systems was determined fitting the values of the interfacial density profile of the water to the hyperbolic tangent function defined by the Eq. (5)”. Here, must say: “The position of the GDS in the CO2(gas)/SDS/water/SDS/CO2(gas) systems was determined fitting the values of the interfacial density profile of the water to the hyperbolic tangent function defined by the Eq. S1 (see Supporting information)”. The authors would like to apologise for any inconvenience caused.
