(a) The blow-up pressure against the viscosity ratio for PE 5 and for dispersed phases of: silicon oil (∆) (50 mPa s), hexadecane (○) (3.5 mPa s) and decane (□) (0.92 mPa s). (b,c) Screen shots, in which the black arrow and the dashed circle indicate the length of the neck (Ln) and the radius of the in-plane curvature (rc), respectively at 120 mbar (b) and at 900 mbar (c) for a hexadecane in water (+0.5 wt.% SDS) system.
