The EHD pump uses electric fields to move a dielectric fluid coolant in a thermal loop to dissipate heat generated by electrical components with a low-power system. The pump has only a few key components and no moving parts, increasing the simplicity and robustness of the system. In...

Fuel cells can deliver clean, reliable, and uninterrupted power nearly 100 percent of the time. Fuel cells offer the advantage of efficiency by converting chemical energy directly to electricity. They have no moving parts, thereby eliminating failures associated with pumps, blowers, heat exchangers, and other...

A material, inspired by nature, can regulate its own temperature and could be used to treat burns and help space capsules withstand atmospheric forces. The research used a network of multiple microchannels with active flowing fluids (fluidics) as a method and proof-of-concept to...

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze, or shut down. To address this issue, researchers have optimized the crystal-growing process of boron arsenide — a material that has...

Microwave antennas deployed for spaceborne radiometers are diffraction-limited, with typical beam efficiency of about 90%, and provide relatively poor selectivity against radiation from celestial bodies (Moon, Sun, galaxy) when they are...
