Structural and Magnetic Properties of Electrodeposited Co/Cu Multilayers

March 1, 1999
Author(s)
M Shima, L Salamanca-Riba, Thomas P. Moffat, Robert D. McMichael
A series of [Co(x ML)/Cu(17 ML)]100 multilayers were electrodeposited on Si(0 0 1) substrates covered with Cu seed layers. Magnetic hysteresis loops for lms with x 2 ML have sigmoidal shapes and the temperature dependence indicates a superparamagnetic

Least-Squares Fitting Algorithms of the NIST Algorithm Testing System

December 1, 1998
Author(s)
Craig M. Shakarji
This report describes algorithms for fitting certain curves and surfaces to points in three dimensions. All fits are based on orthogonal distance regression. The algorithms were developed as reference software for the NIST Algorithm Testing System, which

Post-Installed Anchors. A Literature Review

January 1, 1998
Author(s)
Geraldine S. Cheok, Long T. Phan
A literature review of studies on the behavior of post-installed concrete anchors is presented. The survey covers several types of anchors that are subjected to tension loads, shear loads, and to combined shear and tension loads. Brief summaries of the

Systems Integration for Manufacturing Applications Technical Program Plan

August 1, 1997
Author(s)
James E. Fowler
The Systems Integration for Manufacturing Applications (SIMA) Program is NIST''s coordinating focus for manufacturing efforts sponsored under the U.S. government''s High Performance Computing and Communications intitiative. Initiated in 1994, the SIMA

Nanofabrication of a Two-Dimensional Array Using Laser-Focused Atomic Deposition

September 4, 1995
Author(s)
R Gupta, Jabez J. McClelland, Zeina J. Kubarych, Robert Celotta
Fabrication of a two-dimensional array of nanometer-scale chromium features on a silicon substrate by laser-focused atomic deposition is described. Features 13plus or minus}1 nm high and having a full-width at half maximum of 80plus or minus}10 nm are

JARVIS-Leaderboard: A Large Scale Benchmark of Materials Design Methods

May 7, 2024
Author(s)
Kamal Choudhary, Daniel Wines, Kevin Garrity, aldo romero, Jaron Krogel, Kayahan Saritas, Panchapakesan Ganesh, Paul Kent, Pascal Friederich, Vishu Gupta, Ankit Agrawal, Pratyush Tiwary, ichiro takeuchi, Robert Wexler, Arun Kumar Mannodi-Kanakkithodi, Avanish Mishra, Kangming Li, Adam Biacchi, Francesca Tavazza, Ben Blaiszik, Jason Hattrick-Simpers, Maureen E. Williams
Reproducibility and validation are major hurdles for scientific development across many fields. Materials science in particular encompasses a variety of experimental and theoretical approaches that require careful benchmarking. Leaderboard efforts have

Reduced-Scale Test to Assess the Effect of Fire Barriers on the Flaming Combustion of Cored Composites: an Upholstery-Material Case Study

September 4, 2020
Author(s)
Mauro Zammarano, John R. Shields, Isaac T. Leventon, Ickchan Kim, Shonali Nazare, Andre L. Thompson, Rick D. Davis, Artur A. Chernovsky, Matthew F. Bundy
In this work, we describe a reduced-scale test (“Cube” test), based on cone calorimetry, measuring the fire performance (heat release rate, propensity to pool-fire formation, etc.) of composite specimens including a fire barrier (FB) and a flammable core

Electromagnetic Metrology on Concrete and Corrosion

June 1, 2011
Author(s)
Sung Kim, Jack T. Surek, James R. Baker-Jarvis
To go beyond current electromagnetic nondestructive evaluation (NDE) methods for reinforcing bar (rebar) corrosion we are exploring unique magnetic or electric spectral features and whether these might be prominent enough at the concrete cover depth to

Optical Control and Management Security Standards for the GIG-BE

October 31, 2004
Author(s)
Renee Esposito, Sheila E. Frankel, Richard Graveman, Scott McNown
This paper presents an overview of requirements and standards development activities for securing the control and management infrastructure protocols for optical networking protocols used in the Global Information Grid-Bandwidth Expansion (GIG-BE). Our

Milliwatt-threshold visible-telecom optical parametric oscillation using silicon nanophotonics

December 20, 2019
Author(s)
Xiyuan Lu, Gregory Moille, Anshuman Singh, Qing Li, Daron Westly, Ashutosh Rao, Su P. Yu, Travis Briles, Scott Papp, Kartik Srinivasan
The on-chip creation of coherent light at visible wavelengths is of interest to many applications in spectroscopy, sensing, and metrology. Towards that goal, here we propose and demonstrate the first on-chip visible-telecom optical parameteric oscillator
