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

Rafting and Elastoplastic Deformation of Superalloys Studied by Neutron Di raction

June 1, 2017
Author(s)
James Coakley, Eric Lass, Dong Ma, Matthew Frost, David N. Seidman, David C. Dunand, Howard Stone
The rafting of monocrystalline Ni- and Co-based superalloys has been studied by neutron diffractometry. The nature of rafting is shown experimentally to be dependent upon both the lattice parameter misfit and the difference in phase stiffnesses. The 900 ◦C

Rapid and reliable steroid hormone profiling in Tursiops truncatus blubber using liquid chromatography tandem mass spectrometry (LC-MS/MS)

June 1, 2017
Author(s)
Ashley S. Boggs-Russell, Tracey B. Schock, Thomas M. Galligan, Wayne E. McFee, Jeanine S. Morey, Lori Schwacke, John R. Kucklick
Monitoring of marine mammal steroid hormone status using matrices alternative to blood is desirable due to the ability to remotely collect samples which minimizes stress. However, measurement techniques in alternative matrices such as blubber described to

Role of Rheology in Achieving Successful Concrete Performance

June 1, 2017
Author(s)
Chiara F. Ferraris
Workability is one of the most important properties of concrete as it determines how easily the material can be placed. Workability affects many aspects of a concrete construction, including productivity (e.g. casting rate), processing (e.g. finishing)

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
