Improving the Performance of All-Solid-Stated Planar pH Sensor With Heat Treated Process
Bibliographic record
Abstract
All-solid-stated pH sensors based on metal/ metal oxide were widely used in mixed heterogeneous environment, such as soil or soilless cultivation. In this study, an all-solid-stated pH sensor prepared by magnetron sputtering was presented, of which the working electrode was antimony, and reference electrode was Ag/AgCl electrode, and heat treated process was conducted to improving the performance of all-solid-stated planar pH sensor. The electrodes heat treated at the temperature of 100°C, 200°C, 300°C, and 400°C were tested through surface morphology analysis, energy spectrum analysis and electrochemical experiments. The results showed that the heat-treated temperature had a remarkable effect on the performance of the pH sensor. Specifically, the pH sensor heat-treated at 200°C had excellent performance, with the sensitivity 74.0 mV/pH, the response time less than 3 s, the standard deviation less than 2 mV in 700 s period. The developed sensor can be applied in pH detection in soilless culture and is promising to popularize in industrial production.

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.
