Abstract
Abstract Summary: PBMA‐PCEMA block copolymer micelles, consisting of poly(2‐cinnamoyloxyethyl methacrylate) (PCEMA) cross‐linked core and poly(butyl methacrylate) (PBMA) hairs (shell), are used as model responsive soft colloids, where the core swelling can be tuned by changing solvent quality. Our extensive dynamic light scattering study, complemented by viscosity and small angle neutron scattering (SANS) measurements, demonstrates the richness of dynamics of such dense micellar suspensions and in particular the strong influence of solvent‐mediated core swelling on the concentration dependence of the self‐diffusion. Brownian dynamics (BD) simulations using appropriate effective core‐core interactions support these findings. Such novel micelles offer new possibilities for controlling the interactions and macroscopic properties of colloidal suspensions.

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
