(a-d) SEM images of highly porous control Al (a) and Al+1%CNT (volume fraction) (b), and indented area observations on control Al (c) and Al+CNT composites (d)[79]
(e) schematic of shape changes on CNT, recombination, and helium out-gas[79] (f-h) molecular dynamics (MD) simulation snapshots (Ni: small red dots, C: small black spheres, He: blue spheres)[81] (f) at t=0, when Ni/C atoms are replaced at random by He (g) evolution 0.05 ns later (h) 1.0 ns later. In Figs.9g and h, He atoms are diffusing along the interior and exterior walls of the CNT, far from the CNT center. When no CNT wall defects are included He atoms diffuse only along the CNT external wall
