Influence of solvation on the structure of highly charged nanoparticle salt-free solutions
March 08, 2019
Author(s):
Alexandros Chremos, Jack F. Douglas
We investigate the influence of ion and nanoparticle solvation on the structure of aqueous salt- free solution of highly charged nanoparticles. In particular,...
Hidden Hyperuniformity in Bottlebrush Polymer Melts
December 21, 2018
Author(s):
Alexandros Chremos, Jack F. Douglas
We show that the backbone chains of bottlebrush polymer melts exhibit a hidden hyperuniform packing over a wide temperature range above glass transition...

Polymer films provide a versatile “plastic” material in which complex functional relief patterns can be imprinted with a resolution down to tens of...
Competitive solvation effects in polyelectrolyte solutions
August 01, 2018
Author(s):
Alexandros Chremos, Jack F. Douglas
An understanding of the solution properties and phase behavior of natural and synthetic polyelectrolytes requires an understanding of the competitive...
A Comparative Study of Thermodynamic, Conformational, and Packing Properties of Bottlebrush with Star and Ring Polymer Melts
July 27, 2018
Author(s):
Alexandros Chremos, Jack F. Douglas
Thermodynamic, conformational, and structure properties of bottlebrush polymer melts are investigated with molecular dynamics simulations and compared to...
