MROs in the glass-forming nanoparticle (Adapted from ref. [60]. Copyright©2021, Springer Nature). (A) Representative pairs of solute-center clusters connected with each other by sharing one to five atoms. (B) 3D atomic packing of four crystal-like stacking MROs. Large red spheres are the solute centers in fcc- (top left), hcp- (top right), bcc- (bottom left) and sc-like (bottom right) MROs. The solvent atoms have been removed and the solute centers are orientated along the fcc, hcp, bcc and sc zone axes to better visualize the crystal-like MROs. (C) Distribution of the four types of MRO with eight solute-center atoms or more.
