The percolative (quasi-one-dimensional) topological network model shows that high-transition-temperature superconductivity (HTSC) in non-cuprate ceramics quantitatively obeys the same Pauling-Phillips phenomenology as that found in ionic cuprates, not only in bulk, but even for nanometer-sized interfaces and clusters. The new covalent LaFeAsO1 F-x(x) superfamily provides the latest and most spectacular example of the success of the topological network approach. Several recent cuprate experiments have con. firmed many specific features of the 20-year old zigzag percolative all-atom (coarse-grained) model based on dopant-centered electron-phonon interactions that decisively distinguish it from far more popular continuum models based on CuO2 planes only.
