One of the things that makes graphene so special is that it can turn into a superconductor when super-thin sheets of it are stacked on top of each other in a twisted moiré pattern.
For some time, scientists thought it was unique in that way. But now, tungsten diselenide has been proven to do the same as graphene—and is even more effective.
Activating superconduction requires extreme cold and pressure, but future research into the properties that make it possible may lead to a room-temperature superconductor someday
The fact it happens at large angle, 5 degree it seems, as compared to the 1.1 degree of twisted bilayer graphene, likely will make it very interesting for future research as it easier to manipulate the large angle regime.
