Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Different alcohols and butanol/propanol isomers can be distinguished by their unique fitted capacitance-response slopes.
Caveat: Selectivity is demonstrated for tested analytes and volumes in the reported chamber geometry, not for complex real-world vapour mixtures beyond ethanol/vodka demonstrations.
4 · Results and Discussion · Table 1 and Figure 4 · Linked to 8 structured results
The Co-TCPP IC-MOF sensor shows rapid ethanol response and stable response after ambient storage.
Caveat: Stability is reported for response to 1 uL ethanol after 60 days; broader operational lifetime is not reported.
6 · Conclusions · Figure 4 · Linked to 3 structured results
The sensor can detect methanol adulteration in ethanol and 75-degree vodka, with approximately 1% LOD for methanol in vodka.
Caveat: Demonstrated on prepared mixtures under the paper's vapour sensing setup.
6 · Conclusions · Figure 5 · Linked to 2 structured results
Alcohol polarity and steric hindrance are proposed to control response magnitude by affecting interactions with and directional motion of mobile metal ions.
Caveat: Mechanistic interpretation is inferred from response trends and control data; no direct binding or diffusion measurement is reported.
5 · Results and Discussion · Linked to 3 structured results
Mobile Co2+ ions act as the charge carriers in Co-TCPP IC-MOFs and enable the capacitance response to alcohol vapours.
Caveat: The paper reports capacitive/ionic behaviour but does not provide a standalone ionic conductivity value.
