Ball Milling to Build the Hybrid Mesocrystals of Ibuprofen and Aragonite

Figure 2

SEM images of IBU/aragonite after ball milling for (a) 120 and (b) 240 min; IBU/calcite after ball milling for (c) 120 and (d) 240 min. Arrowheads of (a) and (b) indicated the aragonite needles, and those of (c) and (d) indicated IBU. Also shown in the insets of (a) and (b) were the submicron domains as well as the needles of aragonite integrated with IBU.
