Dynamic Heterogeneity and Collective Motion in Star Polymer Melts

Jack F. Douglas, Jinpeng Fan, Hamed Emamy, Francis W. Starr, Alexandros Chremos
While glass formation of linear chain polymers has been widely explored, comparatively little is known about glass formation in star polymer melts. We study the

Superionic UO2: A Model Anharmonic Crystalline Material

Jack F. Douglas, Hao Zhang, Xinyi Wang, Alexandros Chremos
Crystalline materials at elevated temperatures and pressures can exhibit properties more reminiscent of simple liquids than ideal crystalline materials, an

Hidden Hyperuniformity in Bottlebrush Polymer Melts

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

Polyelectrolyte association and solvation

Alexandros Chremos, Jack F. Douglas
There has been significant interest in the tendency of highly charged particles having the same charge to form dynamic clusters in solution, but an accepted

Free Surface Relaxations of Star-Shaped Polymer Films

Alexandros Chremos, Bradley R. Frieberg, Emmanouil Glynos, Kyle Johnson, Hengxi Yang, Suresh Narayanan, Peter F. Green, Georgios Sakellariou
X-ray photon correlation spectroscopy (XPCS) studies show that the viscosities of thin film linear chain polymers at temperatures sufficiently high above the
