Abstract Aerosols are significant to the Earth’s climate, with nearly all atmospheric aerosols containing organic compounds that often contain both hydrophilic and hydrophobic parts. However, nature of how these arranged within an aerosol droplet remains unknown. Here we demonstrate fatty acids in proxies for self-assemble into highly ordered three-dimensional nanostructures may have implications environmentally important processes. Acoustically trapped droplets oleic acid/sodium oleate...
