Sažetak

Interfacial tensions were measured as a function of the
curvature of the interface in liquid ternary, two-phase systems at
25 °c. The systems were chosen so that the phase on the concave
side of the interface ( = the inner phase = the droplet) consisted
mainly of one of the components. When this compound is a nonpolar
or polar, non-hydrogen bonding liquid the interfacial tension
is almost independent of curvature, but when the inner phase is
a hydrogen bonding liquid the interfacial tension a varies with
the radius of curvature. The experimental method consisted in
determining the time taken for a supersaturated solution to
become turbid, this time being of the order of 1 millisecond.
