Abstract
The Au–TiO2 interface plays a critical role in heterogeneous catalysis and nanostructure synthesis relevant to renewable energy applications. Using Au-seeded TiO2 nanowires as the model system, we observe that, in addition to the commonly reported orientation relationships (ORs) and atomically sharp interfaces, Au–TiO2 interfaces can also exhibit ORs involving high-indexed planes, often accompanied by local disorder and atomic reconstructions involving multiple Ti-O monolayers. These interfacial rearrangements are promoted by high-temperature thermal treatment at 1000 °C during nanowire growth. The findings broaden our understanding of orientation relationships and interface structures in the Au–TiO2 system, offering valuable insights into interface-driven synthesis of oxide nanostructures and guiding future strategies for interface engineering in catalytic and electronic applications.

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
