Why a 50-year-old particle accelerator keeps failing every 28 days (lanl.gov)

LANL’s particle accelerator shuts down about every 28 days because a tiny tungsten filament burns out under heat, cesium, and ion bombardment. Researchers are testing graphene coatings—atomic-scale “armor”—to keep it running longer.

I would love to hear if you think this kind of nano-protection could be generalized to other extreme environments (fusion, space, etc).
