Improving Measurement for Smokestack Emissions - Workshop Summary

September 21, 2018
Author(s)
Rodney A. Bryant, Aaron N. Johnson, John D. Wright, Tamae M. Wong, James R. Whetstone, Michael R. Moldover, Iosif I. Shinder, Scott Swiggard, Chris Gunning, David Elam, Tom Martz, Eric Harman, David Nuckols, Liang Zhang, Woong Kang, Salvator Vigil
The complex flow conditions inherent in power plant smokestacks make accurate flow measurements challenging, which in turn limits the accuracy of hazardous emissions measurements. While stack composition measurements are assessed daily via comparison to a

Natural Alteration of 6Li Neutron Shielding Glass

September 21, 2018
Author(s)
Jamie L. Weaver, Danyal J. Turkoglu
Li-6 alumino-silicate glass, a neutron shielding material, has been studied to determine if and to what extent it alters under natural conditions. Analyses included neutron depth profiling, prompt gamma activation analysis, x-ray diffraction, and scanning

On the mechanisms and the characterization of the pulsed electron grafting of styrene onto poly(tetrafluoroethylene-co-hexafluoropropylene) to synthesize a polymer electrolyte membrane

September 21, 2018
Author(s)
Byung N. Kim, Alia Weaver, Marina Chumakov, Ileana M. Pazos, Dianne L. Poster, Karen Gaskell, Do H. Han, Gunther Scherer, Michael A. Yandrasits, Byung C. Lee, Mohamad Al-Sheikhly
During the pulsed-electron beam direct grafting of neat styrene onto poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP) substrate, the radiolytically-produced styryl and carbon-centered FEP radicals undergo various desired and undesired competing

Structure, Rheology, and Microrheology of Wormlike Micelles made of PB-PEO Diblock Copolymers

September 21, 2018
Author(s)
Antonio Tavera-Vazquez, Brisa Arenas-Gomez, Cristina Garza, Yun Liu, Rolando Castillo
A diblock copolymer made of poly(but-2-ene-1,4-diyl)-block-poly(oxyethylene), with a degree of polymerization of the polybutadiene and polyethylene blocks of 37 and 57, respectively, self-assembles in water as worm-like micelles determined with small angle

Atom Probe Tomography Analysis of the Reference Zircon GJ-1: A Round-Robin Experiment

September 20, 2018
Author(s)
Ann C. Chiaramonti Debay, Paul T. Blanchard, Alexandre La Fontaine, Florent Exertier, Sandra Piazolo, Elena Belousova, Zirong Peng, Baptiste Gault, David W. Saxey, Denis Fougerouse, Steven Reddy, Julie Cairney
In recent years, atom probe tomography (APT) has been increasingly used to study minerals, and in particular Zircons. The mineral Zircon (ZrSiO4) is ideally suited for geochronology by utilising the U-Th-Pb isotope systems, and trace element compositions

Defect-Driven Extreme Magnetoresistance in an I-Mn-V Semiconductor

September 20, 2018
Author(s)
Junjie Yang, Aaron Wegner, Craig Brown, Despina Louca
Semiconducting electronics have been transformed in part due to progress in spin polarized transport. Central to modern day spintronics, contemporary magnetoresistive components are based on ferromagnetic multilayers. New directions in the search for the

A Method for Measuring the Quantity of Drugs on Surfaces in a Forensic Laboratory

September 19, 2018
Author(s)
Edward R. Sisco, Marcela N. Najarro, Amber Burns
While background studies have been commonplace in many occupational fields for a long time, attempts to understand the chemical background in forensics labs has been largely understudied. However, given the increasing sensitivity of instrumentation and

An optical Bragg scattering readout for simultaneous detection of all low-order mechanical modes of gallium nitride nanowires in nanowire arrays

September 19, 2018
Author(s)
Kristine A. Bertness, John P. Houlton, Matthew D. Brubaker, Charles T. Rogers
We report the use of optical Bragg scattering and homodyne interferometry to simultaneously measure all the first order cantilever-mode mechanical resonance frequencies and quality factors (Q) of gallium nitride nanowires (GaN NWs) in 100 NW periodic

Phase-Sensitive Small-Angle Neutron Scattering Experiment

September 19, 2018
Author(s)
Erik Brok, Kathryn L. Krycka, Erika C. Vreeland, Andrew Gomez, Dale L. Huber, Charles Majkrzak
Small angle neutron scattering is a useful technique for determining the structure of biomolecules in solution. However, because of the well-known problem that the phase of the scattered wave is lost in scattering experiments, unambiguous structural

Reference Correlations for the Thermal Conductivity of 13 Inorganic Molten Salts

September 19, 2018
Author(s)
Ch. D. Chliatzou, Marc J. Assael, K.D. Antoniadis, Marcia L. Huber, William A. Wakeham
The available experimental data for the thermal conductivity of the inorganic molten salts (KNO3, LiNO3, NaNO3, KBr, NaBr, RbBr, CsCl, KCl, LiCl, NaCl, RbCl, NaI, and RbI), have been critically examined with the intention of establishing thermal

2017 NIST/ITL Cybersecurity Program: Annual Report

September 18, 2018
Author(s)
Patrick D. O'Reilly, Kristina G. Rigopoulos, Gregory A. Witte, Larry Feldman
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry
