WebApr 14, 2024 · Sundareswaran et al. [ 13] found that solute concentration-mediated supersaturation can trigger crystal nucleation and polymorphism by varied solute concentration. Sometimes nucleation and metastable region coexist. Lower supersaturation is more helpful for I and moderate supersaturation more conducive to II Nucleation. WebSolution crystallization is the transformation of a substance from liquid state to crystalline state and its process undergoes two steps, which are nucleation and crystal growth. Nucleation is the generation of a number of crystal nuclei in the supersaturated solution and crystal growth is the further growth of crystal nuclei. low income and alcohol abuse
