Line them up: Uniform CeVO4 nanorod arrays (see picture) were synthesized in a self-assembly approach assisted by ethylenediaminetetraacetic acid (EDTA) molecules in aqueous media. EDTA is important not only in controlling anisotropic growth by restricting the active points of certain faces, but also in mediating the assembly by forming intermolecular hydrogen bonds.
