Spatial correlations of entangled polymer dynamics
Jihong Ma, Jan-Michael Y. Carrillo, Changwoo Do +6
The spatial correlations of entangled polymer dynamics are examined by molecular dynamics simulations and neutron spin-echo spectroscopy. Due to the soft nature of topological cons…
Step edge-mediated assembly of periodic arrays of long graphene nanoribbons on Au(111)
Chuanxu Ma, Zhongcan Xiao, Wenchang Lu +4
The influence of substrate steps on the bottom-up synthesis of atomically precise graphene nanoribbons (GNRs) on an Au(111) surface is investigated. A straight surface step is foun…
Direct writing of heterostructures in single atomically precise graphene nanoribbons
Chuanxu Ma, Zhongcan Xiao, Jingsong Huang +6
Precision control of interfacial structures and electronic properties is the key to the realization of functional heterostructures. Here, utilizing the scanning tunneling microscop…
Design of Atomically Precise Nanoscale Negative Differential Resistance Devices
Zhongcan Xiao, Chuanxu Ma, Jingsong Huang +6
Down-scaling device dimensions to the nanometer range raises significant challenges to traditional device design, due to potential current leakage across nanoscale dimensions and t…
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…
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…
Scattering from Star Polymers including Excluded Volume Effects
Xin Li, Changwoo Do, Yun Liu +4
In this work we present a new model for the form factor of a star polymer consisting of self-avoiding branches. This new model incorporates excluded volume effects and is derived f…
Influence of Molecular Solvation on the Conformation of Star Polymers
Xin Li, Lionel Porcar, Luis E. Sánchez-Diáz +7
We have used neutron scattering to investigate the influence of concentration on the conformation of a star polymer. By varying the contrast between the solvent and isotopically la…
