Homogeneous Binary Nucleation Theory and the Structure of Binary Nanodroplets
The structure of a critical nucleus or a larger post-critical droplet refers to the spatial distributions of the different chemical species within the droplet. Structure directly affects the free energy of formation of droplets. This has a strong effect on the nucleation rate as well as on the rates of droplet growth and evaporation. Structure also affects how aerosol droplets interact with their environment, influencing phenomena such as heterogeneous chemistry, trace gas adsorbtion and uptake, and the radiative properties of larger droplets. This paper briefly reviews recent advances in understanding the structure of critical nuclei in highly nonideal binary systems. It then focuses on recent theoretical work to predict the structure of larger binary nanodroplets using density functional theory (DFT) and lattice Monte Carlo (MC) simulations of model aqueous-organic mixtures.
