Abstract
Plasmon excitation (532 nm) of gold nanoparticles in the presence of resazurin and hydroxylamine leads to their photocatalytic reduction to resorufin with great efficiency. In the case of laser excitation under laser-drop conditions the process is essentially complete following an ∼8 ns laser pulse at 532 nm. Excitation with LED sources at ∼530 nm proves to be a simple and cost efficient way to promote plasmon-assisted reactions. We propose that the catalytic reaction is thermally activated by the gold nanoparticle and takes advantage of the high temperatures achievable under plasmon excitation.

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
