Surface Free Energy of Cubic Boron Nitride Films Deposited on Nanodiamond
Bibliographic record
Abstract
Thin and thick cubic boron nitride (cBN) films were grown on nanodiamond (nanoD), using radio-frequency magnetron sputtering and plasma-enhanced chemical vapor deposition. The chemical composition of the cBN surface layer was nearly stoichiometric, which yielded an essentially pure cubic phase. The root-mean-square roughness of the nanoD and cBN films varied from 4 to 37.5 nm, depending on the pretreatment, method of deposition, and film thickness. The surface free energy of the cBN films with respect to the nanoD was determined by the contact angle measurements. The surface free energy was affected by surface roughness, but the surface energy of nanodiamond was always slightly higher than that of cBN films. This relationship between the surface free energies has important implications for material compatibility and possible local heteroepitaxial growth of cBN on nanoD.

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.
