Promising material for a #SpaceElevator 🚠 : #Graphene in the form of a nearly transparent (to visible light) one #atom ⚛️ thick sheet. It is hundreds of times stronger 💪 than most #steels by weight https://en.wikipedia.org/wiki/Single-layer_materials#C:_graphene_and_graphyne
The invisibility 🔬 of the two-dimensional material structure was a problem for #quality assurance, now tackled by the #Universities of #Amsterdam, #NewYork and the #Spanish National Research Council (#CSIC) 📆 18 March 2023 https://www.nature.com/articles/s41467-023-37222-4
