Abstract
In a block-selective solvent for the B and D blocks of two diblock copolymers B−C and C−D, both diblocks should form micelles. Normally chains of the different diblocks do not mix significantly or comicellize for repulsion between the B and D coronal chains. This paper describes the tagging of the C blocks by adenine (A) and thymine (T), a H-bonding nucleic acid pair, to enhance mixing of the different diblock chains in a micelle. This enhancement effect has been observed in the premixed micelles prepared by first mixing the two diblocks in a solvent good for all of the three blocks and then adding a block-selective solvent for B and D. The A and T tagging has been shown also to enhance mixing of chains of different diblocks among the premade or the initially pure B−C and C−D micelles. While the A and T tagging helped give mixed micelles or micelles consisting of chains of both diblocks, the intrinsic repulsion between the B and D chains made them segregate into interesting patterns, including being two-faced and flowerlike in the coronas of the mixed premade micelles. Mixed micelles with surface-segregated chains may have intriguing applications.

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 it
