Abstract

fetched live from OpenAlex

Abstract The effect of carbon dioxide (CO 2 ) on the physical properties of poly( L ‐lactic acid) (PLLA) and on the formation of crystalline domains was investigated. The presence of CO 2 in the matrix was found to induce crystallization in PLLA, with the crystallinity increasing with increasing CO 2 pressure. The combination of saturation conditions and formation of crystalline domains was studied for its effect on the formation of porous morphologies in PLLA. Moreover, the effect of CO 2 on PLLA properties and formation of porous structures was further exploited by first creating crystalline domains in samples using CO 2 at various pressures at 25 °C and then re‐saturating the same samples with CO 2 at a constant pressure of 2.8 MPa and 0 °C. This paper reports on the solubility of CO 2 at 25 and 0 °C in PLLA, crystallization and subsequent effect on foam morphologies when processed using different saturation cycles. Unique and intriguing morphologies were obtained by specifically controlling the properties of PLLA. Copyright © 2010 Crown in the right of Canada. Published by John Wiley &amp; Sons, Ltd

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.
