Electrospinning Fabrication of Polycrystalline LaCrO3 Porous Hollow Nanofibers
Bibliographic record
Abstract
Polyvinyl Pyrrolidone(PVP)/[La(NO3)3+Cr(NO3)3] composite nanofibers were fabricated by electrospinning. SEMmicrographs indicated that the surface of the prepared composite fibers was smooth, and the diameter of thenanofibers was in the range of 1-3?m. XRD analysis revealed that the composite nanofibers were amorphous instructure. LaCrO3 nanofibers were fabricated by calcination of the PVP/[La(NO3)3+Cr(NO3)3] composite fibers. Thediameters of LaCrO3 nanofibers were smaller than those of the relevant composite fibers. The surface of the LaCrO3nanofibers became coarse with the increase of calcination temperatures. LaCrO3 hollow-centered and porousnanofibers formed by nanoparticles were acquired when firing temperature was 600-900ºC. SEM images indicatedthat the diameters of the synthesized LaCrO3 nanofibers ranged from 500 to 800nm, and their lengths were greaterthan 100?m. XRD analysis revealed that LaCrO3 nanofibers were orthorhombic in structure with space group Pbnm.Possible formation mechanism for LaCrO3 nanofibers was preliminarily proposed.

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.
