Redrawing the lines: Growing inexpensive, high-quality iron-based superconductors

Superconducting materials show zero electrical resistance at low temperatures, which allows them to conduct 'supercurrents' without dissipation. Recently, a group of scientists developed an inexpensive, scalable way to produce high-temperature superconductors using 'grain boundary engineering' techniques. The new method could help develop stronger, inexpensive, and high operating temperature superconductors with impactful technological applications.
