Functionalized polymeric membrane with aquaporin using click chemistry for water purification application
Bibliographic record
Abstract
ABSTRACT A new type of aquaporin‐based biomimetic water purification membrane is fabricated using a propargyl functionalized β‐sheet peptide (FBP1). FBP1 is demonstrated to bind to aquaporin and form a stable protein–peptide complex in aqueous solution, as well as covalently conjugate with azide group. Substrate starting material, polysulfone (PSU), is modified with ∼1.05 azide group per repeating unit and casted into a thin film substrate with appropriate pore size structure using non‐solvent induced phase separation technique. Protein–peptide complex then is clicked onto the substrate using an in‐house built circulating system. The successful immobilization is verified by surface chemical composition analysis and surface morphology analysis. The preliminary salt rejection results show salt rejection improvement from 5% of control membrane to 12.5%. We thus demonstrate a promising method to conjugate a thin layer of membrane protein onto polymeric substrate and well maintain the functionality of membrane proteins. © 2018 Wiley Periodicals, Inc.

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.
