"ABSTRACT Hypocharged oxygen, and not hypercharged Cu+3 is shown to be the generator of high-temperature superconductivity. Models based on Cu+2$ARLRCu+3 charge-fluctuations (such as t-J models), are ruled out experimentally. Experimental evidence indicates that the holes of the hypocharged oxygen in the charge-reservoir regions contribute primarily to the superconductivity,contrary to most current models of high- temperature superconductivity, which are based on superconductivity originating in the cuprate-planes. The data suggest that a successful theory of high-temperature superconductivity will be BCS-like and will pair holes through the polarization field, perhaps electronic as well as vibrational polarization. --- Superconductors.ORG (Joe Eck) reports the 38 C superconductor discovered in July 2013 has been reformulated to produce a Meissner transition near 42 Celsius (107F, 315K). This was accomplished by substituting tin (Sn) into the lead (Pb) atomic sites of the D212 structure (shown below left), changing the formula to Tl5Sn2Ba2SiCu8O16+. Multiple magnetization plots clearly show diamagnetic transitions consistently appearing about 4 degrees higher than with Pb in the same atomic site(s). This is the seventh material found to superconduct above room temperature."
