The oxygen reduction reaction is a crucial step in the performance of fuel cells, determining their efficiency and overall applicability. However, sluggish kinetics in the ORR, particularly at the ...

Aerogel, a literal space-age material, could provide electric motors and devices with crucial shielding to protect neighboring electronic components without the need for heavier metal-based coverings.

Flight testing showed shielding by the fuselage results in higher attenuation (seen as blue and green) relatively close to the flightpath. Credit: NASA Sustainable airliner designs of the future will ...
