The measured E Radial of MW BN-NTs investigated in this work (black solid square). The vertical (black) and horizontal (green) error bars of E Radial are calculated from averaging multiple MoNI measurements and the uncertainty of the layers in BN-NTs, respectively. We use light green color for horizontal error bar for R NT > 9 nm to increase figure clarity. The E Radial of MW C-NTs (red solid circle) from Ref. 15 is shown for comparison. The solid lines are the best fit to these data with the equation: E Radial = A/(R ext 2(R int − 0.34 nm)2) + E o. The dotted line is the best fit of the equation: E Radial = A√t/(R ext 2(R int − 0.34)2) + E o, with the consideration of wall thickness, t, to the BN-NT data, where A and E 0 are constants.
