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 led by Dr. Kazumasa Iida from Nagoya University, Japan, 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 appl...
