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.

摘要项目该协作提案的目标是使用新型的纳米材料集成微型传感器实现在室温下对氢检测的快速，敏感和区分检测。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 - 凝胶处理，静电纺丝和快速激光诱导的自组织来制备，而传感器平台将通过光刻方法制备。这项工作的智力优点将来自纳米制造，材料化学和电子产品的基本科学和工程原理的应用。具体而言，了解一维纳米结构，其结构，氧化物化学和电子响应之间的关系将为纳米级快速和敏感的金属氧化物半导体传感器的设计和制造提供定量基础。更广泛的影响将来自两家机构和邻近学校的科学和工程学的尖端跨学科研究和教育活动，涉及人数不足的本科生，毕业生和K-12学生/老师。该项目将确保对重要国家需求领域的下一代科学家和工程师进行培训。 培训和教育计划将为学生提供知识和技能，以综合使用自下而上的纳米材料合成和自上而下的设备设计方法。考虑到最近对清洁能源需要的公众意识，NSF对这项氢传感器研究的支持为具有成本效益的设计和这种传感器的制造提供了一种新颖的科学和工程跳板，这对于储存，运输和分布氢作为能源至关重要。
