Overview

  • [1] Kim, J., Lee, D., Shum, H., & Weitz, D. Adv. Mater. 20, 3239-3243 (2008).

Summary

Kim, Lee, Shum, and Weitz use solid particles in the place of surfactant molecules and qualitatively compare both methods of stabilizing emulsions.

The solid particles that the researchers fabricated look like two connected spheres of different radii (see figure 1). The reason for

Figure 1. Geometry of the fabricated particles. From figure 1 of [1].
