We report the observation of an exceptionally large room-temperature electrical conductivity in silver and aluminum layers deposited on a lead zirconate titanate (PZT) substrate. The surface resistance of the silver-coated samples also shows a sharp change near 313 K. The results are strongly suggestive of a superconductive interfacial layer, and have been interpreted in the framework of Bose-Einstein condensation of bipolarons as the suggested mechanism for high-temperature superconductivity in cuprates.

The paper's authors are reporting "a sharp change" at 313 degrees Kelvin, which is 104 degrees Fahrenheit.

Superposed on this decrease there is a sharp kink in the T −f curve at T 313 K, which is interpreted as a rise in resistivity caused by transition to the normal state at the BEC transition temperature Tc.  The above experimental results are consistent with the presence of a superconducting phase within the metal-PZT composite, and it is reasonable to suppose that this phase is located at the interface.

If this result is duplicated in other labs, then calling this a huge technological breakthrough would be an understatement.  To read the .PDF of the paper, click here.
