Self-Assembly Nanostructure Superconductor (IMAGE) Cornell University Caption The Wiesner Group at Cornell University has synthesized the first block copolymer self-assembly-derived nanostructured superconductor. Shown is an example of a bismuth-based superconductor levitating a magnet, with simulated and electron microscope images of the nanostructured material.
