Bibliographic record
Abstract
Abstract Carbanion‐based ionic liquids are proposed and utilized as the key components for the construction of five super‐nucleophilic deep eutectic solvents (SNDESs) in the paper. The super‐nucleophilic nature of carbanion‐based ionic liquids (ILs) is found to enable the capture of CO 2 with large absorption capacity. However, the absorption is very slow in the IL due to high viscosity. The synergy of carbanion siting and hydrogen bonding is found to enable high and fast absorption of CO 2 in [N 2222 ][CH(CN) 2 ]‐ethylimidazole (Eim), and a synergistic absorption mechanism is proposed and validated from spectroscopic analyses and quantum calculations. The enthalpy change of CO 2 absorption in [N 2222 ][CH(CN) 2 ]‐Eim is calculated to be −39.6 kJ mol −1 according to the thermodynamic model, and the moderate value implies that both absorption and desorption of CO 2 in the DES are favored and well balanced. The carbanion and hydrogen bond mediated by SNDESs provides a novel insight into the efficient CO 2 capture.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
