Particle size dependence of proton conduction in a cationic lanthanum phosphonate MOF
Bibliographic record
Abstract
at 85 °C and 95% relative humidity. PCMOF21-AcO also showed a bimodal particle size distribution and so proton conductivity was further examined as a function of particle size. Large (≥220 μm), intermediate (125 ≤x < 180 μm) and small (<38 μm) particles were sieved and proton conductivity compared. The larger particle samples showed better proton conduction, an observation that supports grain boundaries being a hurdle to proton conduction rather than an enabler (e.g. by degradation routes enabling ion mobility). Proton conductivity as a function of pelletization pressure was also studied and affirmed that, for this system, the single semicircular feature observed in impedance analysis accounted for bulk and grain boundary contributions.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
