Carbon nanotubes (CNTs), an allotrope of carbon, show modifications in properties when impurities like boron, nitrogen, and lithium are deliberately introduced in their matrix [1 3].
Based on TEM images, the diameter of the pure and boron-incorporated CNTs samples are found to be in the range of 40 60, and 10 40 nm, respectively.

Figure 5 shows the (002) Bragg's peak corresponding to graphite of pure as well as boron-incorporated CNT samples using the grazing incidence X-ray diffractometry (GAXRD).

Considering this fact, we can clearly explain the structural modifications in samples B5NT, B10NT, and B15NT as being due to the incorporation of boron.
Few modifications are incorporated in proposed heuristic for the application of PCA and Taguchi's method.
No modifications in α-helix were found upon the toxin's binding with liposome-incorporated cholesterol.
We speculate that these structural modifications in the morphology and microstructure of CNTs might be due to the charge transfer from boron to the graphite matrix, resulting in shortening of the carbon carbon bonds.
