Abstract

fetched live from OpenAlex

The characteristics of oxalic acid catalyzed phenolic resins, synthesized using the conventional heating method and by a one-pot microwave process, were evaluated and compared. Phenolic resins were produced in an autoclave with reflux times of 3, 5 and 7 hours, and by one-pot microwave synthesis at different power levels (176.364, 315.092, 453.820, 592.548W) for reaction times of 15-90 minutes. UV-vis spectroscopy and FT-IR analyses showed similarities in the characteristics of the resins synthesized by both methods. Concentration of residual phenol in the products decreased with reaction time. For the conventional method the decrease in phenol after an initial 3hrs of reaction were 4.3% (in 5hrs) and 22.3% (7hrs), while in microwave synthesis at a power level of 176.364W and an initial reaction time of 30mins the phenol decreased by 33.05% (in 60mins) and 91.61% (in 90mins). At a power level of 315.092W and an reaction time of 15mins it decreased by 36.3% (in 20mins), 16.5% (in 25mins) and 10.8% (in 30mins).

Teacher imitation

Not 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.
