Additive controlled crystallization

Additives play a decisive role in crystallization processes. We survey the ongoing efforts in the realm of additive-controlled crystallization. Emphasis is placed on the commonly used and most studied types of additives and their influences on prenucleation, stabilization of amorphous precursors, nucleation, crystallization, chiral resolution, nanocrystal assembly, polymorph, and thus morphologies. We will highlight three types of nonclassical trajectories adopted by additive controlled crystallization, including oriented attachment, mesocrystals, and biomorphs.
