Wrapping up water : Two non‐fluorinated CO 2 ‐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 D 2 O nanodroplets (red), stabilized by surfactant interfacial monolayers (lines), and dispersed in CO 2 (yellow in the schematic scattering length density (sld) profile).
