Calibration Procedures for Weights and Measures Laboratories

May 29, 2019
Author(s)
Georgia L. Harris
This publication contains standard operating procedures for calibrations that were not previously published in other NIST Office of Weights and Measures publications and are included here in support of weights and measures laboratory program requirements

Single-scan acquisition of multiple multidimensional spectra

May 29, 2019
Author(s)
Travis M. Autry, Galan Moody, James M. Fraser, Corey A. McDonald, Richard P. Mirin, Kevin L. Silverman
Multidimensional coherent spectroscopy is a powerful tool for understanding the ultrafast dynamics of complex quantum systems. To fully characterize the nonlinear optical response of a system, multiple pulse sequences must be recorded and quantitatively

S. Bettler, F. Landolt, O. M. Aksoy, Z. Yan, S. Gvasaliya, Yiming Qiu, E. Ressouche, K. Beauvois, S. Raymond, A. N. Ponomaryov, S. A. Zvyagin, A. Zheludev
Single crystal neutron diffraction, inelastic neutron scattering and electron spin resonance experiments are used to study the magnetic structure and spin waves in Pb 2VO(PO 4) 2, a prototypical layered S =1/2 ferromagnet with frustrating next nearest

Graphical Methods in Device-Independent Quantum Cryptography

May 27, 2019
Author(s)
Spencer J. Breiner, Carl A. Miller, Neil J. Ross
We introduce a framework for providing graphical security proofs for quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more

Low-temperature growth of carbon nanotubes catalyzed by sodium-based ingredients

May 27, 2019
Author(s)
Renu Sharma, Richard Li, Erica F. Antunes, Estekke Cohen, Akira Kudo, Luiz Acauan, Wei-Chang D. Yang, Chih-Ming Wang, Kehang Cui, Andrew Liotta, Ananth G. Rajan, Jules Gardner, David C. Bell, Michael S. Strano, James A. Liddle, Brian L. Wardle
Nanoparticle-catalytic synthesis of carbon nanostructures is an attractive route for producing 1-dimensional carbon nanomaterials, such as carbon nanotubes1 (CNTs), in large enough quantities for their multifunctional capabilities to be applied in

Flood Performance and Dislocation Assessment for Lumberton Homes after Hurricane Matthew

May 26, 2019
Author(s)
Derya Deniz, Elaina Sutley, John W. van de Lindt, Walter G. Peacock, Nathanael Rosenheim, Donghwan Gu, Judith Mitrani-Reiser, Maria Dillard, Maria Koliou, Sara Hamideh
In order to better understand community resilience following a disaster, a multi-disciplinary research team from the Center of Excellence (CoE) for Risk-Based Community Resilience Planning and the National Institute of Standards and Technology (NIST)

Integrative Modeling of Housing Recovery as a Physical, Economic, and Social Process

May 26, 2019
Author(s)
Elaina Sutley, Sara Hamideh, Maria Dillard, Donghwan Gu, Kijin Seong, John W. van de Lindt
This paper presents a set of four simultaneous housing recovery states: RS0 no recovery progress; RS1 repair completion; RS2 re-occupancy; RS3 restored stability; RS4 restored accessibility. The recovery states are aimed at capturing the complex

Accelerated Weathering Parameters for Some Aromatic Engineering Thermoplastics

May 24, 2019
Author(s)
Li Piin Sung, James E. Pickett, Olga Kuvshinnikova, Brett Ermi
Samples of polycarbonate (PC), poly(butylene terephthalate) (PBT), a PC/PBT blend, and poly(styrene-co-acrylonitrile) (SAN), all containing 3 % TiO2 (by mass), were exposed in the NIST (National Institutes of Standards and Technology) SPHERE (Simulated

Carbon Nanotube Thin Film Patch Antennas for Wireless Communications

May 24, 2019
Author(s)
E. A. Bengio, Damir Senic, Lauren W. Taylor, Robert J. Headrick, Michael King, Peiyu Chen, Charles A. Little, John M. Ladbury, Chris Long, Christopher L. Holloway, Aydin Babakhani, James Booth, Nate Orloff
Early work on carbon nanotube (CNT) antennas indicated that their performance could not match that of metals such as copper. However, recent improvements in fluid phase CNT processing have yielded macroscopic CNT materials with better alignment and

pyLLE: a Fast and User Friendly Lugiato-Lefever Equation Solver

May 24, 2019
Author(s)
Gregory T. Moille, Qing Li, Xiyuan Lu, Kartik Srinivasan
The Lugiato-Lefever Equation (LLE), first developed to provide a description of spatial dissipative structures in optical systems, has recently made a significant impact in the integrated photonics community, where it has been adopted to help understand

Root-cause analysis of wear-induced error motion changes of machine tool linear axes

May 23, 2019
Author(s)
Gregory W. Vogl, Jordan Jameson, Andreas Archenti, Karoly Szipka, M A. Donmez
Manufacturers need online methods that give updated information of system capabilities to know and predict the performance of their machine tools. Use of an inertial measurement unit (IMU) is attractive for on-machine condition monitoring, so methods based

The Design and Development of a Tabletop Kibble Balance at NIST

May 23, 2019
Author(s)
Leon S. Chao, Frank C. Seifert, Darine El Haddad, Julian Stirling, David B. Newell, Stephan Schlamminger
On November 16, 2018, the 26th General Conference on Weights and Measures (CGPM) voted unanimously to revise the International System of Units (SI) from a system built on seven base units to one built on seven defining constants and will officially become

Classical polarimetry with a twist: a compact, geometric approach

May 22, 2019
Author(s)
William Sparks, Thomas Germer, Rebecca M. Sparks
We present an approach to classical polarimetry which requires no moving parts, is compact and robust, and which encodes the complete polarization information on a single data frame, accomplished by replacing the rotation of components such as wave plates
