Microscale Mapping of Structure and Stress in Barium Titanate

April 19, 2020
Author(s)
Jane A. Howell, Mark D. Vaudin, Lawrence Henry Friedman, Robert F. Cook
Cross-correlation of electron backscatter diffraction (EBSD) patterns was used to generate rotation, strain, and stress maps of single-crystal tetragonal barium titanate (BaTiO3) containing isolated, small, sub-micrometer a domains separated from a c-

Industry Review of Distributed Production in Discrete Manufacturing

April 18, 2020
Author(s)
Moneer M. Helu, William Sobel, Saigopal Nelaturi, Russell Waddell, Scott Hibbard
Distributed production paradigms have grown in discrete manufacturing as discrete products are increasingly made by global, distributed networks. Current challenges faced by discrete manufacturing, such as increased globalization, market volatility

Certification of Standard Reference Material(R) 1450e Fibrous Glass Board

April 17, 2020
Author(s)
Robert R. Zarr, Nathanael A. Heckert
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450e, Fibrous Glass Board. The meas-urements have been conducted in accordance with a randomized full factorial

Energy-Efficient SWIPT-Empowered D2D ModeSelection

April 16, 2020
Author(s)
Hamid Gharavi
While mode selection has been envisioned as the most cost-effective way to address the interference issue in Device-to-Device (D2D) communications, existing works have been largely conducted without consideration of the energy depletion of devices. In this

Impact of Growth Kinetics on the Interface Morphology and Magnetization in La 1/3 Sr 2/3 FeO 3 /La 2/3 Sr 1/3 MnO 3 Heterostructures

April 17, 2020
Author(s)
M. Waschk, A. Sarkar, J. Barthel, J. Voigt, S. Schroder, P. Zakalek, M. Schmitz, Brian Kirby, S. Putter, J. Schubert, T. Bruckel
The ability to create atomically perfect, epitaxial heterostructures of correlated complex perovskite oxides using state-of-art thin film deposition techniques has generated new physical phenomena at engineered interfaces. Here we report on the impact of

NVLAP Efficiency of Electric Motors

April 17, 2020
Author(s)
Timothy W. Rasinski
NIST Handbook 150-10, NVLAP Efficiency of Electric Motors, presents the technical requirements and guidance for the accreditation of laboratories under the NVLAP Efficiency of Electric Motors laboratory accreditation program.

Static Analyzers: Seat Belts for Your Code

April 17, 2020
Author(s)
Paul E. Black
Just as seat belt use is wide spread, we argue that the use static analysis should be part of ethical software development. We explain some of the procedures of the four Static Analysis Tool Expositions (SATE), and some of the lessons we learned

Anisotropic Effect of a Magnetic Field on the Neutron Spin Resonance in FeSe

April 16, 2020
Author(s)
Tong Chen, Youzhe Chen, David W. Tam, Bin Gao, Yiming Qiu, Astrid Schneidewind, Igor Radelytskyi, Karel Prokes, Songxue Chi, Masaaki Matsuda, Collin L. Broholm, Pengcheng Dai
We use inelastic neutron scattering to study the effect of a magnetic field on the neutron spin resonance (Er = 3.6 meV) of superconducting FeSe (Tc = 9 K). While a field aligned along the in-plane direction broadens and suppresses the resonance, a c-axis

Development and Validation of Small Punch Testing at NIST

April 16, 2020
Author(s)
Enrico Lucon, Jake T. Benzing, Nikolas W. Hrabe
Small Punch (SP) testing is a methodology that uses tiny disks (generally 8 mm in diameter and 0.5 mm thick) to estimate mechanical properties of metallic materials, such as tensile properties, fracture toughness, and ductile-to-brittle transition

Microwave radiometer instability due to infrequent calibration

April 16, 2020
Author(s)
Kevin J. Coakley, Jolene D. Splett, Dave K. Walker, Mustafa Aksoy, Paul E. Racette
We directly quantify the effect of infrequent calibration on the stability of microwave radiometer temperature measurements (where a power measurement for the unknown source is acquired at a fixed time but calibration data are acquired at variable earlier

Quantum Logic Spectroscopy with Ions in Thermal Motion

April 16, 2020
Author(s)
Daniel Kienzler, Yong Wan, Stephen Erickson, Jenny Wu, Andrew C. Wilson, David J. Wineland, Dietrich Leibfried
A mixed-species geometric phase gate has been proposed for implementing quantum logic spectroscopy on trapped ions, which combines probe and information transfer from the spectroscopy to the logic ion in a single pulse. We experimentally realize this

Quasi-elastic Neutron Scattering Measurement of Hydrogen Diffusion in a Graphene Oxide Framework

April 16, 2020
Author(s)
Matthew J. Connolly, Z. N. Buck, Carlos Wexler, Joseph C. Schaeperkoetter, H. Taub, Andrew Gillespie, Helmut Kaiser
We present quasielastic neutron scattering (QENS) spectra from molecular hydrogen adsorbed in GOF. The measurements probed the motion of adsorbed hydrogen as a function of pressure, in order to understand the relationship between the motion of adsorbed

Author(s)
Benjamin W. Caplins, Paul T. Blanchard, Ann C. Chiaramonti Debay, David R. Diercks, Luis Miaja Avila, Norman A. Sanford
Improvements in the mass resolution of a mass spectrometer directly correlate to improvements in peak identification and quantification. Here we describe a post-processing technique developed to increase the quality of mass spectra of strongly insulating
