Small-Angle X-ray and Neutron Scattering Demonstrates that Cell-Free Expression Produces Properly Formed Disc-Shaped Nanolipoprotein Particles

December 20, 2017
Author(s)
Thomas E Cleveland, Wei He, Angela C. Evans, Nicholas O. Fischer, Matthew A. Coleman, Paul Butler
Nanolipoprotein particles (NLPs), composed of a membrane scaffold protein and lipids, have been used to support membrane proteins in a native-like bilayer environment for biochemical or structural studies. Traditionally, these NLPs have been prepared by

Clustering and Percolation in Suspensions of Carbon Black

November 22, 2017
Author(s)
Jeffrey J Richards, Julie Beth Hipp, John K Riley, Norman J. Wagner, Paul Butler
High-structured carbon fillers are ubiquitous as the conductive additive comprising suspension-based electrochemical storage technologies. Carbon black networks provide the necessary electric conductivity as well as mechanical percolation in the form of a

Clustering and Percolation in Suspensions of Carbon Black

Author(s)
Jeffrey J Richards, Julie Hipp, John K Riley, Norman J. Wagner, Paul Butler
In situ measurements are an increasingly important tool to inform the complex relationship between nanoscale properties and macroscopic measurements. These relationships can be used to inform the development of new materials, we have developed a SANS

Spin-Analyzed SANS for Soft Matter Applications

June 20, 2017
Author(s)
WangChun Chen, John Barker, Ronald L. Jones, Kathryn Krycka, Shannon Watson, Cedric Victor Lucien Gagnon, T. Perevozchivoka, Paul Butler, Thomas R. Gentile
The small angle neutron scattering (SANS) of nearly Q-independent nuclear spin-incoherent scattering from hydrogen present in most soft matter and biology samples may raise an issue in structure determination in certain soft matter applications. This is

PEE-PEO Block Copolymer Exchange Rate Between Mixed Micelles is Detergent and Temperature Activated

March 10, 2017
Author(s)
Allen B. Schantz, Patrick O. Saboe, Ian T. Sines, Hee-Young Lee, Kyle J. M. Bishop, Janna K. Maranas, Paul Butler, Manish Kumar
We examine the kinetics of polymer chain exchange between mixed polymer-detergent micelles, a system relevant to the synthesis of protein-containing biomimetic membranes. Although chain exchange between polymer aggregates in water occurs too slowly to

Atomistic Modelling of Scattering Data in the Collaborative Computational Project for Small Angle Scattering (CCP-SAS) 1

October 17, 2016
Author(s)
Stephen J. Perkins, David W. Wright, Hailiang Zhang, Emre H. Brookes, Jianhan Chen, Thomas C. Irving, Susan T. Krueger, David J. Barlow, Karen J. Edler, David J. Scott, Nicholas J. Terrill, Stephen M. King, Paul Butler, Joseph E. Curtis
In solution scattering, the major investment worldwide in multiuser X-ray synchrotrons and neutron sources have resulted in huge advances in the throughput and accuracy of the experimental measurements. Whilst closed-source non-atomistic analytical

Lightweight, flexible, high-performance carbon nanotube cables by scalable flow coating*

January 21, 2016
Author(s)
Nathan D. Orloff, Francesca Mirri, Aaron M. Forster, Rana NMN Ashkar, Robert Headrick, E. A. Bengio, Christian J. Long, April Choi, Yimin Luo, Angela R. Hight Walker, Paul Butler, Kalman D. Migler, Matteo Pasquali
Coaxial cables for data transmission are ubiquitously used in telecommunications, aerospace, automotive and robotics industries. Unfortunately, the metals used to make commercial cables are heavy and stiff. These undesirable traits are particularly

Wetting-Dewetting and Dispersion-Aggregation Transitions are Distinct for Polymer Grafted Nanoparticles in Chemically Dissimilar Polymer Matrix

August 26, 2015
Author(s)
Tyler B. Martin, Katrina Irene S. Mongcopa, Rana N. Ashkar, Paul Butler, Ramanan Krishnamoorti, Arthi Jayaraman
Simulations and experiments are conducted on polymer mixtures (or blends) containing polymer grafted nanoparticles in a chemically distinct polymer matrix, where the graft and matrix polymers exhibit attractive enthalpic interactions. Both coarse-grained
