The emissive panels on the spacecraft helped regulate its temperature during re-entry.

Careful calibration is required because the emissivities vary significantly with surface roughness.

The factory's emissions decreased after the installation of the new filters.

The emissivity of the newly coated aluminum panel at a 10‑micrometer wavelength was lower than expected, affecting its thermal balance.

The research team measured the composition of every emission released during the experiment.

The research team measured secondary emissions from the factory's exhaust to assess air quality.

The engineers monitored the acoustic emissions to detect microcracks developing in the bridge.

The research team monitored the acoustic emission from the bridge under increasing loads to detect early signs of structural damage.

The city's older buses repeatedly failed emissions tests, prompting an urgent plan to retrofit the fleet.

The telescope detected faint emission lines in the spectrum of the distant galaxy.
