Core spherical agglomerates

An agglomerated product of spherical particles with a mean particle size on the order of 0.5 fxm was obtained when the polar core contained 0.1 M A1(N03)3. However, Matson et al. [44] did not identify the Al(OH)3 phase obtained in their experiment. Decreasing the aluminum salt concentration resulted in smaller but more highly agglomerated particles. The observed decrease in primary particle size with decrease in Al- + concentration is suggestive of the trend depicted in Fig. 6a. 

Similar to simulating the self-assembly of ceria nanoparticles into nanochains (ID assembly), the nanoparticles can also be assembled into nanosheets (2D assembly) and framework architectures (3D assembly). In particular. Fig. 5.16 shows spherical Ti-Ce02 core-shell nanoparticles assembled in three dimensions to form mesoporous architectures. Under MD simulations the nanoparticles attach and agglomerate together to form the walls of the mesoporous...
