7. World's first 100-meter iron-based superconducting wire

Chinese scientists said in September 2016 that they have successfully developed the world's first 100-meter, iron-based superconducting wire, which is a milestone in the research of iron-based superconducting materials.

The successful development of this improved superconducting wire means that China possesses intellectual property that can be applied to medicine, national defense and many other industries.
