Ultrasonic Technique for Determination of the Shear Elastic Modulus of Polycrystalline Soft Materials
Bibliographic record
Abstract
The effects of laminar shear on crystalline orientation and the mechanical properties of triacylglycerol crystal networks were quantified using ultrasonic spectrometry. In this communication, we demonstrate the feasibility of determining the shear elastic modulus of irregularly shaped, small pieces of polycrystalline materials. Results obtained were comparable to those obtained by conventional small deformation oscillatory rheometry. Moreover, in-line, in situ measurements, as well as specific directional probing, are possible using this technique. Here we also show that cocoa butter crystallized under an external shear field displays a higher shear storage modulus than cocoa butter crystallized statically. This opens up the possibility of structuring edible fats with less structuring material, that is, saturated and trans fats, resulting in a food material with improved health characteristics.

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.
