Using Carbon-Based Nanomaterials and Microscale Geometry for Enhanced Thermionic Energy Conversion in Space Applications

Completed TRL 3 (started at 2, targeting 3)

Description

The hypothesis of this research is that using carbon-based nanomaterials (CBN) electrodes in a microscale thermionic energy conversion (TEC) device operated at modest pressures will increase both the power density and conversion efficiency of TEC devices. For this NASA Fellowship, I will work to improve the performance of thermionic energy converters for space applications by investigating the fundamental physics of CBN-enhanced microscale thermionic energy conversion. I will focus my research efforts on the development and characterization of CBN as thermionic emitters, the development of microscale TEC devices, and the prediction of CBN-enhanced microscale TEC using particle-based simulation models. This work will increase the understanding of the complex interaction between ions and thermionic emission, and push them further toward the development of functional TEC devices.

Benefits

This work will increase the understanding of the complex interaction between ions and thermionic emission, and push them further toward the development of functional thermionic energy conversion (TEC) devices.

How to get involved

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
