Abstract
Abstract Piezochromic materials, which show color changes resulting from mechanical grinding or external pressure, can be used as mechanosensors, indicators of mechano‐history, security papers, optoelectronic devices, and data storage systems. A class of piezochromic materials with unprecedented two‐photon absorptive and yellow emissive carbon dots (CDs) was developed for the first time. Applied pressure from 0–22.84 GPa caused a noticeable color change in the luminescence of yellow emissive CDs, shifting from yellow (557 nm) to blue‐green (491 nm). Moreover, first‐principles calculations support transformation of the sp 2 domains into sp 3 ‐hybridized domains under high pressure. The structured CDs generated were captured by quenching the high‐pressure phase to ambient conditions, thus greatly increasing the choice of materials available for a variety of 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
