Completed TRL 3 (started at 1, targeting 3)
Conduct a systematic computational study on the physical and electro-mechanical properties of Boron Nitride Nanotubes (BNNTs) to evaluate their functional performance as dependent on their atomic structure.
Boron-nitride nanotubes (BNNTs) exhibit electroactive behavior in response to mechanical deformation, but the origin of this phenomenon is not well understood. Our goal is to explain how atomic scale structural changes produce macroscopically observable electrical behavior. We are developing and validating a new interatomic potential for use in molecular dynamics simulations aimed at systematically exploring the nature of the electo-mechanical coupling observed in this material.
Specific outcomes from this work will be a validated BN interatomic potential that incorporates the physical effects required to correctly represent the electroactive properties of BNNTs and a mechanistic understanding of how their atomic structure couples to an external electric field. Achieving this will permit the development of lightweight structural sensors/actuators for IVHM in extreme environments with previously unachievable combinations of strength, toughness, and thermal stability.

Listed on TechPort itself — the most direct way to ask about this specific project.
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.
