Homogeneous Crystal Nucleation Near a Metastable Fluid-Fluid Phase Transition Xu, Limei Buldyrev, V. S. (Vladimir Sergeevich) Stanley, H. Eugene (Harry Eugene), 1941- Franzese, Giancarlo Física de partícules Experiments Particle physics Experiments Several scenarios exist for the protein crystallization and aggregation in solutions near a metastable fluid-fluid phase separation below the solubility line. Based on computations, it was proposed that the fluid-fluid critical point enhances the crystallization rate by many orders of magnitude, while, based on experiments, it was proposed that the fluid-fluid spinodal controls the crystallization rate. Using molecular dynamic simulations for an isotropic model with sticky interaction, we show that neither of these scenarios adequately describes the crystallization mechanism near a metastable fluid-fluid phase separation. We find that the emergence of the high-density fluid inside the spinodal drastically enhances the crystal nucleation in the subcritical region following Ostwald's rule of stages. 2019-05-22T14:34:43Z 2019-05-22T14:34:43Z 2012-08-27 2019-05-22T14:34:43Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.109.095702 Physical Review Letters, 2012, vol. 109, num. 9, p. 095702 https://doi.org/10.1103/PhysRevLett.109.095702 info:eu-repo/grantAgreement/EC/FP7/266737/EU//NANOTRANSKINETICS (c) American Physical Society, 2012 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
