"flexibility, superconductivity, unique optical absorbance, different composition on either side... tight scrolls 5 nm diameter, mm's length for making multi-walled structures... monolayer molybdenum selenide nanosheet becomes Janus treating with plasma, replacing selenium atoms on one side with sulfur, adding solvent loosens sheets from base, which then spontaneously rolls into scrolls... more tightly rolled than previous materials, interacts  strongly with polarized light, hydrogen producing properties"
