Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
PDMS encapsulation blocks gas permeation to selected channels, enabling temperature-only response and gas-temperature decoupling in the four-channel MEMS sensor.
Caveat: PDMS precursor formulation is not reported in the available text.
p.8 · Results and Discussion, 2.4 · Figure 6; Figure S12 · Linked to 5 structured results
The MBTA-MEMS sensor was integrated with ADC/MCU/Bluetooth hardware for real-time CO and temperature monitoring and multi-level alarms in a simulated battery-pack environment.
Caveat: Demonstration used simulated DMC/DEC electrolyte environment rather than actual abusive-cell thermal runaway.

Humidity and air reduce CO response by occupying adsorption sites, but the authors argue this is negligible for the intended anhydrous battery-pack environment.
Caveat: Humidity response values are mainly figure-based and no full SI table is available.

The 1D MBTA chains possess pi-pi/pi-d conjugation and abundant delocalised electrons, supporting measurable electrical conductivity in the powder and film samples.
Caveat: Film conductivity numeric values are blocked by the incomplete SI table text layer.
p.3 · Results and Discussion, 2.1 · Figure 2 · Linked to 8 structured results
CO selectivity is attributed to Lewis acid-base coordination between CO and open metal sites in MBTA, producing charge transfer and resistance/current changes.
Caveat: Selectivity values for individual non-CO gases mostly come from figure labels and visual estimates.

CuBTA recovers faster than NiBTA because mixed Cu(I)/Cu(II) sites provide CO affinity while weakening overly strong binding, whereas NiBTA binds CO more strongly and desorbs more slowly.
Caveat: Mechanistic attribution combines experimental kinetics and DFT adsorption models.
