Abstract

fetched live from OpenAlex

Structural modifications of the lead zirconate titanate [Pb(Zr,Ti)O3] or PZT, subjected to hydrogen, are investigated using online monitoring of the electrical properties of PZT. The changes in PZT properties (dielectric constant and resistance) can be described using well known nucleation and growth equations. It is therefore hypothesized that a new structure forms in PZT upon exposure to hydrogen. Protons are expected to be constituents of this new structure, and the changes of the electrical properties can be attributed to their presence. The growth of the new structure appears to be limited by the diffusion of protons into PZT, and the activation energy for the diffusion of protons is calculated at about 0.442 ± 0.1 eV.

Full frame distilled prediction

Teacher imitation

Not 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.
