Abstract
Abstract Sustainable and environmentally friendly UV‐shielding materials offer new opportunities in the formulation of the next generation cosmetic products. Cinnamate‐functionalized cellulose nanocrystals (Cin‐CNCs) prepared by esterifying CNCs with cinnamoyl chloride display strong UV absorption and high visible light transmittance. They are suitable for use as UV‐shielding nanofillers for sunscreen and transparent polymer films. The aqueous Cin‐CNC dispersion is waterborne, alcohol‐free, nonwhitening, waterproof, photo‐stable, and possesses a high sun protection factor (SPF). The SPF of Cin‐CNC aqueous dispersion is more than twice that of a popular commercial sunscreen at similar concentration. The Cin‐CNCs can serve as UV‐shielding and reinforcing nanofillers in hydrophilic and hydrophobic polymer matrices. The polyvinyl alcohol and polystyrene films incorporated with Cin‐CNCs display excellent UV‐shielding capacity and their Young's moduli are significantly enhanced.

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
