oxide semiconductor sensors at the nanoscale. The broader impact will come from cutting-edge interdisciplinary research and education activities in science and engineering across two institutions and neighboring schools involving underrepresented undergraduates, graduates and K-12 students/teachers. This project will ensure training of next-generation scientists and engineers in the areas of critical national need. The training and educational programs will equip the students with knowledge and skills for the integrated use of bottom-up nanomaterial synthesis and top-down device design approaches. Considering the recent public awareness on the need of clean alternative energy, the NSF support for this hydrogen sensor research provide a novel scientific and engineering springboard for the cost-effective design and fabrication of such sensors, that are crucial for storage, transportation, and distribution of hydrogen as an energy source.
