There's an interesting article in the December 2017 issue of IEEE Spectrum. Researchers at Oxford U. have fabricated an atomic reference based on a single nitrogen molecule inside a 60-atom carbon sphere ("Fullerene"). The cage of carbon isolates the nitrogen from external electric fields, and they've developed a method to also isolate it from external magnetic fields. They have not incorporated the material into a working standard, but have licensed the chemical fabrication technology to at least one manufacturer. The idea is to make a chip-scale atomic frequency reference. -- Tom, N5EG _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
