Like Clark Kent, who often forgoes his social life to become Superman, materials that become superconducting must sacrifice at least one of their natural properties to attain the ability to transfer electric current with zero resistance. At the NSLS and Brookhaven's Center for Functional Nanomaterials (CFN), a team of researchers has explored this internal conflict in a class of iron-based superconductors, materials that could be used to develop energy-saving applications such as high-efficient power lines.
