Deciphering the Scattering of Mechanically Driven Polymers using Deep Learning
Lijie Ding, Chi-Huan Tung, Bobby G. Sumpter +2
We present a deep learning approach for analyzing two-dimensional scattering data of semiflexible polymers under external forces. In our framework, scattering functions are compres…
Switchable phonon diodes using nonlinear topological Maxwell lattices
Di Zhou, Jihong Ma, Kai Sun +2
Recent progress in topological mechanics have revealed a family of Maxwell lattices that exhibit topologically protected floppy edge modes. These modes lead to a strongly asymmetri…
Influence of Side Chain Isomerism on the Rigidity of Poly(3-alkylthiophenes) in Solutions Revealed by Neutron Scattering
William D. Hong, Christopher N. Lam, Yangyang Wang +5
Using small angle neutron scattering, we conducted a detailed structural study of poly(3-alkylthiophenes) dispersed in deuterated dicholorbenzene. The focus was placed on addressin…
Enhanced scattering induced by electrostatic correlations in concentrated solutions of salt-free dipolar and ionic polymers
Rajeev Kumar, Bradley Lokitz, Timothy E. Long +1
We present a generalized theory for studying static monomer density-density correlation function (structure factor) in concentrated solutions and melts of dipolar as well as ionic…
Comment on: "Relating Chain Conformations to Extensional Stress in Entangled Polymer Melts"
Wen-Sheng Xu, Christopher N. Lam, Jan-Michael Y. Carrillo +2
Based on non-equilibrium molecular dynamics simulations of entangled polymer melts, a recent Letter [Phys. Rev. Lett. , 047801 (2018), arXiv:1806.09509] claims that t…
Comment on "Edge-Induced Shear Banding in Entangled Polymeric Fluids" [arXiv: 1801.08798]
Yangyang Wang, Shi-Qing Wang
Based on numerical modeling with the diffusive Giesekus constitutive equation, a recent Letter [Phys. Rev. Lett. 120, 138002 (2018), arXiv:1801.08798] claimed that the experimental…
Scaling Behavior of Anisotropy Relaxation in Deformed Polymers
Christopher N. Lam, Wen-Sheng Xu, Wei-Ren Chen +12
Drawing an analogy to the paradigm of quasi-elastic neutron scattering, we present a general approach for quantitatively investigating the spatiotemporal dependence of structural a…
Strain Heterogeneity in Sheared Colloids Revealed by Neutron Scattering
Kevin Chen, Bin Wu, Guan-Rong Huang +2
Recent computational and theoretical studies have shown that the deformation of colloidal suspensions under a steady shear is highly heterogeneous at the particle level and demonst…
Dynamic Equivalence between Soft Star Polymers and Hard Spheres
Zhe Wang, Antonio Faraone, Panchao Yin +5
Understanding the dynamics of soft colloids, such as star polymers, dendrimers, and microgels, is of scientific and practical importance. It is known that the excluded volume effec…
Fingerprinting molecular relaxation in deformed polymers
Zhe Wang, Christopher N. Lam, Wei-Ren Chen +8
The flow and deformation of macromolecules is ubiquitous in nature and industry, and an understanding of this phenomenon at both macroscopic and microscopic length scales is of fun…
Local Elasticity in Nonlinear Rheology of Interacting Colloidal Glasses Revealed by Neutron Scattering and Rheometry
Zhe Wang, Takuya Iwashita, Lionel Porcar +7
The flow of colloidal suspensions is ubiquitous in nature and industry. Colloidal suspensions exhibit a wide range of rheological behavior, which should be closely related to the m…
Charge regulation and local dielectric function in planar polyelectrolyte brushes
Rajeev Kumar, Bobby G. Sumpter, S. Michael Kilbey
Understanding the effect of inhomogeneity on the charge regulation and dielectric properties, and how it depends on the conformational characteristics of the macromolecules is a lo…
Liquid-gas phase behavior of polydisperse dipolar hard-sphere fluid: Extended thermodynamic perturbation theory for central force associating potential
Yu. V. Kalyuzhnyi, S. Hlushak, P. T. Cummings
The liquid-gas phase diagram for polydisperse dipolar hard-sphere fluid with polydispersity in the hard-sphere size and dipolar moment is calculated using extension of the recently…
