Abstract

fetched live from OpenAlex

Woody waste materials were used for the preparation of titanium carbide ceramics (TiC) by utilizing combustion synthesis or self-propagating high temperature synthesis (SHS). The outer and inner barks and wood of the sugi (Cryptomeria japonica) were used to react with titanium powder as raw materials, as well as commercially available reagents of cellulose and lignin. It was detected by X-ray diffractometry that the TiC phase was obtained directly arose from the mixture of the woody waste materials and titanium powder, without formation of any major oxide phase. Broadening of half width and shift in diffraction peaks of the obtained TiC phase suggest that the TiC phase included lattice deformation and had a non-stoichiometric composition. This latter observation may imply the release of carbon, i.e., formation of carbon mono- or dioxide. The carbide phase had a mean particle size of 1-5μm, and showed a shape similar to a TiC synthesized from a mixture of graphite and titanium powders. The combustion velocity of the mixtures tended to increase with the relative amount of carbon included in the woody materials. On the other hand, the velocity indicated a tendency to decrease with hydrogen and oxygen contents in the materials, which resulted from an endothermic reaction, accompanied with pyrolysis of the woody waste materials during SHS reaction.

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.
