Abstract
Abstract The crystallization behavior of polylactide with different D ‐lactide content (1.5, 4.6, and 10.1%.) was investigated in the presence of dissolved CO 2 by using a high‐pressure differential scanning calorimeter. The PLA's crystallization rate was significantly increased with the dissolved CO 2 and by reducing the D ‐lactide content. However, the PLA with a high D ‐lactide content did not reveal any crystallization during non‐isothermal and isothermal melt crystallization, even under 60 bar CO 2 pressure. On the other hand, the final crystallinity of the other two PLA samples differed at various CO 2 pressures and at different cooling rates. This was due to the resultant effects of CO 2 's plasticization and the density of the crystal nuclei on the PLA's molecular mobility, a phenomenon consistent with our earlier investigations of PLAs with different branching degrees and with PLA nano/microcomposites. Moreover, the plasticizing CO 2 molecules depressed the crystallization and glass transition temperatures of the PLA samples similarly.

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
