Project Abstract

This two-year project is to manufacture a fast-response high-accuracy sensor for nitrogen oxides (NOx) detection using chemically stable high-surface-area ceramic nanowires.  To achieve this goal, ceramic nanowires will be first formed from ceramic slurry via the electrospinning process followed by a high temperature sintering in a controlled atmosphere.  The wires will then be integrated with an electrical circuit to be a portable sensor.  Finite element analysis will be employed to modify the electrospinning process to control the dimension and porosity of the spun nanowires in order to increase the surface area of the spun nanowires and thus maximize the detection sensitivity of the sensor.  The sintering process will be modified to maximize the surface area and control the nanostructure of the synthesized wires in order to improve the sensor performance.  The first year deliverables will be a custom made electrospinning system for ceramic nanowires preparation, a one dimensional mathematic model to analyze the electrospinning process, and nanowires of three different compositions.  The second year deliverables will include a portable NOx sensor and a complete three dimensional mathematic model of the electrospinning process.  In addition to the PI, one graduate student and two undergraduate students will work on this project.
