Abstract

fetched live from OpenAlex

Three independent polymer/polymer complexing mechanisms were used to assemble polymer trilayers onto anionic surfaces in water. Polymer-surface and polymer-polymer attraction were driven by (1) electrostatic attraction between positive polymers bearing benzyl trimethyl ammonium chloride (BTM) groups and negative surfaces; (2) polyethylene glycol (PEG) binding to phenolic (Ph) groups; and (3) phenylboronate (PBA) binding to polyols. The approach was to prepare copolymers with the following pairs of compatible interacting groups: BTM/Ph, BTM/PEG, PBA/PEG, and PBA/Ph. The supporting surfaces were either silicon or anionic self-assembled on gold. The ultimate goal is to employ independent polymer/polymer interactions to prepare complex assemblies in a few steps.

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.
