Abstract

fetched live from OpenAlex

CO 2 -responsive ABA triblock copolymer hydrogels are described. Through rational block copolymer design, these hydrogels could undergo either CO 2 -induced gel-to-sol or the reverse sol-to-gel transition. While the middle block B is water-soluble, the solubility of the two end blocks A can be switched by CO 2 . For the gel-to-sol transition, the A block was made to have a lower critical solution temperature (LCST) that can increase upon CO 2 bubbling, while for the sol-to-gel transition, the A block was designed to have a LCST that decreases with CO 2 . Repeated cycles of hydrogel formation and dissociation could be achieved by simply passing CO 2 and an inert gas alternately through the solution, at a constant temperature and without adding acids and bases for pH change. Moreover, CO 2 -induced release of an encapsulated protein was demonstrated.

Full frame distilled prediction

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.
