Abstract
Gold nanotriangles, one of a family of nanoprisms, have attracted a great deal of interest due to their promising applications in catalysis, electronics, imaging, diagnostics, and photothermal therapy. The crucial role of iodide in the formation of anisotropic gold nanotriangle (AuNT) has been assigned to the inhibition of Au(111) facet growth and as a digestion agent (as I 3 – ) of non-nanotriangle impurities. However, neither I – nor I 3– are detectable in the reaction conditions of the growth solution. Instead, an Au(I) complex, [AuI y Cl 2– y ] -, has been identified for the first time as a synthetic precursor of Au nanotriangles. This complex forms in solution on mixing AuCl 4 –, I –, and ascorbic acid. [AuI y Cl 2– y ] is readily reduced by ascorbic acid to form in situ AuNP seeds. Preferential adsorption of in situ generated I – on the Au(111) facets of the Au(0)NP seeds, relative to the Au(100) edges of a developing plate, results in the selective growth of the latter compared to the former. Control of the formation and reaction conditions of this precursor complex provides an entry point to the sought-after reproducible, one-pot synthesis of AuNT. This refinement of the role of iodide introduces approaches to control the outcomes of the metal nanoparticle synthesis.

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.
