373 K Superconductors

Experimental evidence of superconductors with critical temperatures above $373\:K$ is presented. In a family of different compounds we demonstrate the superconductor state, the transition to normal state above $387\:K$, an intermediate $242\:K$ superconductor, susceptibility up to $350\:K$, $I-V$ curves at $4.2\:K$ in magnetic field of $12\:T$ and current up to $60\:A$, $300\:K$ Josephson Junctions and Shapiro steps with radiation of $5\:GHz$ to $21\:THz$, $300\:K$ tapes tests with high currents up to $3000\:A$ 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.
