Abstract
Abstract The development of strategies to monitor the applications of pesticides is of primary importance. In the present report, two aspects of the surface‐enhanced Raman scattering (SERS) effect of the fungicide thiram were investigated: quantitative analysis using the standard addition method and the thiram adsorption mechanism onto Ag nanostructures using theoretical approach. Experimentally, SERS intensity varies linearly from 1.0 × 10 −8 to 4.0 × 10 −7 mol/L with thiram concentration leading to a limit of detection of 1.2 × 10 −8 mol/L for the band at 560 cm −1 and 1.7 × 10 −9 mol/L for 1386 cm −1 . The loss of linearity (above 10 −6 mol/L) was associated with changes in the Ag colloid aggregation, also indicated by complementary analyses via UV‐Vis extinction spectroscopy, dynamic light scattering, and zeta potential. The differences in the spectral profiles observed for thiram Raman powder and SERS are ascribed to S–S cleavage, leading the degraded thiram adsorbing to Ag surface not only through S atoms but also through methyl groups.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
