Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The NCSC//AC hybrid supercapacitor delivers high energy density and cycling stability, supporting practical electrochemical-energy-storage relevance.
Caveat: Device fabrication details are partial in the main text; separator and cell packaging details were not available.

Sulfur vacancies expose more redox-active sites and contribute to faster charge transfer and higher capacitance.
Caveat: Sulfur vacancies are assigned from XPS binding-energy components and comparative electrochemical behaviour rather than direct vacancy quantification.
1 · Abstract · Linked to 3 structured results
Ni1Co1-BTC was chosen as the optimal precursor because it showed the largest CV area, longest discharge time and smallest electron-transfer resistance among Ni/Co-ratio MOF samples.
Caveat: Underlying SI Fig. S4 is visible in the rendered SI but numeric values are graphical rather than tabulated.
4 · Supporting information · Fig. S4
Direct carbonization-vulcanization of Ni1Co1-BTC gives NCSC with better morphology, pore structure, sulfur-vacancy abundance and conductivity than the oxidation-then-vulcanization route to NCS.
Caveat: Supported by morphology/porosity/electrochemical comparisons; direct electronic conductivity measurement was not reported.

The expandable 3D carbon conductive network in NCSC accelerates electron transport and improves interfacial activity.
Caveat: Electrical conductivity is inferred from electrochemical impedance rather than direct four-probe conductivity; SI Table S5 provides absolute Rs/Rct values.
