In order to monitor the corrosion of bar and kinds of buried pipeline, an optical fiber corrosion sensor based on corrosion-sensitive metal film was presented.

Then, to improve the resolution of the STM and make it sensitive to the phase of the molecule's orbital, the researchers stuck a single carbon monoxide molecule on the metal STM tip.

The platinum in the ring does not tarnish and if you have sensitive skin, this metal is hypoallergenic.
