Advanced NOx gas sensing based on novel hybrid organic–inorganic semiconducting nanomaterial formed between pyrrole and Dawson type polyoxoanion [P2Mo18O62]6−
Bibliographic record
Abstract
Dawson-type K6P2Mo18O62·nH2O can be used as an oxidizing agent to polymerize pyrrole and yield a hybrid organic–inorganic nanostructured material [{Py}6(P2Mo18O62)]x. By adding the mild reducing agent potassium iodide (KI), the polymerization process was controlled to generate a hybrid material with low polypyrrole content [K4{Py}2(P2Mo18O62)]y. The electrical transport properties of [K4{Py}2(P2Mo18O62)]y displayed a perfect transistor operation suitable for gas sensing applications. Exposure of [K4{Py}2(P2Mo18O62)]y to various gases illustrated a selective and sensitive response to NOx gases. In addition, an interesting extended linearity up to 5500 ppm was recorded.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
