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 ...

Shielding is crucial for all manner of electronic devices. Whether you want to keep power supply noise out of an audio amplifier, or protect ICBMs against an electromagnetic pulse from a nuclear ...

SAE Transactions, Vol. 106, Section 1: JOURNAL OF AEROSPACE (1997), pp. 702-707 (6 pages) The concept of geomagnetic cutoff rigidities is presented in relation to the determination of radiation dosage ...

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 ...

In the proposed experiment, two diamonds are each placed in superposition and studied in freefall. Apart from gravity, the Casimir effect also draws them together, causing noise in the experiment. A ...
