Thermodynamic-Dynamic Interrelations in Glass-Forming Polymer Fluids
Xiaolei Xu, Jack F. Douglas, Wen-Sheng Xu
We utilize the lattice cluster theory (LCT) of polymer fluids to show that the configurational entropy, enthalpy, and internal energy are all closely interrelated, as suggested by…
Dynamics of Associative Polymers with High Density of Reversible Bonds
Shifeng Nian, Shalin Patil, Siteng Zhang +6
We design and synthesize unentangled associative polymers carrying unprecedented high fractions of stickers, up to eight per Kuhn segment, that can form strong pairwise hydrogen bo…
Equation of State and Entropy Theory Approach to Thermodynamic Scaling in Polymeric Glass-Forming Liquids
Jack F. Douglas, Wen-Sheng Xu
We show that thermodynamic scaling can be derived by combining the Murnaghan equation of state (EOS) with the generalized entropy theory (GET) of glass formation. In our theory, th…
Polymer Glass Formation: Role of Activation Free Energy, Configurational Entropy, and Collective Motion
Wen-Sheng Xu, Jack F. Douglas, Zhao-Yan Sun
We provide a perspective on polymer glass formation, with an emphasis on models in which the fluid entropy and collective particle motion dominate the theoretical description and d…
Dynamics in two-dimensional glassy systems of crowded Penrose kites
Yan-Wei Li, Zi-Qi Li, Zhang-Lin Hou +4
We investigate the translational and rotational relaxation dynamics of a crowded two-dimensional system of monodisperse Penrose kites, in which crystallization, quasi-crystallizati…
Long-wavelength fluctuations and anomalous dynamics in two-dimensional liquids
Yanwei Li, Chandan K. Mishra, Zhaoyan Sun +4
Long-wavelength Mermin-Wagner fluctuations prevent the existence of translational long-range order, in two-dimensional systems at finite temperature. Their dynamical signature, whi…
Structural Signature of Slow and Heterogeneous Dynamics in Glass-Forming Liquids
Yan-Wei Li, You-Liang Zhu, Zhao-Yan Sun
One of the central problems of the liquid-glass transition is whether there is a structural signature that can qualitatively distinguish different dynamic behaviors at different de…
Relaxation dynamics in a binary hard-ellipse liquid
Wen-Sheng Xu, Zhao-Yan Sun, Li-Jia An
Structural relaxation in binary hard spherical particles has been shown recently to exhibit a wealth of remarkable features when size disparity or mixture's composition is varied.…
Lamellar thickness and stretching temperature dependency of cavitation in semicrystalline polymers
Yaotao Wang, Zhiyong Jiang, Lianlian Fu +2
Polybutene-1 (PB-1), a typical semicrystalline polymer, in its stable form I shows a peculiar temperature dependent strain-whitening behavior when being stretched at different temp…
Hard ellipses: Equation of state, structure and self-diffusion
Wen-Sheng Xu, Yan-Wei Li, Zhao-Yan Sun +1
We present an event-driven molecular dynamics study for hard ellipses and assess the effects of aspect ratio and area fraction on their physical properties. For state points in the…
Effect of attractions on correlation length scales in a glass-forming liquid
Wen-Sheng Xu, Zhao-Yan Sun, Li-Jia An
There is growing evidence that slow dynamics and dynamic heterogeneity possess structural signatures in glass-forming liquids. However, even in the weakly frustrated glass-forming…
Structure, compressibility factor and dynamics of highly size-asymmetric binary hard-disk liquids
Wen-Sheng Xu, Zhao-Yan Sun, Li-Jia An
By using event-driven molecular dynamics simulation, we investigate effects of varying the area fraction of the smaller component on structure, compressibility factor and dynamics…
Dynamics and correlation length scales of a glass-forming liquid in quiescent and sheared conditions
Wen-Sheng Xu, Zhao-Yan Sun, Li-Jia An
We numerically study dynamics and correlation length scales of a colloidal liquid in both quiescent and sheared conditions to further understand the origin of slow dynamics and dyn…
Diffusive redistribution of small spheres in crystallization of highly asymmetric binary hard-sphere mixtures
Wen-Sheng Xu, Zhao-Yan Sun, Li-Jia An
We report a molecular dynamics study of crystallization in highly asymmetric binary hard-sphere mixtures, in which the large spheres can form a crystal phase while the small ones r…
First-Passage Time Distribution and Non-Markovian Diffusion Dynamics of Protein Folding
Chi-Lun Lee, George Stell, Jin Wang
We study the kinetics of protein folding via statistical energy landscape theory. We concentrate on the local-connectivity case, where the configurational changes can only occur am…
