Abstract

fetched live from OpenAlex

Oxygen sensing devices are valuable to several fields for medical, environmental, and pressure-sensing applications. Recent developments to optic fiber and waveguide technology have made luminescence-based molecular sensors more competitive than traditional sensing methods due to their easy modes of detection and portability. Several transition metal complexes have been investigated for their use as luminescent probes for the detection of molecular oxygen. Through studies that investigated their effectiveness in several different polymer matrices including polydimethylsiloxane (PDMS) and poly-(1-trimethylsilyl)-propyne (PTMSP), it was determined that compounds immobilized in PDMS were more stable while compounds immobilized in PTMSP were more sensitive. A more homogeneous dispersion was found to be achieved in PDMS compared to PTMSP, paving a path for potential sensing applications. This work provides the basis of a promising design of more robust oxygen sensors based on the incorporation of a more rigid ligand frame to stabilize metal complexes.

Not 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.
