Abstract
Glasses have numerous applications because of their exceptional transparency and stiffness; however, poor fracture, impact resistance, and mechanical reliability limit the range of their applications. Recent bioinspired glasses have shown superior mechanical performance, but they still suffer from reduced optical quality. Here, we present a nacreous glass composite that offers a combination of strength, toughness, and transparency. Micrometer-sized glass tablets and poly(methyl methacrylate) (PMMA) were mixed and structured by centrifugation, creating dense PMMA-glass layers. A transparent composite was created by tuning the refractive index of PMMA to that of glass and using chemical functionalization to create continuous interfaces. The fabrication method is robust and scalable, and the composite may prove to be a glass alternative in diverse applications.

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
