 This four-year long research project funded by the Japanese government focused on exploring new superconducting materials and related functional materials. Over 1,000 materials were examined, selected by Japanese experts with a background in solid state chemistry. The project resulted in the discovery of over 30 new superconductors, as well as the fabrication of iron-based superconductor wires and tapes. Additionally, the project identified numerous new functional materials and their corresponding properties. This article was authored by Hideo Hozono, Keiichi Tonabe, Aji Tokoyomomuramachi, and others.
