Practically, computational challenges mean this approach has yet to find applications to study crystal nucleation. This is because the spontaneous decomposition of a highly supersaturated solution is unlikely to lead to crystals due to the slow decay times for monomer relaxation to a lattice structure in a dense amorphous precipitate. Even if sampling this monomer ordering were feasible over MD timescales, many more crystal geometries could result from a rapid crystallisation step, making precise estimates of 𝜎 difficult. Based on the local density, alternative formulations of CNT have also been constructed, and the finite size effects can be included here to account for the changing thermodynamic driving force.
