Plasma Charge-Density Ratios in a Dusty Plasma

February 1, 2000
Author(s)
M A. Childs, Alan Gallagher
It is shown that particle diffusion in the afterglow of a dusty plasma can be used to establish several properties of the active plasma. Specifically, the ratio of the average mass of light negative and positive ions, and a limit for the ratio of electron

Diffusion in Partially Saturated Porous Materials

October 1, 1999
Author(s)
Nicos Martys
The diffusive transport of ions in two classes of porous media was studied as a function of fluid saturation and wetting properties. A lattice Boltzmann method was used to model phase separation of a binary mixture, including wetting effects, in porous

Flammability of Polystyrene-Clay Nanocomposites

January 1, 2000
Author(s)
A B. Morgan, Jeffrey W. Gilman, Richard H. Harris Jr., C L. Jackson, C A. Wilkie, J Zhu
Research in the area of condensed phase flame retardants for polymers usually builds upon existing technologies, such as metal hydroxides (alumina, magnesium hydroxide) or phosphorus based materials. However, these materials tend to weaken mechanical
