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

Chamber for Mechanical Testing in H2 with Observation by Neutron Scattering

June 1, 2017
Author(s)
Matthew J. Connolly, Peter E. Bradley, Andrew J. Slifka, Elizabeth S. Drexler
A gas-pressure chamber has been designed, constructed, and tested at a moderate pressure (3.4 MPa, 500 psi) and has the capability of mechanical loading of steel specimens for neutron scattering measurements. The chamber will allow a variety of in situ

Short Time and Structural Dynamics in Polypropylene Glycol Nanocomposite

June 1, 2017
Author(s)
Madhusudan Tyagi, R. Casalini, C. M. Roland
The dynamics of polypropylene glycol, both neat and attached to silica nanoparticles, were investigated using elastic neutron backscattering and dielectric spectroscopy. The mean square displacement measured by the former is suppressed by the particles at

Mechanistic Insights into the Formation of Porous Carbons from Gelatin

May 1, 2017
Author(s)
A. E. Danks, M. J. Hollamby, Boualem Hammouda, D. C. Fletcher, F. Johnston-Banks, S. E. Rogers, Z. Schnepp
Porous carbons are important for many applications. The biopolymer gelatin provides a simple route to functional carbon foams with77 multimodal porosity. In this paper, small angle neutron scattering is applied alongside other techniques to elucidate the

Effect of Phosphorylation on a Human-like Osteopontin Peptide

April 25, 2017
Author(s)
Samuel Lenton, Marco Grimaldo, Felix Roosen-Runge, Frank Schreiber, Tommy Nylander, Roger Clegg, Carl Holt, Michael Hartlein, Victoria Garcia Sakai, Tilo Seydel, Susana C. Marujo Teixeira
Osteopontin is a disordered phosphoprotein that is expressed in many species and tissues and has a range of distinct functions. A notable property of more highly phosphorylated isoforms of osteopontin is their ability to sequester nanoclusters of calcium
