Liquid Nanodroplets Spreading on Chemically Patterned Surfaces
Gary S. Grest, David R. Heine, Edmund B. Webb
Controlling the spatial distribution of liquid droplets on surfaces via surface energy patterning can be used to control material delivery to specified regions via selective liquid…
Diverse Spreading Behavior of Binary Polymer Nanodroplets
David R. Heine, Gary S. Grest, Edmund B. Webb
Molecular dynamics simulations are used to study the spreading of binary polymer nanodroplets in a cylindrical geometry. The polymers, described by the bead-spring model, spread on…
Surface Wetting of Liquid Nanodroplets
David R. Heine, Gary S. Grest, Edmund B. Webb
The spreading of liquid nanodroplets of different initial radii is studied using molecular dynamics simulation. Results for two distinct systems, Pb on Cu(111), which is no…
Spreading Dynamics of Polymer Nanodroplets in Cylindrical Geometries
David R. Heine, Gary S. Grest, Edmund B. Webb
The spreading of one- and two-component polymer nanodroplets is studied using molecular dynamics simulation in a cylindrical geometry. The droplets consist of polymer chains of len…
Spreading Dynamics of Polymer Nanodroplets
David R. Heine, Gary S. Grest, Edmund B. Webb
The spreading of polymer droplets is studied using molecular dynamics simulations. To study the dynamics of both the precursor foot and the bulk droplet, large drops of ~200,000 mo…
Invariance of density correlations with charge density in polyelectrolyte solutions
James P. Donley, David R. Heine, David T. Wu
We present a theory for the equilibrium structure of polyelectrolyte solutions. The main element is a simple, new optimization scheme that allows theories such as the random phase…
