Wall Migration and Shear-Induced Diffusion of Fluid Droplets in Emulsions

January 1, 2003
Author(s)
Steven D. Hudson
The spatial distribution of drops in multiphase flow through narrow passages is analyzed theoretically and experimentally. In simple shear between two plates, drops migrate away from the walls and concentrate towards the center of the gap. At steady state

Solvophobically Driven Self-Assembly of Chiral Supramolecular Dendrimers

December 1, 2002
Author(s)
Virgil Percec, A E. Dulcey, Y Miura, U Edlund, V S. Balagurusamy, Steven Hudson, H Duan, Paul A. Heiney
The self assembly in dilute solution of chiral supramolecular dendrimers is investigated by circular dichroism (CD) spectroscopy. These results are compared with analysis of the bulk state by CD spectroscopy x-ray diffraction electron diffraction and

Layered Droplet Microstructures in Sheared Emulsions: Finite-Size Effects

November 1, 2002
Author(s)
Jai A. Pathak, M C. Davis, Steven D. Hudson, Kalman D. Migler
We investigate the influence of confinement on the steady state microstructure of emulsions sheared between parallel plates, in a regime where the average droplet dimension is comparable to the gap width between the confining walls. Utilizing droplet

Self-Organization of Supramolecular Helical Dendrimers Into Complex Electronic Materials

September 1, 2002
Author(s)
Virgil Percec, A Rapp, Hans -. Spiess, Steven Hudson, H Duan, M Glodde, T K. Bera, Y Miura, I Shiyanovskaya, K D. Singer, V S. Balagurusamy, Paul A. Heiney, I Schnell
The discovery of electrical conduction in organic crystals and polymers has widened the range of potential optoelectronics materials, provided these exhibit sufficiently high charge carrier mobilities and are easy to make and process. Organic single

Structure Formation in Micro-Confined Polymeric Emulsions

August 1, 2002
Author(s)
Jai A. Pathak, Steven D. Hudson, Kalman D. Migler
Application of a shear field to a concentrated emulsion induces a complex spatial and temporal response. The behavior of a concentrated system is treated as an extrapolation of the well-understood behavior of isolated droplets (or of the behavior of two
