Controlled Incorporation of Particles into the Central Portion of Block Copolymer Rods and Micelles
Bibliographic record
Abstract
The controlled incorporation of preformed gold nanoparticles (AuNPs) into only the central portion of polystyrene 190 - block -poly(acrylic acid) 20 (PS 190 - b -PAA 20 ) block copolymer rods and micelles is described in this note. The strategy involves the formation of the rods or micelles in solution in the presence of AuNPs coated with PS 270 - b -PAA 15 diblock copolymer. Statistical analysis shows that about 80% of the AuNPs are incorporated into the central ca. 4 vol % portion of the rods. The method does not require the block copolymers to bind, solvate, or otherwise interact during preparation with the ions of the metal involved, nor does it involve postassembly chemical reactions within the aggregates, and is thus suitable for a wide range of particles and block copolymer systems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
