Abstract

fetched live from OpenAlex

) (Fp-pyrene) is soluble in DMSO and THF, but insoluble in water, methanol, and ethanol. The hydrophobic force drives the molecules' assembly into vesicles in THF/water. The π-π interaction of the pyrene groups subsequently occurred within the vesicular membrane. The assembly, however, is driven by the π-π interaction in DMSO/water (water content: 40-80 vol %) into membranes, which is attributed to the relatively higher degree of de-solvation (δ) of pyrene in DMSO. Further increase in δ (DMSO/90 vol % water) suppresses the π-π interaction and spherical particles are formed. On the other hand, the supersaturated solutions were prepared via a cycle of heating and cooling of Fp-pyrene in methanol or ethanol. Fp-pyrene aggregates into particles without the π-π interaction in the solutions with a lower degree of supersaturation (σ). In contrast, a higher σ induces the π-π interaction, which drives the assembly into nanotapes. The π-π interaction is a conditional effect depending on the solution conditions, which can be adjusted for the synthesis of nanostructures assembled from the same aromatic molecule.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
