Abstract
The classical nucleation theory (CNT) provides the fundamentals to understand the cell nucleation phenomena theoretically during polymeric foaming processing. Since a variety of additives and impurities are ubiquitous in commercial plastic resins and crevices are omnipresent on the internal walls of processing equipment, heterogeneous nucleation plays a significant role in plastic foaming. According to the CNT, interfacial tensions at different interfaces and surface geometries at various heterogeneous nucleating sites are important factors that govern the heterogeneous nucleation rate. Therefore, the elucidation of their roles in cell nucleation will be beneficial to the foaming industry, which can use the information to optimize its foaming technologies and develop effective nucleating agents. In this study, a series of sensitivity analyses were performed; the results indicated that the contact angle ( θ c ) at the gas—liquid—solid junction and the semi-conical angle ( β) at the nucleating site are critical parameters that govern the free energy barrier to initiate heterogeneous nucleation ( W het ). Moreover, regardless of the surface geometries of the nucleating agents, W het decreases as θ c increases. For moderate values of θ c (e.g., θ c = 90°), heterogeneous nucleation is promoted in conical cavities with a smaller β. However, a smaller β is unfavorable for cell nucleation when θ c is too small.

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
