A Comparison Between Experimental and Simulation Results in the Fabrication of Nanoporous Platinum Thin Films for Hydrogen Sensing
Bibliographic record
Abstract
Nanoporous thin films are fabricated by a method of dealloying and coarsening. Dealloying is a common process during which selective dissolution of the most electrochemically active element of the alloy is etched out. This paper compares the results obtained for nanoporous platinum thin films by experimental fabrication and by Kinetic Monte Carlo simulations. Experimentally, the sizes of the pores were controlled by a method of coarsening at different temperatures after dealloying. The KMC simulations also showed similar results which was governed by the temperature dependence of surface diffusion of the platinum adatoms in the thin film. Good agreement is found between experimentally observed and simulated results. A hydrogen gas sensor device was built using the platinum nanoporous thin film and it showed good response to low concentrations of hydrogen.

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.
