“…In each case, the contents of the first set of parentheses relate to the innermost nanotube; the contents of the second set of parentheses relate to the middle nanotube, and (only in the case of TWBNNTs) the contents of the last set of parentheses relate to the outermost nanotube. For example, an (11,11)@ (15,15) DWBNNT is a double-walled nanotube with an inner (11,11) nanotube and an outer (15,15) nanotube, while an (8,8)@(11,11)@ (15,15) TWBNNT is a triplewalled nanotube with an innermost (8,8) nanotube, a middle (11,11) nanotube, and an outermost (15,15) nanotube. Furthermore, it should be noted that the major diameter of a DW/TW BNNT is equal to the diameter of its outermost nanotube, and only the diameter of the inner nanotube was varied for the DW/TW BNNTs examined in the simulations performed in this work.…”
