Sheared Foam as a Supercooled Liquid?

January 1, 2000
Author(s)
Stephen A. Langer, A J. Liu
We conduct numerical simulations on a simple model of a two-dimensional steady-state sheared foam, and define a quantity Γ that measures pressure fluctuations in the constant-area system. This quantity reduces to the temperature in an equilibrium system

Single Fiber Composites: A New Methodology for Determining Interfacial Shear Strength

January 1, 2000
Author(s)
Gale A. Holmes, Donald L. Hunston, Walter G. McDonough, R C. Peterson
One of the critical factors controlling the long-term performance and durability of composites in structural applications is the interfacial shear strength (IFSS). The single fiber composite (SFC) test has been viewed by many as the best test for

Size Invariance of Polyelectrolyte Dendrimers

January 1, 2000
Author(s)
G Nisato, R Ivkov, Eric J. Amis
In order to quantify the swelling response of polyelectrolyte dendrimers in aqueous solutions as affected by changes in solution conditions, we have studied generation 8 poly(amido amine) (PAMAM) dendrimers in D2O using small angle neutron scattering (SANS

Solidification Microstructures: Recent Developments, Future Directions

January 1, 2000
Author(s)
William J. Boettinger, Sam R. Coriell, A L. Greer, A N. Karma, W Kurz, M Rappaz, R Trivedi
This review is intended to critically evaluate the latest status of solidification science and to discuss and propose future directions of research in this technologically important area. It is an updated version of the outcome of the 1998 Zermatt Workshop
