The structural, energetic and electronic properties of chiral ( n, m) (3⩽ n⩽6, n/2⩽ m⩽ n) single-wall copper nanotubes (CuNTs) have been investigated by using projector-augmented wave method based on density-functional theory. The (4, 3) CuNT is energetically stable and should be observed experimentally in both free-standing and tip-suspended conditions, whereas the (5, 5) and (6, 4) CuNTs should be observed in free-standing and tip-suspended conditions
Where do you guys come up with this...![]()
There is no excuse for the Secret Service to have NOT seen this asshole before he had a chance to start shooting into a crowd of people - LOOK AT THE SIZE OF HIS FUCKING FIVE HEAD - that thing is big enough to mount a solar panel on it.
