DOI: 10.1017/jfm.2025.10865
Abstract: Abstract Surfactants are usually added in droplet-based systems to stabilise them. When their concentration exceeds the critical micelle concentration (CMC), they self-assemble into micelles, which act as reservoirs regulating the availability of monomers in the… read more here.
