Continuous dialysis allows us to discover and spatially resolve crystal structures with similar nucleation energy barriers, which might be overlooked in experiments using static interaction potentials. For example, in sealed capillaries, binary mixtures with β = 0.81 primarily form CsCl-like crystals that take on macroscopic rhombic dodecahedral shapes (Fig. and Extended Data Fig. ). However, under continuous dialysis, we also observe crystals structurally similar to Thorium Phosphide (Th 3 P 4 ) exhibiting distinct triakis tetrahedral habits, and this is also observed in simulation for certain values of λ D and volume fraction (ϕ p ) (Fig. and Extended Data Fig. ).
