Molecular Dynamics Simulation of Trimer Self-Assembly Under Shear

March 6, 2017

Author(s)

Raymond D. Mountain, Harold Hatch, Vincent K. Shen

The self-assembly of patchy trimer particles with one attractive bead and two repulsive beads is investigated with nonequilibrium molecular dynamics simulations in the presence of a velocity gradient, as would be produced by the application of a shear

Depletion-Driven Crystallization of Cubic Colloids Sedimented on a Surface

May 19, 2016

Author(s)

Harold W. Hatch, William P. Krekelberg, Steven D Hudson, Vincent K. Shen

Cubic colloids, sedimented on a surface and immersed in a solution of depletant molecules, were modeled with a family of shapes which smoothly varies from squares to circles. Using Wang-Landau simulations with expanded ensembles, we observe the formation

Self-Assembly of Trimer Colloids: Effect of shape and interaction range

April 5, 2016

Author(s)

Harold W. Hatch, Seung Y. Yang, Jeetain Mittal, Vincent K. Shen

Trimers with one attractive bead and two repulsive beads, similar to recently synthesized trimer patchy colloids, were simulated with flat-histogram Monte Carlo methods to obtain the stable self-assembled structures for different shapes and interaction

Computational Study of Trimer Self-Assembly and Fluid Phase Behavior

April 24, 2015

Author(s)

Harold W. Hatch, Vincent K. Shen, Jeetain Mittal

The fluid phase diagram of trimer particles composed of one central attractive bead and two repulsive beads was determined as a function of simple geometric parameters using flat-histogram Monte Carlo methods. A variety of self-assembled structures were
