Nanofibrillar alginic acid‐derived hierarchical porous carbon supercapacitors
Bibliographic record
Abstract
A versatile route has been demonstrated for the preparation of hierarchical porous carbon films derived from nanofibrillar alginic acid extracted from brown seaweeds. An acetic acid‐sodium acetate buffer was used to adjust pH of the nanofibrillar alginic acid gels, giving rise to a stable aqueous homogeneous suspension at the concentration of 5.0 wt% and pH ∼4.5. A crack‐free nanofibrillar alginic acid film with a diameter of several centimeters was cast from the suspension. Self‐condensing silica around nanofibrillar alginic acid formed silica‐alginic acid composites that were carbonised and then etched the silica to generate mesoporous carbon films. The aligned mesochannel carbon was originated from the hierarchical parallel organisation of the self‐assembled nanofibrillar alginic acid. The introduction of mesoporosity into the carbon structure afforded the high‐surface‐area mesoporous carbon film‐based supercapacitor that exhibits an ultrahigh‐rate capability and highly electrical capacitance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
