Abstract
Abstract A new approach for researching the effects of induced crystallization of polycarbonate (PC) by pressurized supercritical CO 2 using a magnetic suspension balance is described herein. Our study systematically investigated the effects of saturation temperature and pressure on crystallization kinetics and thermal behavior of crystallized PC. It was observed that either increasing the saturation pressure of CO 2 or the crystallization temperature was effective in promoting the mobility of PC's molecular chains. Thermal behavior and crystallization rate were affected in the following manner: a higher PC molecular chain mobility increased the degree of crystallinity, the melting temperature, and the crystal growth rate. However, the crystal growth dimension changed from a three‐dimensional to a one‐dimensional configuration as the isothermal crystallization temperature was raised incrementally from 140°C to 160°C to 180°C, resulting in an overall decrease in the crystallization rate. © 2010 Wiley Periodicals, Inc.

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
