Size and shape fluctuations of ultrasoft colloids
Huarui Wu, Jing Song, Wei-Ren Chen +3
Ultrasoft colloidal particle fluctuates due to its flexibility. Such fluctuation is essential for colloidal structure and dynamics, but is challenging to quantify experimentally. W…
Experimental Search for Non-Newtonian Forces in the Nanometer Scale with Slow Neutrons
Y. Kamiya, R. Cubitt, L. Porcar +3
Improved limits for new gravity-like short-range interactions, in which a scattering potential is modeled by the Yukawa-type parametrization, have been obtained by measuring the an…
A Novel Experimental Approach for Nanostructure Analysis: Simultaneous Small Angle X-ray and Neutron Scattering (SAXS/SANS)
Ezzeldin Metwalli, Klaus Götz, Sebastian Lages +14
Exploiting small angle X-ray and neutron scattering (SAXS/SANS) on the same sample volume at the same time provides complementary nanoscale structural information at two different…
Kinky DNA in solution: Small angle scattering study of a nucleosome positioning sequence
Torben Schindler, Adrián González, Ramachandran Boopathi +10
DNA is a flexible molecule, but the degree of its flexibility is subject to debate. The commonly-accepted persistence length of Å is inconsistent with recent stu…
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…
