摘要
Wrapping up water: Two non-fluorinated CO2-philic surfactants are used to generate water in carbon dioxide microemulsion dispersions. Detailed analyses of high-pressure small-angle neutron scattering data provide evidence for formation of spherical D2O nanodroplets (red), stabilized by surfactant interfacial monolayers (lines), and dispersed in CO2 (yellow in the schematic scattering length density (sld) profile).
