Jiang et al. , and by recent experimental and simulation observations suggesting significant ion-ion correlations occurring in supersaturated NaCl; we have recently investigated the emergent nucleation mechanism for NaCl(s) in supersaturated solutions below the limit of solution stability. To this aim, we performed multiple metadynamics simulations where we enhanced fluctuations in the local ion density to explore the configuration space of the nuclei forming in an aqueous solution. By mapping the nuclei configurations as a function of two order parameters indicative of the size of a dense cluster and of the size of a dense cluster with a crystalline structure, we collected configurations able to describe the emergence of crystalline NaCl nuclei without prescribing a specific pathway .
