Abstract

fetched live from OpenAlex

Birnessite form of manganese dioxide has been investigated as possible electrode material for electrochemical supercapacitor applications. It has been shown that this material exhibits partial sodium cations/protons intercalation which provides pseudo-capacitance leading to a stable value of 145 F/g on 1100 cycles. The use of Mg-doped Na-birnessite as positive electrode of a hybrid carbon/MnO2 electrochemical supercapacitor has also shown an interesting capacitance of 0.12 F, stable on 17000 cycles.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
