Hydrogen Bonded Assembly of Poly(acrylic acid)-<i>block</i>-poly(<scp>l</scp>-valine) in Dilute Solutions
Bibliographic record
Abstract
The self-assembly of four hybrid poly(acrylic acid)- block -poly( l -valine) (PAA- b -PLVAL) block copolymers (i.e., PAA 40 −PLVAL 100, PAA 80 −PLVAL 100, PAA 80 −PLVAL 80, and PAA 80 −PLVAL 60 ) was investigated. Formation of core−shell spherical micelles was observed, and it correlated with the extent of β-sheet ordering in PLVAL hydrophobic domains. PAA 80 −PLVAL 60, having the lowest β-sheet content (12%), existed only as random aggregates at pH < 5 and in an unaggregated state at high pH. The β-sheet formation also produced an unusual pH dependence of the micelles, where the swelling of micelles occurred only within a narrow degree of deprotonation (α) range of between 0.15 to 0.2 and 0.4 to 0.5 for PAA 80 −PLVAL 80 and PAA 80 −PLVAL 100, respectively. An additional role of the length of the PAA segment was identified as providing sufficient shielding to the hydrophobic core, which prevents further association into large compound micelles, as was observed for PAA 40 −PLVAL 100 .

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
