Abstract
It has been demonstrated that dopamine can undergo oxidation and complicated self‐reaction in aqueous solution to form so‐called polydopamine (PDA). In this paper, for the first time, the hierarchical self‐assembly of dopamine into surface patterned structures is described. PDA nanoaggregates are first prepared assisted by ethylenediamine, based on the covalent self‐polymerization and noncovalent self‐assembly. The surface fractal patterns are further created and modulated by the dynamic self‐assembly of PDA nanoaggregates to develop more macroscopic ordered structure of PDA. Various surface patterns of PDA aggregates are successfully obtained by evaporative dewetting method. The effects of solution pH, type of inorganic salts, and temperature on the morphology of surface pattern are investigated. Mineralization or metal deposition is used to keep the pattern fixed. The surface patterning strategy reported here is applicable to a broad range of materials, which allows the developments of materials with controllable patterned structure.

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 it
