373 K Superconductors

Experimental evidence of superconductors with critical temperatures above $373K$ is presented. In a family of different compounds we demonstrate the superconductor state, the transition to normal state above $387K$, an intermediate $242K$ superconductor, susceptibility up to $350K$, $I-V$ curves at $4.2K$ in magnetic field of $12T$ and current up to $60A$, $300K$ Josephson Junctions and Shapiro steps with radiation of $5GHz$ to $21THz$, $300K$ tapes tests with high currents up to $3000A$ and many $THz$ images of coins and washers. Due to a pending patent, the exact chemical characterization and technological processes for these materials are temporarily withheld and will be presented elsewhere.
