Abstract

fetched live from OpenAlex

Three-dimensionally (3D) aligned, high-density, hierarchically structured single crystalline W 18 O 49 nanowires have been built on carbon microfibers of commercially available carbon paper via a chemical vapor deposition (CVD) technique without the use of a catalyst or vacuum system. The resultant W 18 O 49 nanowires radially cover carbon microfibers with controlled length and density. After a carefully controlled annealing treatment, stoichiometric WO 3 nanowires have also been achieved without losing their 3D hierarchical structure. Morphology, phase structure, and crystallinity of the nanowires have been characterized by a field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and high resolution transmission electron microscopy (HRTEM). The growth mechanism of the nanowires has been discussed. Electrochemical and corrosion behavior of the W 18 O 49 and WO 3 nanowires has been evaluated by cyclic voltammograms and an acid immersion method, respectively. These 3D hierarchical composite structures consisting of tungsten oxide nanowires grown directly on carbon microfibers may have great potential applications in fuel cells, chromogenic sensors, and other chemical nanodevices.

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.
