Abstract

fetched live from OpenAlex

In order to increase the range of coronal chemistries available for crystallization-driven self-assembly protocols a series of highly asymmetric diblock copolymers comprising a crystallizable polyferrocenyldimethylsilane (PFS) block and a polymethacrylate coblock (poly(tert-butylmethacrylate) (PtBMA), poly(n-butylmethacrylate) (PnBMA), and poly(N,N-dimethylaminoethylmethacrylate) (PDMAEMA), block ratios PFS core : corona = 1 : 14–1 : 21) were synthesized by sequential living anionic polymerization. Self-assembly of these block copolymers in acetone yielded cylindrical micelles with a crystalline PFS core (confirmed by wide-angle X-ray scattering) and a polymethacrylate corona. The cylindrical micelles were fragmented by sonication and the short micelles were successfully used as “seed initiators” to grow longer monodisperse cylindrical micelles with controlled lengths from added unimers via crystallization-driven living self-assembly. Block co-micelles were also prepared by the sequential addition of unimers with a different coronal block to pre-existing cylinders.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
