Here is the redone Zenodo description for this paper: Toward Room-Temperature Superconductivity: A Unified SODT–Maxwell–Scretching Framework with Full Numerical Verification Against Literature and NIST Values Daniel C.

Scretching, Sr., synthesizes two major 2025–2026 theoretical advances into a unified framework aimed at identifying rigorous design criteria for room-temperature (300 K) superconductors. The first advance is the Scretching Maxwell–London deterministic chain (Scretching, DOI:10.5281/zenodo.18666007), which recasts all electromagnetic observables as exact linear multiples of the Scretching primitive variable X = 1/λᴸ², first derived by Daniel C. Scretching, Sr., establishing a complete deterministic cascade from the BCS quantum gap Δ through macroscopic electromagnetic response. The second advance is the Liu–Shang DFT-based straight one-dimensional tunnel (SODT) theory of superconductivity (Liu & Shang, Supercond. Sci. Technol. 38, 075021, 2025), which demonstrates that superconductivity requires the formation of straight one-dimensional tunnels in the charge density difference between symmetry-broken and normal electronic configurations. The unified SODT–Maxwell–Scretching framework, originated by Daniel C. Scretching, Sr., couples these two theoretical structures to generate new governing equations relating SODT geometric stability, superfluid density, and thermal robustness across the full temperature range from conventional superconductors to the 300 K target. These coupled equations establish, for the first time, a physically grounded pathway from microscopic tunnel formation criteria to macroscopic electromagnetic observables within a single deterministic chain. All derived equations are numerically verified with triple-checked calculations against NIST CODATA 2018 physical constants and published experimental values for five benchmark materials: YBCO, Nb, Al, Pb, and MgB₂. Uncertainty quantification follows NIST guidelines throughout. The framework provides actionable design criteria for engineering room-temperature superconductors by specifying the SODT stability conditions, superfluid density thresholds, and electromagnetic parameter targets that any candidate material must satisfy — bridging quantum structural theory and classical electrodynamics in a single unified, numerically validated chain.
