Interfacial Staining of a Phase-Separated Block Copolymer with Ruthenium Tetroxide
Bibliographic record
Abstract
We report on an unusual staining phenomenon of a diblock copolymer, poly(ferrocenylsilanes)- b -poly(dimethylsiloxanes) (PFS- b -PDMS). By a combination of transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) analysis, it is found that when a thin section of diblock copolymer is exposed to ruthenium tetroxide vapor, the interfaces between the PFS and the PDMS microdomains are selectively stained. The effect appears to arise from a delicate competition between reactivity and diffusion. This observation broadens our knowledge of the staining behavior of diblock copolymers and provides a potential route to pattern ordered nanoring arrays using diblock copolymers as a template.

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.
