Abstract

fetched live from OpenAlex

Diblock copolymers composed of a side-chain liquid crystalline azobenzene-containing polymethacrylate and poly( tert -butyl acrylate) (PAzoMA- b -P t BA) were prepared using atom-transfer radical polymerization (ATRP). After subsequent selective hydrolysis of P t BA yielding poly(acrylic acid) (PAA), amphiphilic diblock copolymers of PAzoMA- b -PAA were obtained. Aggregation of either PAzoMA or PAA block occurs in solvents selective for one of the blocks. Adding water into dioxane solution of PAzoMA- b -PAA forms micellar aggregates due to the hydrophobic PAzoMA block. Under alternating UV and visible light illumination, reversible changes in micellar aggregates, for both core−shell micelles and vesicles, took place as a result of the reversible trans−cis photoisomerization of azobenzene mesogens in PAzoMA.

Teacher imitation

Not 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.
