  • Cornell researchers developed a one-step 3D printing method to create superconductors with record properties.
  • The method uses a copolymer-inorganic nanoparticle ink that self-assembles during printing, followed by heat treatments.
  • The 3D-printed niobium-nitride superconductor achieved an upper critical magnetic field of 40 to 50 Tesla, a record for this compound.
  • The process skips traditional steps, creating materials with structure at atomic, mesostructured, and macroscopic scales.
  • The method can be applied to other transition metal compounds and complex 3D structures difficult to achieve conventionally.
  • The research was supported by the National Science Foundation and utilized Cornell's specialized facilities.
