Production of Carbon Nanotubes-Nickel Composites on Different Graphite Substrates
Bibliographic record
Abstract
Multi walled carbon nanotubes (MWCNTs) were synthesized on dif- ferent graphite types covered with thin layer of nickel catalyst by catalytic chem- ical vapour deposition using acetylene as hydrocarbon source. The produced car- bon nanotubes were investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The shape, quantity and diameter of the MWCNTs are shown to be affected by the type of the graphite substrate, the growth temperature and the hydrocarbon source flow rate. The diameters of the produced MWCNTs were ranged between 43 and 80 nm for pyrolytic (PYROID) and polycrystalline (AXF-5Q) graphite, respectively when the growth temperature was 800 °C and acetylene flow rate 570 cm 3 /min. This graphite containing MWCNTs can be used as a cathode in the Physical vapour de- position (PVD) system to produce MWCNTs embedded in a Diamond-like Carbon (DLC) coating.

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.
