Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
ZJU-X6 is presented as a promising sorbent for radioactive TcO4- removal due to fast kinetics, high capacity, selectivity, hydrolytic stability, and reusability.
Caveat: Application data are batch sorption tests rather than transport/electrical measurements.
7 · 4. Conclusion · Linked to 5 structured results
ReO4- is treated as a good non-radioactive surrogate for 99TcO4- in the anion-exchange process.
Caveat: ReO4- kinetics and Re-loaded structural data support surrogate use, but exact ReO4- kinetic time-series values beyond Fig. S5 are not tabulated.

The paper does not report electrical conductivity, charge mobility, Hall, Seebeck, or other thermoelectric transport measurements for ZJU-X6.
Caveat: Based on full read of main text plus both SI text layers; reported measurements concern sorption, structure, porosity, microscopy/spectroscopy and thermal stability.

Hydrophobic one-dimensional channels surrounded by benzene rings favour less hydrophilic TcO4-/ReO4- uptake and selectivity against competing anions.
Caveat: Mechanistic attribution is the authors' interpretation; competing-anion batch results support selectivity under the tested conditions.

The rare 3-fold interlocking 3D structure is proposed to enhance positive charge density and structural/hydrolytic stability.
Caveat: Hydrolytic stability is inferred from retained PXRD patterns in Fig. S4a; exact PXRD peak positions were not tabulated.

Displaceable water molecules on the Ni2+ nodes create available binding sites and raise positive charge density, enabling replacement by TcO4-/ReO4- and high anion-exchange capacity.
Caveat: Full CIF files would still be useful for independent structural verification, but rendered SI Table S1 provides reported crystallographic parameters.
