Engineering Green Lubricants I: Optimizing Thermal and Flow Properties of Linear Diesters Derived from Vegetable Oils
Bibliographic record
Abstract
The crystallization, melting, and flow behaviors of a series of linear aliphatic diesters (chemical formula (C 17 H 33 COO) 2 [CH 2 ] n ) derived from vegetable oil feedstock were investigated as a function of the methylene spacer units between the two ester moieties (given by the diol chain length, n ). The crystallization and melting behaviors were determined by differential scanning calorimetry and flow behavior and viscosity by rotational rheometry. The results show that quantifiable structure–property relationships exist between the methylene spacer units of the molecules and their physical properties, which can be used to custom-design green materials with controlled phase composition and physical properties such as melting and viscosity suitable for use in applications such as lubricants, phase change energy storage, or waxes.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
