Immobilization of Multi-Carbonyl Molecules on High Surface Area Carbon for Energy Storage Applications
Bibliographic record
Abstract
The synthesis of diamino-aryl-1,4,5,8-naphtalenetetra-carboxylic diimide molecule (NTCDA-(aryl-NH2)2) was reported. This molecule was characterized by elemental analysis, SEM, IR and TGA. A organic Li-ion electrode with NTCDA-(aryl-NH2)2 as active material was tested and a reversible behavior was observed with a multiple electrons process delivering about 100 mAh.g-1 at an average potential of 2.45 V vs. Li/Li+. In parallel, the diazotization study of this molecule was investigated with a three-electrode assembly. Then, the electrochemical reduction of freshly formed NTCDA-(aryl-N2 +)2 ions was followed by cyclic voltammetry experiments. An irreversible cathodic wave at around 0.0 V vs. Ag/AgNO3 that is associated to the reduction of the in-situ generated NTCDA-(aryl-N2 +)2 ions was observed. The blocking effect of the grafted layer deposited on the glassy carbon surface was verified with ferrocene as a redox probe. Finally, the immobilization of this molecule on Ketjen black carbon powder by spontaneous reduction of freshly formed NTCDA-(aryl-N2 +)2 ions was realized in a one-pot reaction. The redox-active carbon with a loading of grafted groups estimated between 26.4 and 36.7 wt. %, depending of the method of modification, cycled at high rate for thousands of cycles.

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.
