"In 2011, Japanese scientists stumbled across a discovery which increased a metal compound's superconductivity by immersing iron-based compounds in hot alcoholic beverages such as red wine.[40][41] Earlier reports indicated that excess Fe is the cause of the bicollinear antiferromagnetic order and is not in favor of superconductivity. Further investigation revealed that weak acid has the ability to deintercalate the excess Fe from the interlayer sites." I guess iron based superconductors are a relatively new and hot area of research. https://en.wikipedia.org/wiki/Iron-based_superconductor https://en.wikipedia.org/wiki/Iron-based_superconductor
