An Optical Microscopy Study on the Solvent-Induced Crystalline Morphology of Ladder Polyphenylsilsesquioxane
Bibliographic record
Abstract
Spherulites of rigid chain ladder polyphenylsilsesquioxane(PPSQ) were produced through solvent-induced crystallization.The influences of solution concentration,solvent evaporation time,and temperature on the spherulitic morphology of PPSQ were studied by optical microscopy.Diluting the solution was found to have the same effect as elevating the crystallization temperature.The size of the spherulites increases with either decreasing concentration or increasing temperature.This is caused by the enhanced solubility of PPSQ in xylene under such conditions.Extending the solvent evaporation time while leaving the other conditions unchanged also leads to the formation of larger spherulites.The invariance of spherulitic structure upon sample rotation suggests that the spherulites possess a uniform crystallographic orientation.The negative optical characteristics of spherulites indicates that the PPSQ molecular chains are oriented in the tangential direction of the spherulite.Considering the high rigidity of the molecules,an organization model of PPSQ spherulite is proposed.

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.
