RPBB PA particle. a) plane projection of a disordered compact RPB cluster of 8192 B-grains (grey); b) cut of the RPBB PA cluster made from the B-cluster randomly coated with 2048 A-grains (red). The white circle marks the cluster effective radius (here comparable to the overall cluster radius). For comparison, cut of the coated sphere made of f c = 80% B (grey core) coated with 20% A (red mantle), is shown at a smaller scale in the bottom left of the figure. Color online.
