Pressure‐Induced Ultralow Critical Micelle Concentration of Surfactant for Encapsulating Dye
Bibliographic record
Abstract
Achieving the ultralow critical micelle concentration (CMC) of the surfactant encapsulating the dye has spawned a vital pathway to boost the efficiency and stability of dye-sensitized solar cells (DSSCs). The attainment of ultralow CMC while sustaining the constant micelle presents a significant challenge. Here, by an ingenious pressurizing strategy, the ultralow CMC is obtained for the immobilized micelle. The ultralow CMC of cetyl trimethyl ammonium bromide (CTAB) is performed under pressure by the detection of encapsulated coumarin 35 (C35) attractively. At 0.80 GPa, the CMC of CTAB is decreased ≈111-fold to 8.3 ± 0.1 µm compared to 917.2 ± 8.7 µm at 0.10 MPa. The ultralow CMC under pressure is probed relying on the quenched fluorescence background of C35. Femtosecond transient absorption spectra confer a clear picture that the pressure-induced fluorescence quenching is ascribed to the reinforced competition for the twisted intramolecular charge transfer process of the C35. This study provides a robust strategy for achieving ultralow CMC, laying the groundwork for the efficient application of DSSCs.

How this classification was reachedexpand
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.
