Abstract
Polyamide is the most commonly used selective layer in nanofiltration membranes at an industrial scale. However, polyamide membranes lack flexibility, as their performance in terms of rejection and flux becomes fixed once the membrane is formed. Although several studies have explored during- and post-fabrication modifications of polyamide membranes, these approaches result in irreversible changes to membrane properties. Herein, we developed an electrically conductive polyamide membrane with dynamically tunable salt rejection performance by applying external positive or negative potentials. The observed changes in membrane performance were reversible, indicating that the chemical and structural integrity of the membrane is maintained. Furthermore, unlike findings from previous studies, the salt rejection performance of this membrane remains uncompromised even at voltages that induce electrochemical reactions. These results highlight the potential of this membrane for adaptive filtration systems and applications requiring electrochemical reactions without sacrificing separation efficiency.

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
