Abstract
This study demonstrates the continuous conversion of CO 2 to CH 4 in a laboratory-scale Microbial Electrosynthesis System (MES). The introduction of a Ni salt at 0.2 g L -1 into the cathode influent stream improved the CO 2 conversion. After the introduction of the Ni salt at an applied voltage of 2.8 V, the MES with the carbon-felt cathode reached a CH 4 production of 422 ± 36 mL d -1 (0.81 L L c -1 d -1 ), which was 39 ± 12% higher than that of this system before the Ni salt was introduced. Additionally, when the dissolved Ni salt was removed from the influent solution, the MES performance remained unchanged, thus confirming the in-situ deposition of Ni on the carbon-felt cathode and its catalytic effect.

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 it
