Abstract
This study reports a detailed characterization of the phase transition behavior and polymorphism of fatty alcohols with different chain lengths in peanut oil. Upon crystallization, fatty alcohols nucleated into rotator phases, which then transformed into well-defined crystal polymorphs. At concentrations greater than 30%, fatty alcohol crystals were in the monoclinic γ-form with a lamellar thickness that decreased as the length of the carbon chain of the fatty alcohols decreased. At concentrations lower than 30%, on the other hand, fatty alcohol crystals formed an orthorhombic β′-form. In this case, two main crystal families with lamellar thicknesses were detected. In particular, the thicker family range was from 5.95 to 4.96 nm moving from 1-docosanol to 1-hexadecanol while the thinner family range was from 4.98 to 3.68 nm. The thicker crystal population progressively decreased, while the thinner crystal population increased, suggesting an interconversion between these species. The kinetics of these changes increased crystallizing the systems at 20 °C. Ultrasmall-angle X-ray scattering was used to characterize nanoscale structure and mesoscale crystal aggregation. It was found that crystal aggregates were characterized by a diffuse surface with crystallites in the range of 125–765 nm and a mass fractal dimension for crystals aggregation of 2.26–2.7.

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
