RTM370 imide resin was developed to address the limitations of conventional imide resins, which are generated from commercially available symmetrical biphenyl dianhydride...
Briefs: Automotive
Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous, ultralight...
Briefs: Sensors/Data Acquisition
Lasers play roles in many manufacturing processes, from welding car parts to crafting engine components with 3D printers. To control these tasks, manufacturers must ensure that their lasers fire at the...
Briefs: Transportation
NASA's Glenn Research Center has developed a novel solid oxide fuel cell (SOFC) with five times the specific power density of currently available SOFCs. This highly efficient SOFC can operate on a wide...
Briefs: Manufacturing & Prototyping
Researchers have developed a new propulsion concept for swimming robots that exploits temperature fluctuations in the water for propulsion without the need for an engine, propellant, or power supply.
Briefs: Robotics, Automation & Control
A process has been developed that enables the production of a 2-mm flat camera. The lens is partitioned into 135 tiny facets, similar to the eyes of an insect. The facetVISION camera is suitable...
Briefs: Test & Measurement
It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...
Briefs: Transportation
With novel optoelectronic chips and a new partnership with a top silicon-chip manufacturer, MIT spinout Ayar Labs aims to increase speed and reduce energy consumption in computing, starting with...
Briefs: Transportation
As the demand for air transportation increases, the capacity of the current U.S. ATM system will eventually be stressed to its limits. New technologies in communication, navigation, and surveillance (CNS),...
Briefs: Electronics & Computers
The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...
Briefs: Transportation
A battery pack is only as strong as its weakest cell. As battery packs become larger and more integral to the stable operation of devices and systems, the need to monitor battery dependability and performance in...
