Abstract

fetched live from OpenAlex

Abstract The response of potentiometric anion selective electrodes employing undoped GaN or In 0.2 Ga 0.8 N films as sensing element to detect various anions was investigated in solutions of KF, KNO 3 , KCl, HOC 6 H 4 COONa, KSCN, CH 3 COOK, KClO 4 and KBr salts. The calibration plots for the GaN and In 0.2 Ga 0.8 N semiconductor electrodes contained linear regions extending over four decades of activity change in most solutions. The structure of the GaN and In 0.2 Ga 0.8 N semiconductor electrode/ electrolyte interface was studied through electrochemical impedance spectroscopy. Analogous equivalent circuits modeling the GaN or In 0.2 Ga 0.8 N electrode/electrolyte interface were proposed and their parameters were calculated. The space charge layer of the GaN and In 0.2 Ga 0.8 N semiconductors dominated the impedance of the electrochemical system at high frequencies (>10 kHz), whereas at low frequencies (<10 kHz), the impedance was controlled by the diffusion of electroactive species across the layer of adsorbed ions at the surface of the electrode. Results imply a strong dependence of the electrodes performance on the adsorption capacity of tested anions.

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.
