Abstract
The formation of twisted cylinders with segregated A and C coronal chains from an ABC triblock copolymer in a block-selective solvent for the A and C blocks is reported. Such cylinders consisted of left- and right-handed helical sections (3D twisting) connected by wriggling (2D twisting) sections after aspiration on a solid substrate. The copolymer used was poly(glyceryl monomethacrylate)- block -poly(2-cinnamoyloxyethyl methacrylate)- block -poly( tert -butyl acrylate) or PGMA- b -PCEMA- b -PtBA consisting of 310 PGMA units, 130 CEMA units, and 110 tBA units. Twisted cylinders were prepared from the dialysis of an aqueous solution of the triblock copolymer against methanol. In water, the copolymer formed core−shell−corona cylinders with the insoluble PtBA and PCEMA blocks making up the core and shell and the soluble PGMA block making up the corona. The cylinders with PCEMA cores twisted in water/methanol with high methanol contents, e.g., >90 vol%, probably to create more space to accommodate the segregated PGMA chains, which were longer, better solvated, and more crowded than the PtBA chains. Also investigated is the mechanism for the morphological transition from the core−shell−corona cylinders in water to the twisted cylinders in water/methanol.

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 it
