Preparation of LaFeO3 Porous Hollow Nanofibers by Electrospinning
Bibliographic record
Abstract
Polyvinyl Pyrrolidone (PVP)/[La(NO3)3+Fe(NO3)3] composite nanofibers were fabricated by electrospinning. SEMmicrographs indicated that the surface of the prepared composite fibers was smooth, and the diameters of the nanofiberswas in the range of 1-3μm. XRD analysis revealed that the composite nanofibers were amorphous in structure. LaFeO3nanofibers were fabricated by calcination of the PVP/[La(NO3)3+Fe(NO3)3] composite fibers. The diameters of LaFeO3nanofibers were smaller than those of the relevant composite fibers. The surface of the LaFeO3 nanofibers becamecoarse with the increase of calcination temperatures. LaFeO3 hollow-centered and porous nanofibers formed bynanoparticles were acquired when firing temperature was 600-800ºC. SEM images indicated that the diameters of thesynthesized LaFeO3 nanofibers ranged from 500 to 800nm, and their lengths were greater than 100????m. XRD analysisrevealed that LaFeO3 nanofibers were orthorhombic in structure with space group Pn*a. Possible formation mechanismfor LaFeO3 nanofibers was preliminarily proposed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
