Abstract
A method of crystallization is provided. The method includes providing a solution comprising a solute dissolved in a first solvent. The method includes providing a dispersion comprising a plurality of nanoparticles in a second solvent. The first solvent and the second solvent are mutually miscible. The method includes combining the solution and the dispersion to form a mixture. The nanoparticles remain dispersed in the mixture and the solute remains dissolved in the mixture at or below a saturation concentration. The method includes cooling the mixture such that the solute exceeds the saturation concentration forming crystals in the presence of the dispersed nanoparticles. The method includes separating the crystals from the mixture, wherein the nanoparticles remain dispersed in the mixture.
