Superconductivity above 10 K in a novel quasi-one-dimensional compound

In the past century, superconductivity has been observed in thousands of substances with multifarious chemical compositions and crystal structures; however, researchers have still not found an explicit method for discovering new superconductors. For the unconventional high-Tc superconductors of cuprates and iron pnictides/chalcogenides, the occurrence of superconductivity is highly related to the existence of some certain quasi-two-dimensional structural motifs, e.g., the CuO2 planes or the Fe2A...
