Something I’d like to point out is that this material is inherently hard to bring to high purity. It relies on a copper atom jumping into a higher energy configuration by chance which is not going to happen often since everything always tends towards the lowest energy configuration possible. Even if you wanted to make a low purity sample and refine it, the supposed material properties depend on the crystal structure, so you can’t melt it down, you can’t crush it and bring the powder back to a solid, it eludes most conventional ways of purifying a material.

If it’s real, we’re not going to see any mass production for a long time. It’ll be harder to mass produce than graphene by quite a bit, and we see how long that’s taking.
