Anomalous Oxidation Resistance of “Core-Only” Copper Nanoparticles Electrochemically Grown on Gold Nanoislands Prefunctionalized by 1,4-phenylene Diisocyanide
Bibliographic record
Abstract
Copper was electrodeposited on bare and pre-functionalized Au nanoislands with 1,4-phenylene diisocyanide (PDI, − C≡N + –C 6 H 4 –N + ≡C − ), on a Si(100) substrate. The electrodeposited Cu nanoparticles on bare Au nanoislands are found to consist of a Cu core and a Cu 2 O shell with a CuO overlayer. For Cu nanoparticles electrodeposited on Au nanoislands pre-functionalized with PDI, the metallic Cu core is covered by a barely detectable Cu 2 O overlayer, without any evidence of the CuO shell. PDI-functionalization of the Au nanoislands could be used to suppress the Cu oxidation and significantly alter the interfacial electronic nature of Cu on PDI-functionalized Au nanoislands.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
