Electrochemical response of n-type bismuth telluride based thermoelectric materials in NaCl solutions: A comparison between a single-phase alloy and a nanocomposite containing MoS2 nano-particles
Bibliographic record
Abstract
This work presents a systematic assessment of electrochemical responses of n-type bismuth telluride-based thermoelectric materials in NaCl solutions. A single-phase alloy and a nanocomposite (with embedded MoS2 nanoparticles) produced by means of mechanical alloying and hot extrusion were investigated. The polarization and electrochemical impedance spectroscopy tests in NaCl solutions revealed that the passivity of the nanocomposite specimen was considerably improved compared with the coarse-grained single-phase alloy. Mott–Schottky analysis revealed that passive layers of both single-phase alloy and nanocomposite specimens had an n-type semiconducting behavior, and the donor density reduced in the passive layer of the nanocomposite specimen.

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.
