Properties for Accurate Gas Flow Measurements

October 15, 2010
Author(s)
John D. Wright
… 2009, NIST’s calibration data were reduced using REFPROP 7.0. Flowmeter users who recalibrate their meters at NIST and … reduced the uncertainty of air flow calibrations from 0.05 % to 0.025 %. NIST now reduces calibration data for … flow venturi calibrations performed in N2 and air from > 0.05 % to …

High Temperature Lead-free Solder for Microelectronics

June 1, 2001

Frank W. Gayle, G Becka, J Badgett, G Whitten, TG Y. Pan, A Grusd, B B. Bauer, R Lathrop, J Slattery, I Anderson, J Foley, D Napp, J D. Mather, C Olson
… and a full manufacturability and fatigue testing of the 7 most promising of those alloys, namely Sn-3.5Ag, …

Reference Material 8376 Microbial Pathogen DNA Standards for Detection and Identification

June 1, 2022
Author(s)
Jason Kralj, Dieter Tourlousse, Monique Hunter, Erica Romsos, Blaza Toman, Peter Vallone, Scott Jackson
Reference Material (RM) 8376 is intended for NGS-based measurements quantitative to the chromosome. A unit of RM 8376 consists of 20 components (A-T, 19 bacteria and 1 human) each containing well-characterized DNA in 10 mmol/L Tris-HCl, 1 mmol/L EDTA pH 8

High accuracy CO2 line intensities determined from theory and experiment

June 15, 2015
Author(s)
Joseph T. Hodges, Oleg L. Polyansky, Katarzyna E. Bielska, Melanie C. Ghysels, Lorenzo Lodi, N Zobov, Jonathan Tennyson
The atmospheric concentration of carbon dioxide (CO2), with its consequences for the greenhouse effect and climate change, is being closely monitored by a variety of space-borne and ground-based remote sensing experiments. These experiments require a

Two-photon interference with continuous-wave operating multi-mode coherent light

September 12, 2013
Author(s)
Yong-Su Kim, Oliver T. Slattery, Paulina Kuo, Xiao Tang
We report two-photon interference with continuous-wave multi-mode coherent light. We show that the two-photon interference, in terms of the detection time difference, reveals two-photon beating fringes with the visibility V = 0.5. While scanning the

Design of remnant magnetization FeCoV films as compact, heatless neutron spin rotators

April 5, 2013
Author(s)
Michael G. Huber, M. O. Abutaleb, Dimitry A. Pushin, Charles F. Majkrzak, Muhammad Arif, D G. Cory
We introduce a design of a neutron spin rotator for applications with space and temperature constraints. These passive devices employ remnant magnetization Fe- CoV thin films and can be tuned experimentally to achieve arbitrary rotation of an incident

Compressed-Liquid Density Measurements of Methyl Oleate and Methyl Linoleate

September 30, 2011
Author(s)
Stephanie L. Outcalt
Compressed liquid densities of the fatty acid methyl esters methyl linoleate and methyl oleate have been measured with a vibrating-tube densimeter. The temperature and pressure range of the measured data is from 270 K to 470 K, and 0.5 MPa to 50 MPa. The

Characterization of Soluble Anthradithiophene Derivatives

March 18, 2010
Author(s)
Brad Conrad, Calvin Chan, Marsha A. Loth, John E. Anthony, David J. Gundlach
… grown and device hole mobility is shown to exceed 0.05 cm$^{2}$/Vs with on/off ratios of 10$^{7}$. F- TBDMS ADT is also observed to be readily soluble with …

Low-Cost, Broadband Absorber Measurements

October 1, 2000
Author(s)
David R. Novotny, Robert T. Johnk, Arthur Ondrejka
We present a method for evaluating broadband absorber in a non-ideal testing environment. Using broadband, short impulse TEM horns, a frequency-rich spectrum (equivalent pulse length 0.5 ns) illuminates a sample of material under test and the reflections

Hyperthermal (1-10 eV) cobalt deposition on Si(100)

August 1, 1996
Author(s)
M P. Knowles, S R. Leone
Cobalt atoms with enhanced kinetic energy (0-10 eV) are deposited on room temperature Si(100) and compared to thermal cobalt deposition. Growth is monitored with Auger electron spectroscopy (AES) and low energy electron diffraction (LEED). At low coverages

Understanding Signatures of Emergent Magnetism in Topological Insulator/Ferrite Bilayers

March 24, 2022
Author(s)
Lauren J. Riddiford, Alexander Grutter, Timothy Pillsbury, Max Stanley, Danielle Reifsnyder Hickey, Peng Li, Nasim Alem, Nitin Samarth, Yuri Suzuki
Magnetic insulator and topological insulator heterostructures have been studied in search of induced magnetism in the topological insulator, but chiral edge states have been elusive. We have identified MgAl 0.5Fe 1.5O 4/Bi 2Se 3 bilayers for a possible

Solution Structure of Zinc-Seamed C-alkylpyrogallol[4]arene Dimeric Nanocapsules

January 15, 2021
Author(s)
Harshita Kumari, Wei G. Wycoff, Collin M. Mayhan, Steven R. Kline, Joshua R. So, Carol A. Deakyne, John E. Adams, Jerry L. Atwood
The structural stability and solution geometry of zinc-seamed C-propylpyrogallol[4]arene dimers with ligands has been studied in solution using in situ neutron scattering and 2D-DOSY NMR 15 methods. In comparison with the structures of the analogous copper

A ROUND ROBIN EXPERIMENT TO SUPPORT BOND VOID MEASUREMENT STANDARDS

May 1, 2016
Author(s)
Richard A. Allen, David T. Read, Victor H. Vartanian, Winthrop A. Baylies, William Kerr, Mark Plemmons, Kevin T. Turner
A round robin experiment to compare the sensitivities of various metrology tools to small voids between bonded wafers such as are used in three-dimensional stacked integrated circuits (3DS-ICs) and MEMS packaging. Participants received a set of four bonded
