Abstract

fetched live from OpenAlex

Zirconium oxide (ZrO 2 ) thin film was deposited on nitrogen-doped carbon nanotubes (NCNTs) by atomic layer deposition (ALD) using tetrakis(dimethylamido)zirconium(IV) and water as precursors. The observation using scanning electron microscope and transmission electron microscope (TEM) revealed that the tubular films of 100-cycle ZrO 2 were very uniform and conformal on NCNTs. Further characterization using X-ray diffraction, Raman spectroscopy, selected area electron diffraction, and high-resolution TEM disclosed that the crystallinity of the deposited ZrO 2 films was controllable with deposition temperatures in the range of 100–250 °C. In contrast to the pure amorphous ZrO 2 film deposited at 100 °C, tetragonal crystalline ZrO 2 film was prepared at 250 °C, while a mixture of the former two phases was found between 150 and 200 °C. In all cases, the growth of ZrO 2 tubular films on NCNTs showed a transformation from an island-growth mode to a layer-by-layer growth mode with increasing ALD cycles. The ZrO 2 –NCNT nanocomposites with controllable crystallinity will have great potential for various applications in fuel cells, batteries, electronics devices, and chemical sensors.

Teacher imitation

Not 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.
