Free energies values for the formation of a nanobubble and an interfacial nanobubble of radius Rnb in CH2Br2 under negative pressure;
AB = ΔΕhom = 2.34 × 10−18J and CB = ΔΕhet = 1.56 × 10−19 J. Heterogeneous nucleation requires about the 1/15th of homogeneous nucleation energy to form an INB of Rnb = 37 Å with lateral size α/2 = Rnb sin(π−133o) = 27 Å.
