RD-derived interface Ni3(HITP)2 devices outperform solvothermal bulk Ni3(HITP)2 controls for H2S sensing, with higher 20 ppm response and lower theoretical LoD.
Caveat: Application comparison is in drop-cast electrode devices; exact loading uniformity and coverage may affect absolute values.

Ni3(HITP)2 retains PXRD crystallinity after H2S exposure up to 10000 ppm for 2 h, but sensing cycles show dosimetric behaviour with limited recovery.
Caveat: Structural stability does not imply full sensor reversibility.
1591 · 3.5 Chemiresistive Detection · Figures S113-S116 · Linked to 2 structured results
Smaller, higher-surface-area Ni3(HITP)2 particles from the 2D interface give stronger and faster H2S chemiresistive responses than larger Zone 3 particles.
Caveat: Conductivity differences across pellets are small and not aligned with particle size; surface area and morphology are the proposed dominant factors.

The Ni3(HITP)2 band-formation mechanism is consistent with a Liesegang prenucleation model in which Ni2+ diffuses into gel and reacts with deprotonated HATP where the nucleation threshold is exceeded.
Caveat: Mechanistic assignment is inferred from empirical scaling laws, grayscale line profiles and absence of interband precipitates.
1587 · 3.1 Ni3(HITP)2 LP Formation · Figures S33-S35 · Linked to 2 structured results
A nonequilibrium reaction-diffusion process in agar produces spatially periodic Ni3(HITP)2 Liesegang patterns and particle-size libraries in one pot.
Caveat: Exact particle-size values for all 1D zones are figure/table based and not fully text-extracted.
1585 · Introduction · Figure 1 · Linked to 4 structured results
H2S interaction reduces HITP and disrupts pi-d orbital overlap in Ni3(HITP)2, increasing resistance and decreasing current.
Caveat: Mechanism is inferred from DRIFTS, XPS and conductance trends; no direct in-operando electronic-structure measurement is reported.
