(materials)
A thermodynamically stable dispersion of two immiscible liquids, stabilized by surfactants; it is typically clear because the dispersed droplets are less than 100 nanometers in diameter.

Summary: TEHRAN (FNA)- Iranian researchers at Ferdowsi University of Mashhad devised a new scheme for preparation of core-shell nanocrystals, by combining the microemulsion and ultrasonication methods, which features moderate synthesis conditions and does not require any surfactants.
Schulman et al have postulated that interfacial tension is a key process in microemulsion formation and that the main role of the surfactant is to reduce the interfacial tension to very low values [13, 14].
