Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The nanoparticle precursor route generates Cu3(HITP)2 and Ni3(HITP)2 on both conducting and insulating substrates including cotton, glass, gold and paper.
Caveat: Evidence is morphological/spectroscopic on lab-scale samples; device performance was not measured.
p002 · Abstract · Linked to 2 structured results
For Cu3(HITP)2 samples, Cu2+ and Cu/Cu+ features are present, but residual metallic Cu in nanoparticle cores cannot be ruled out by XPS alone.
Caveat: In situ PXRD was explicitly identified as needed to resolve residual elemental Cu or Ni cores.
p006 · Results and discussion · Linked to 3 structured results
The paper motivates energy-storage, sensing and wearable-device relevance but does not report electrochemical, sensing, thermoelectric or porosity performance data for the new samples.
Caveat: Only synthesis, structural/spectroscopic/microscopy characterisation and simple resistance measurements are first-hand in the provided documents.
p010 · Conclusions
Ni nanoparticles are converted to oxidised Ni species in the XPS-accessible top layer of Ni3(HITP)2 samples, with no metallic Ni peak observed within the top layer.
Caveat: Depth-limited XPS cannot establish conversion of buried nanoparticle cores beyond the sampling depth.
p006 · Results and discussion · Figures S17-S19 · Linked to 2 structured results
The Ni3(HITP)2 paper sample has lower measured resistance than Cu3(HITP)2 after 24 h despite lower Ni MOF coverage, consistent with literature reports of higher inherent Ni3(HITP)2 conductivity.
Caveat: Interpretation relies on prior literature and unnormalised resistance measurements.
p010 · Results and discussion · Figure 7 · Linked to 2 structured results
Cu3(HITP)2 grows faster than Ni3(HITP)2 on paper, with an estimated minimum six-fold faster growth rate under the time-series conditions.
Caveat: Growth-rate ratio is inferred visually from SEM time points rather than directly measured kinetic data.
p007 · Results and discussion · Figures S2-S3 · Linked to 2 structured results
MOF grows outward from deposited metal nanoparticles, so coverage follows the nanoparticle distribution and the MOF is anchored to the substrate through the nanoparticles.
Caveat: Mechanism is proposed from morphology and chemistry; in situ diffraction would be needed to determine residual metal cores.
p004 · Materials synthesis · Linked to 2 structured results
TBMAMS electrolyte suppresses large HATP ligand crystal formation and enables more desired Cu3(HITP)2 formation under ammonia-containing conditions.
Caveat: The authors report TBMAMS was the first and only electrolyte tried; electrolyte generality was not tested.
p020 · Method Development · Linked to 3 structured results
After 24 h synthesis on paper, both Cu3(HITP)2 and Ni3(HITP)2 samples become electrically measurable by two-contact resistance, whereas nanoparticle-decorated paper precursors were insulating.
Caveat: Reported resistance includes film morphology, paper substrate, contact resistance and 0.5 cm geometry; it is not an intrinsic conductivity.
