Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have been...

While silicon carbide (SiC) is an ideal material for building ultraviolet (UV) photodetectors, the absorbed photons get recombined in the first few nanometers at the surface due to a large absorption coefficient in the 200- to 250-nm wavelength band....

A real-time instrument was developed that could scan the atmosphere for toxic agents in order to alert communities to a biological or chemical attack.

Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D shapes.

Anon-catalytic pyrotechnic ignition system was developed for advanced green monopropellant systems operating with hydroxylammonium nitrate (HAN)-based monopropellant AF-M315E. This technology will provide increased performance and new operating regimes for future...

NASA’s Glenn Research Center has developed a method of using entangled-photon pairs to produce highly secure mobile communications that require mere milliwatts of power. Conventional gas Argon-ion laser sources are too large, expensive, and power-intensive to use in portable applications. By contrast,...

Engineers at Goddard Space Flight Center have overcome limitations plaguing the satellite sector since its inception through the development of a robotic system allowing for the autonomous capture and servicing of in-orbit satellites. By...
