Ni‐Assisted Endotaxial Growth of Au Nanoparticles Within TiO<sub>2</sub> Nanowires
Bibliographic record
Abstract
Abstract 1D hybrid nanosystems, which consist of chains of nanoparticles embedded in nanowires, exhibit distinctive physical and chemical properties. However, fabricating them through vapor‐phase growth has been challenging due to a lack of understanding of their growth mechanisms. In this study, the endotaxial growth of Au nanoparticles within rutile TiO2 nanowires is demonstrated when small amounts of Ni are incorporated into the Au seed during vapor‐phase growth. The presence of Ni likely modifies the Au‐TiO2 interfaces, as evidenced by the distinctive morphologies and preferential crystallographic orientation relationships (OR) between the embedded Au nanoparticles and TiO2 nanowires. Unlike the irregularly shaped Au nanoparticles with previously reported ORs in bead‐like TiO2 nanowires grown along , Au nanoparticles have a new OR and well‐defined shape, bounded by low‐index planes from both lattices, in prismatic nanowires along . The results underscore the significance of crystallographic factors in the vapor‐phase growth of 1D hybrid nanosystems.

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.
