WebMay 14, 2024 · The surface elasticity (which is quantitatively equal to half of the Gibbs elasticity) is the basis of coalescence inhibition (Christenson and Yaminsky 1995). Surface elasticity is increased by the use of electrolytes. Surface elasticity is proportional to the surface tension gradient and for a single electrolyte; this gives a good correlation ... WebThe Marangoni effect (also called the Gibbs–Marangoni effect) is the mass transfer along an interface between two phases due to a gradient of the surface tension. In the case of temperature dependence, this phenomenon may be called thermo-capillary convection (or Bénard–Marangoni convection).
