Research Areas

• Surfactants and Colloids

Almost all engineering processes involve the transport of material across an interface. These interfacial regions are characterized by changes of composition or density over length scales comparable to molecular dimensions.

Similarly, the composition and structure of a single phase can vary markedly over small distances. Examples are liquid crystals, microemulsions and micelles, some polymeric solutions, vesicles, emulsions, and protein dispersions. The physical properties of such complex fluids make them useful in a multitude of applications. The best use of these materials, however, requires knowledge of the arrangement of the material structure on a molecular scale.

With the goal of developing such an understanding, we have studied several microemulsions, micelles, and vesicular dispersions as well as concentrated colloidal suspensions. The main focus of our work was experimental, but also involved substantial theoretical and computational efforts.
