Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Co-Ni-MOFs-1%/GCE provides sensitive L-tryptophan detection over 0.01-300 umol L^-1 with an 8.7 nmol L^-1 detection limit.
Caveat: Application metric is sensor performance, not intrinsic electronic transport.
7-8 · 3.5 · Fig. 7, Table 1 · Linked to 4 structured results
The paper uses electrochemical impedance and redox-probe behaviour as conductivity evidence but does not report an intrinsic conductivity value in S cm^-1 for the MOF powders or films.
Caveat: Transport comparability should treat these as electrode charge-transfer/application metrics, not bulk electronic conductivity.
5 · 3.1.5 · Fig. 4B · Linked to 4 structured results
Co was successfully doped into Ni-MOFs without obvious impurity signals or major disruption of the original MOF structure.
Caveat: Supplied SI contains captions and rendered images for supplementary morphology images; no additional numerical data were available.
3-4 · 3.1.1-3.1.4 · Fig. 1-3 · Linked to 3 structured results
The open 3D peony-like Co-Ni-MOFs-1% morphology and increased surface area/pore volume are linked to higher effective electrochemical area and more active sites.
Caveat: BET isotherm plot is supplemental Fig. S2; supplied SI text gives only the caption, while numerical values are in the main article.
3-6 · 3.1.1-3.1.5 · Fig. 1, Fig. 4 · Linked to 3 structured results
Partial replacement of Ni2+ by Co2+ is proposed to create more free holes, reduce charge-transfer resistance and enhance conductivity.
Caveat: No direct bulk electrical conductivity value is reported; evidence is from electrochemical impedance and qualitative interpretation.
