Figure 4

TEM images of the nanospheres in contact with CNTs in the irradiated area. (a) Nanospheres of larger diameter with (1) and without (2) shells found at the tip of the thinned CNTs, and (3) nanospheres of smaller diameter beading CNTs. (b) Enlarged view of the nanosphere encapsulated into the shell (1) containing some inclusions (2) and CNTs (3). (c) The nanospheres without shells.
