Employing Forward flux Sampling (see Section 4.2), Jiang et al. have investigated the nucleation of NaCl from brine at supersaturation ratios (𝑆 = 𝑏∕𝑏 𝑠𝑎𝑡 ) ranging between 2.1 and 4.5 . FFS allows evaluation of both the nucleation mechanism and nucleation kinetics at these conditions. Concerning the former, the authors observe that nuclei tend to assemble directly into an FCC-like rocksalt structure, independently of their size, and that the level of crystallinity of the nuclei has a strong influence on their lifetime and probability of growing. This suggests that the nucleation process at moderate supersaturations follows a mechanism that can be described by CNT. The nucleation kinetics obtained by FFS tend to underestimate experimental measurements, possibly due to an overestimation of the crystal/solution interfacial tension . Nevertheless, this dataset provides an important benchmark for studying nucleation from solution as rates here are computed independently from any theoretical interpretation of the self-assembly process.
