Dynamical clustering of counterions on flexible polyelectrolytes

Autor: Lo, Tak Shing, Khusid, Boris, Koplik, Joel

Molecular dynamics simulations are used to study the local dynamics of counterion-charged polymer association at charge densities above and below the counterion condensation threshold. Surprisingly, the counterions form weakly-interacting clusters wh

Interfacial Slip in Sheared Polymer Blends

Autor: Lo, Tak Shing, Mihajlovic, Maja, Shnidman, Yitzhak, Li, Wentao, Gersappe, Dilip

We have developed a dynamic self-consistent field theory, without any adjustable parameters, for unentangled polymer blends under shear. Our model accounts for the interaction between polymers, and enables one to compute the evolution of the local rh

A Self-Consistent Field Study of Interfacial Dynamics in Unentangled Homopolymer Fluids in a Sheared Channel

Autor: Mihajlovic, Maja, Lo, Tak Shing, Shnidman, Yitzhak

In a preceding paper, we have presented a general lattice formulation of the dynamic self-consistent field (DSCF) theory for inhomogeneous, unentangled homopolymer fluids. Here we apply the DSCF theory to study both transient and steady-state interfa

Dynamic Self-Consistent Field Theory for Unentangled Homopolymer Fluids

Autor: Mihajlovic, Maja, Lo, Tak Shing, Shnidman, Yitzhak

We present a lattice formulation of a dynamic self-consistent field (DSCF) theory that is capable of resolving interfacial structure, dynamics and rheology in inhomogeneous, compressible melts and blends of unentangled homopolymer chains. The joint p

Phase-field modeling of microstructural pattern formation during directional solidification of peritectic alloys without morphological instability

Autor: Lo, Tak Shing, Karma, Alain, Plapp, Mathis

Publikováno v: Phys. Rev. E 63, 031504 (2001)

During the directional solidification of peritectic alloys, two stable solid phases (parent and peritectic) grow competitively into a metastable liquid phase of larger impurity content than either solid phase. When the parent or both solid phases are
