  1. For Topic 26-OS1, does “commercial transport modernization” require direct deployment in motor-carrier operations, or can upstream aviation

    For Topic 26-OS1, does “commercial transport modernization” require direct deployment in motor-carrier operations, or can upstream aviation training and readiness systems qualify if they support downstream safety outcomes through predictive safety analytics?

  17. For this topic, does transportation safety include assuring the essential navigational signals that GNSS depends on?

    One of the growing threats to aviation, maritime, and ground transportation is the increasingly vulnerable state of the navigational signals these systems depend on. GNSS threats are on the rise, with low-cost spoofers and jammers (available for as little as $50) now capable of compromising the navigational capabilities of large shipping vessels and commercial aircraft. This challenge is difficult to address, as the assets that defend against such spoofing and jamming can cost thousands of dollars at minimum, placing them out of reach for most operators across the U.S. transportation network.

    It would seem that a solution that could solve…

  18. Verified mobility-event data

    Would verified mobility-event data generated by a controlled commercial passenger transportation fleet be considered an eligible voluntary industry data source for Phase I research, if the data is privacy-preserving and used to develop proactive safety indicators rather than to fund transportation operations?

  19. Oxalate/formate-based mineral recovery chemistry within scope for 26-PH1?

    For topic 26-PH1, would a chemical process focused on improving recovery of rare earth / critical minerals from end-of-life lithium-ion battery materials be considered responsive if it uses low-carbon oxalate/formate-based precipitation chemistry?

    Specifically, we are considering a Phase I concept to demonstrate selective precipitation/recovery of representative critical minerals from battery-recycling streams, benchmarked against conventional oxalic acid/oxalate routes, with attention to safer handling and improved recovery economics.

    Or is this topic primarily focused on residual-energy removal / battery de-energizing technologies rather than downstream mineral recovery chemistry?
