Abstract
Despite the diversity of nanostructures that have been created from block copolymers over the past two decades, the challenging fabrication of polymer nanocapsules bearing regularly sized nanochannels has not been possible until now. In this study, a pseudo miktoarm copolymer μ-(PtBA)(PCEMA)(PEO) 1.14 was prepared. The copolymer consisted of 1 poly( tert -butyl acrylate) (PtBA) chain, 1 poly(2-cinnamoyloxyethyl methacrylate) (PCEMA) chain, and an average 1.14 poly(ethylene oxide) (PEO) chains. This polymer formed vesicles in a tetrahydrofuran/water solvent mixture with the soluble PEO block as the corona. At 100 units long, the PtBA chains formed cylinders that permeated the wall made of PCEMA chains at 130 units long. Photo-cross-linking the PCEMA wall and hydrolyzing the PtBA chains in the cylindrical domains yielded unprecedented capsules bearing regularly packed uniform poly(acrylic acid)-gated nanochannels. These capsules exhibited pH-responsive reagent release in aqueous media.

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
