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…
Scattering from Colloid-Polymer Conjugates with Excluded Volume Effect
Xin Li, Christopher N. Lam, Luis E. Sánchez-Diáz +3
In this work we present scattering functions of conjugates consisting of a colloid particle and a self-avoiding polymer chain. This model is directly derived from the two point cor…
Corrections for the Geometric Distortion of the Tube Detectors on SANS Instruments at ORNL
Lilin He, Changwoo Do, Shuo Qian +4
The small-angle neutron scattering instruments at the Oak Ridge National Laboratory High Flux Isotope Reactor recently upgraded the area detectors from the large, single volume cro…
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…
Phase behavior under a non-centrosymmetric interaction: shifted charge colloids investigated by Monte Carlo simulation
Luis E. Sánchez-Díaz, Chwen-Yang Shew, Xin Li +3
Using Monte Carlo simulations, we investigate the structural characteristics of an interacting hard sphere system with shifted charge to elucidate the effect of the non-centrosymme…
Dynamical Crossover in Soft Colloids below the Overlap Concentration
Xin Li, Luis E. Sánchez-Diáz, Bin Wu +8
The dynamics of soft colloids in solutions is characterized by internal collective motion as well as center-of-mass diffusion. Using neutron scattering we demonstrate that the comp…
Understanding inelastically scattered neutrons from water on a time-of-flight small-angle neutron scattering (SANS) instrument
Changwoo Do, William T. Heller, Christopher Stanley +3
It is generally assumed by most of the small-angle neutron scattering (SANS) user community that a neutrons energy is unchanged during SANS measurements. Here, the scattering from…
