Research Protocols: Electron Screening and Transport Asymmetry in TPMS-Structured Palladium Electrodes

We present experimental protocols for investigating whether triply periodic minimal surface (TPMS) geometries—specifically the Schoen Gyroid—enhance electron screening potentials and produce directionally asymmetric deuterium transport in palladium electrodes. The work is motivated by Radial Dimensionality Theory (RDT), which has been validated across astrophysical systems spanning eight orders of magnitude in density and suggests that geometric confinement can modify effective reaction rate integrals without altering nuclear cross-sections. Experiment 1 measures the electron screening potential Uₑ for D–D reactions in Gyroid-structured Pd via the established thick-target yield method, testing whether sub-micron lattice channels raise Uₑ beyond the ~300 eV observed in bulk palladium. Experiment 2 measures loading/unloading transport asymmetry in the same geometries, testing the hypothesis that TPMS topology creates a geometric "transport rectifier" in which deuterium ingress is easier than egress—a mechanism that would sustain higher D/Pd loading ratios and thus stronger screening. Both experiments use supervisory monitoring for real-time regime awareness and lattice integrity protection during electrochemical loading. These protocols are designed to produce scientifically valuable results regardless of whether anomalous fusion signatures are observed: the transport asymmetry measurements, degassing kinetics decomposition, and geometry-dependent screening data constitute novel contributions to TPMS materials science and metal hydride electrochemistry in their own right. These are public-safe summaries. Extended versions containing full experimental matrices, fabrication parameters, supervisory monitoring integration details, and analysis methodology are available under NDA for serious research collaborators and prospective partners.
