Nanoparticles in Layered Media

Project Details

Key findings

The samples used contained a high concentration of surfactant (soap-like) molecules. The chosen ingredients separate into two parts one concentrated in soap and the other not when they are warmed up. We found that adding small particles to these ingredients significantly alters this separation behaviour. In particular the process was radically slowed down and contained some completely new features.
We also used a recently developed x-ray technique to study the motion of complex samples in time. We found that the motion was dominated by occasional large rearrangements rather than by a succession of small changes. The changes we focused on are similar to "shelf life" problems that occur in many commercial products that have a gel / thick liquid consistency.
