Research of Brad Frounfelker and Gokul Kalur.
Wormy micelles are flexible, polymer-like chains formed by self-assembly of surfactants. When sheared, the chains align and the sample becomes birefringent, but this goes away when the shear is stopped. This movie shows an unusual micellar fluid that remains intensely birefringent long after the shear is stopped. Shih-Huang Tung and Bani Cipriano also contributed to this work. |
