Cyclic Voltammetric Study of a Polarized Electrochemical Vapor Deposition Process
Bibliographic record
Abstract
The recently developed polarized electrochemical vapor deposition (PEVD) is a process which actively uses mass and charge transport within Wagner's electrochemical tarnishing theory for product formation. Since the migration of charged ionic and electronic carriers during PEVD is a kinetic process, it is imperative to solve the PEVD reaction rate‐limiting steps for samples undergoing both stage I and II growth. The PEVD process for Na 2 CO 3 auxiliary phase deposition at the working electrode of a potentiometric CO 2 sensor was selected for the current solid electrolyte cyclic voltammetry studies. The results from this investigation not only confirm the previous steady‐state potentiostatic studies for samples undergoing stage II growth, but also reveal qualitatively the kinetics of the PEVD reaction and subsequent product formation in a PEVD system during stage I growth. At lower temperatures and working electrode overpotentials, the PEVD reaction rate‐limiting step is the charge transfer reaction. At higher temperatures and lower working electrode overpotentials, the rate‐limiting step is the diffusion of Na + across the product. At higher working electrode overpotentials for all temperatures, the rate‐limiting step is the surface diffusion of neutral reactants. © 2000 The Electrochemical Society. All rights reserved.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
