In a mixture with multiple dissolved solutes, the diffusivity depends on the density of all components. Interactions among species may give rise to phase separation; the resulting microstructure affects diffusive transport. This mechanism may play an important role in diffusion within cell membranes. We explore this via Monte Carlo simulation of the two-dimensional lattice gas. A grid is populated by “blocker” particles. “Tracer” particles are released on one side of the grid and diffuse via nearest-neighbor hops; particles that reach the opposite side exit the system. Ising-like interactions of all particles are taken into account via the Metropolis algorithm. The interactions cause blocker particles to attract, aggregating into clusters at low temperature; tracer is miscible with the surrounding solution. At high temperature, both species are miscible. We examine how flux affects microstructure, and how microstructure affects transport. These results yield insight into fundamental mechanisms affecting transport in crowded mixtures.
