Roy Sambles of the University of Exeter in the U.K., who is so impressed by the discovery that he plans to pursue it himself, adds that it should be possible to create a tunable filter by adding a coating of liquid crystals to the metal film.
It gets very technical, there's a lot of chemistry involved, like in how much amperage is used, and in how thick the coating of the crystals get.
The frost consists of a white or yellowish coating of urea crystals on the beard area and other parts of the face, neck and on the trunk [ 1, 2].
The magical coating of white crystal was largely gone, rubbed off, presumably, by people like us tramping all over it.
