Two-Way CO<sub>2</sub>-Switchable Triblock Copolymer Hydrogels
Bibliographic record
Abstract
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.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
