Figure 4
A series of 3D semi-transparent renderings of the polymer core. The same microsphere was exposed to the X-ray beam for (a) 480 s, (b) 1440 s, (c) 2880 s, (d) 4800 s and (e) 6720 s. (Corresponding doses: 2.2, 6.5, 13, 22, 30 GGy.) The painted semi-transparent silver color illustrates the metal coating, the green color represents the polymer core and the aqua color represents polymer of reduced density. After almost two hours of integrated exposure, the bubble fills 97% of the volume inside the metal coating, as seen in (e). (f) An xy-cross section of the first tomogram (t = 480 s) showing a hole in the coating, indicated by the blue arrow. The hole in the coating appears to be the initiation point of the bubble. The color bar gives the electron number density per cubic Ångström.
