Abstract

fetched live from OpenAlex

This work compares the properties of thin, porous Ir and Pt films, formed by electrodeposition (ED) from solutions containing their respective chloro-complexes, in preparation for the future co-electrodeposition of thin Pt-Ir alloy films for electrocatalytic applications. ED was carried out on Au using potentiodynamic and potentiostatic methods with simultaneous in situ mass measurements, using the quartz crystal microbalance technique. While Ir ED is found to depend on the ED potential in a more complex manner than does Pt, the specific surface area (SSA) of both metal films increases linearly with potential, but decreases with increasing solution concentration. All of the films were found to be highly porous, as confirmed using field emission scanning electron microscopy. The optimum conditions for Ir ED (0.2 V vs. RHE and a precursor concentration of < 0.05 mM) were found to be very suitable for Pt ED as well, giving films 1 to 5 nm in thickness, 25% in porosity, and exhibiting an ED charge efficiency of 75–95%.

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.
