Defects and Deformation of Boron Nitride Nanotubes Studied by Joint Nanoscale Mechanical and Infrared Near-Field Microscopy
Bibliographic record
Abstract
Boron nitride nanotubes (BNNTs) are a one-dimensional material with high mechanical strength, good electric insulation, exceptional thermal conductivity, and high temperature stability. The presence of defects and deformations in BNNTs at the nanoscale affects their mechanical properties. In this article, we jointly utilize nanomechanical characterization and infrared scattering type near-field microscopy on the same individual BNNTs to study the defects and deformations. A characteristic structural defect of BNNT is revealed by a blue-shift of infrared absorption and discontinuity in adhesion. Polygonal facets have been observed in BNNTs, as supported by their mechanical responses and spectroscopic signatures. The presence of polygonal facets implies one should expect reactive chemical and hyperbolic optical properties of BNNTs.

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.
