A flexible mirror film electrically switches between reflective and transparent states. By applying (+) voltages, hydrogenation occurs and creates transparency. When (-) voltages are used, the switchable mirror returns to its original reflective state within 10 seconds. The technology allows...

New electrically charged, polarized, proprietary alloys create thrust to lift small aircraft, commonly referred to as Personal Ultralight Vehicles (PAVs), without the need of a propeller, jet, balloon, or rockets. The ion electric air propulsion is considered a clean technology that...

A company seeks alternative ways of preparing crucibles for the vapor deposition process. Currently, up to a kilogram of an alkalihalide salt is melted electrically in a tantalum crucible within a vacuum chamber, and the vapor is deposited on a metal substrate. The...

New home-use and point-of-care diagnostic medical technologies are needed. The diagnostics kits should monitor diseases not easily measured. Testing may be done within the device, or the device may be a tethered testing head that reports to a central diagnostics facility. The product can be...

A process to enhance the electron-hole wave functions overlap – resulting in high-efficiency quantum well light-emitting diodes (LEDs) emitting in the green and yellow wavelengths – has been developed. This proposed technique changes the polarity of the structure and diminishes the piezoelectric effect. It is...

Sam Ortega, manager of the NASA Centennial Challenges Program, leads progressive aerospace initiatives, encouraging the participation of independent teams, individual inventors, student groups, and private companies. Most recently, the program’s...
