Well‐rounded : Water‐dispersed colloidal spheres that are self‐assembled from nanocrystals with different size, shape, composition, and surface ligand were prepared through a versatile emulsion‐based self‐assembly (EBS) approach. Through this emulsification process, a dispersion of BaCrO 4 nanocrystals in cyclohexane (see picture, left) can be transformed into a dispersion of colloidal spheres of BaCrO 4 (see picture, right).
