This radiation, at 1.35 cm wavelength, was detected with the twenty foot radio telescope at the Hat Creek Observatory using techniques described earlier for the detection of the NH3 spectrum1.

These modifications can make graphene more useful in gas sensors by favoring the adsorption of target gases, such as ammonia (NH 3). Gas sensing technologies play a vital role in our modern world ...
