Microscopic, structural, and electrical characterization of the carbonaceous materials synthesized from various lignin feedstocks
Bibliographic record
Abstract
ABSTRACT Microscopic, structural and electrical characterization of the carbonaceous materials synthesized from different types of lignin precursors are investigated employing scanning electron microcopy (SEM), Raman spectroscopy, X‐ray diffraction, and AC conductivity techniques. Lignin precursors from various resources carbonized at 900°C for 6 h under nitrogen atmosphere are used for this study. SEM analysis indicates formation of various microstructures, which are highly influenced by the carbonization behavior of lignin feedstocks that varies with chemical composition as well as purity. Raman spectroscopy of the carbon materials shows significant variations of its features, which represents their unique carbonization behaviors and graphitization events. Clear understanding of peak intensity, shape, and area gave very different structural features influenced by their chemical environment of the chosen precursor lignins. Phase purity and the graphitization degree are investigated through their X‐ray diffraction patterns. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41786.

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.
