Impact of Li/Na/K Nitrate Electrolytes on Commercial Photoelectrochemical Oxygen Demand Devices
Bibliographic record
Abstract
This study investigates the influence of nitrate-based electrolytes─specifically LiNO 3, NaNO 3, and KNO 3 ─on the performance, reproducibility, and operational efficiency of Photoelectrochemical Oxygen Demand (PeCOD) devices. A systematic evaluation was conducted across three operational concentration ranges to identify the interplay between ionic conductivity, charge transport dynamics, and reaction kinetics. The findings reveal that each electrolyte exhibits distinct advantages depending on the concentration regime, with KNO 3 offering superior conductivity and sensitivity in the high-concentration regimes, while preserving equivalent stability and reproducibility under lower concentration conditions than the alternatives. Modeling and analysis of the reaction rates highlight intrinsic electrolyte-specific variations which play a role in the overall sensitivity and selectivity of the system. These insights have significant implications for optimizing PeCOD devices in commercial and environmental applications, paving the way for further innovations in water quality monitoring and related fields.

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.
