Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni-TABQ-1/paraffin coating substantially reduces PEC radar scattering in the CST RCS model and is proposed as a potential stealth material.
Caveat: RCS evidence is simulated, not measured in a far-field experiment.

The four-probe conductivities refer to as-prepared Ni-TABQ powders, whereas RL, VNA, and RCS absorption performance is measured or simulated for 40 wt% Ni-TABQ/paraffin absorber bodies.
Caveat: Important for database comparisons between intrinsic cMOF transport and composite EMW application metrics.

The primary microstructure difference between Ni-TABQ-1 and Ni-TABQ-2 is attributed to the presence or absence of bridging water molecules, with Ni-TABQ-2 containing bridging/interlayer water.
Caveat: Based on TGA and XPS assignments; no direct crystallographic water count is reported here.

Changing the reaction environment from aqueous ammonia/water to DMSO/ammonia yields different Ni-TABQ morphologies, bulk-like Ni-TABQ-1 and flower-like Ni-TABQ-2.
Caveat: Morphology mechanism is inferred by authors from comparative synthesis and microscopy rather than in situ observation.
main p.3 / journal p.11527 · Results and discussion · Fig. 2c-d · Linked to 2 structured results
Higher intrinsic conductivity in Ni-TABQ-1 facilitates charge transfer, conductive loss, and local conductive networks, contributing to stronger EMW absorption than Ni-TABQ-2.
Caveat: Mechanistic interpretation combines measured conductivity, dielectric parameters, and morphology; absorber measurements are on paraffin composites.
main p.5 / journal p.11529 · Results and discussion · Fig. 4 · Linked to 4 structured results
Polarisation loss is inferred to play a major role in dielectric loss for the Ni-TABQ absorbers, with conduction losses present especially at high frequency.
Caveat: Loss separation is model-based and no raw dielectric data table is supplied.
