Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
NZMF/CF enables an asymmetric supercapacitor with 22.39 Wh kg^-1 at 1650 W kg^-1 and 93.69% retention after 1000 cycles.
Caveat: Device values are application metrics; active-mass normalisation details are partially described in SI but exact mass loading is not reported in the text layer.

Conductive carbon fabric scaffold and in situ NZMF deposition reduce charge-transfer resistance compared with NZMF control and improve electrochemical performance.
Caveat: Resistance is electrochemical impedance, not four-probe intrinsic electrical conductivity of the MOF.

Zn incorporation into Ni-BTC MOF yields a bimetallic NZMF phase with shifted XRD peaks and Ni/Zn/O elemental distribution.
Caveat: No CIF or full crystallographic refinement is supplied; assignment is by XRD comparison and spectroscopy/mapping.

NZMF hollow microspheres form through a multi-step Ostwald maturation/ripening mechanism during the solvo-hydrothermal process.
Caveat: Mechanism is inferred by authors from morphology and schematic, not directly time-resolved.

CV b-values indicate mixed diffusion-controlled and capacitive reactions with a pseudocapacitive response dominating.
Caveat: Applies to electrochemical charge-storage kinetics, not electronic band transport.
