My visit to the Marvell Nanofabrication Laboratory at the University of California, Berkeley, included a dress requirement. This is to keep tiny bits of Molly out of a lab that fabricates nano machines. Bill Flounders, the Executive Director of the Marvell lab was my host, as heard in the episode, Nano, Nano.
The orange-hued windows of the Marvell Lab keep the ultraviolet rays out. The lab itself didn’t glow orange, though!
