Abstract

fetched live from OpenAlex

Biomorphic CaCO 3 with different hierarchically ordered micro- and nanostructures was fabricated with natural cellulose substances as the host templates. The fabrication involves two mild sonication processes in which calcium and carbonate ions are sequentially added to the template, together with subsequent calcination in air. The specific pseudo-1D and pseudo-2D structures of the resultant crystalline calcite can be tailored by mimicking both natural and artificially woven cellulosic substances, with the former following the ribbon/tube form of cellulose fiber and the latter following the netlike architectures of the woven cotton cloth. The building block of these structures is a layer of CaCO 3 grains grown on the surfaces of each cellulose fiber. By choosing Ca 2+, CO 3 2-, or HCO 3 - ions as the first adsorption species on the cellulose template, we show that the resultant CaCO 3 grain size can be fine-tuned in a nanoscopic scale, most probably due to the differences in the nature of ion adsorption on the cellulose molecules and the resultant CaCO 3 nucleation and growth. The impact of this new route is that we can precisely predict the morphologies of the final CaCO 3 products that were not realized in other chemical approaches.

Full frame distilled prediction

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.
