Correct Use of the Lifshitz-Slyosov-Wagner Expression for the   Calculation of the Average Radius of an Oil-In-Water (o/w) Emulsion Subject   to Coalescence
  The analytic expression proposed by Lifshitz-Slyozov and Wagner (LSW theory) for the linear variation of the cube average radius (R3) of an emulsion as function of time (t) is commonly used to appraise the effect of Ostwald ripening. However, we proved here both experimentally and theoretically that such approach is incorrect in those cases in which the coalescence of the drops cannot be prevented. In this event, the expression of LSW should be corrected in order to account for the actual average radius of the emulsion at each time, and instead of the radius predicted by the equations of LSW without consideration of the coalescence process.
