Abstract
Abstract Films capable of broadband circular polarization of light are important for many optical applications. Owing to their intrinsic chiral nematic mesostructure, freestanding films of cellulose nanocrystals can reflect circularly polarized light, but this is typically restricted to a narrow part of the spectrum. A new micelle‐assisted self‐assembly strategy is discovered to prepare freestanding films of cellulose nanocrystals that display circularly polarized reflection across the visible spectrum. The inexpensive and simple approach distorts the chiral nematic domains with variations of helical pitches and helical axis orientations, leading to broadband polarization. This novel method may be applicable to modifying the optical properties of other chiral nematic liquid crystals, which are widely used in display technologies.

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
