Abstract
We have found that the free-radical polymerization of N -isopropylacrylamide (NIPAM) in water initiated by potassium persulfate at temperatures well above the phase transition temperature leads to the formation of gel nanospheres instead of linear chains even in the absence of added cross-linker. These particles, with radii of several hundred nanometers, resemble normal NIPAM microgels in every aspect except that they are characterized by lower solid contents and larger swelling ratios than N, N ‘-methylene bis(acrylamide) cross-linked microgels synthesized under similar conditions. Without added cross-linker, the formation of gel nanospheres is attributed to self-cross-linking by chain transfer reaction during and after polymerization.

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
