Crystal Structures and Phase Equilibria in the Hafnium-Palladium System

August 1, 2016
Author(s)
Judith K. Stalick, Richard M. Waterstrat
Portions of the Hf-Pd phase diagram have been reinvestigated in an attempt to resolve contradictions that occur between two previous studies. Techniques employed include Rietveld refinement using x-ray and high-temperature neutron diffraction data to

Electrospray Differential Mobility Hyphenated with Single Particle Mass Spectrometry for Characterization of Nanoparticles and their Aggregates

August 1, 2016
Author(s)
Jiaojie Tan, Jingyu Liu, Mingdong M. Li, Hind El Hadri, Vincent A. Hackley, Michael R. Zachariah
The hyphenation of electrospray-differential mobility analysis with single particle-inductively coupled plasma mass spectrometry (ES-DMA-spICP-MS) was demonstrated with the capacity for real- time size, mass and concentration measurement of nanoparticles

Implementing Speed and Separation Monitoring in Collaborative Robot Workcells

August 1, 2016
Author(s)
Jeremy A. Marvel, Richard J. Norcross
We provide an overview and guidance for the speed and separation monitoring methodology as presented in the International Organization of Standardization's technical specification 15066 on collaborative robot safety. Such functionality is provided by

Integrating Top-down and Bottom-up Cybersecurity Guidance using XML

August 1, 2016
Author(s)
Joshua Lubell
This paper describes a markup-based approach for synthesizing disparate information sources, and then discusses a software implementation of the approach. The implementation, developed using XForms and Extensible Stylesheet Language Transformations (XSLT)

Measurement and Modeling of Polarized Specular Neutron Reflectivity in Large Magnetic Fields

August 1, 2016
Author(s)
Brian B. Maranville, Brian J Kirby, Alexander J Grutter, Paul Kienzle, Charles F. Majkrzak, Yaohua Liu, Cindi L. Dennis
The presence of a large applied magnetic field removes the degeneracy of the vacuum energy states for spin-up and spin-down neutrons. For polarized neutron reflectometry, this must be included in the reference potential energy of the Schrodinger equation

New Technologies and Standards Enabling Grid Modernization

August 1, 2016
Author(s)
David A. Wollman, Clark Gellings
“The smart grid, or grid modernization, integrates new interoperable and secure sensing,control, communications, information technologies and power technologies to increase the system efficiency, reliability, resilience, and sustainability of our electric

Results from the Magnetic Suspension Mass Comparator for Vacuum-to-Air Mass Dissemination in Support of the Redefinition of the Kilogram

August 1, 2016
Author(s)
Corey A. Stambaugh, Eric C. Benck, Edward C. Mulhern, Patrick J. Abbott, Zeina J. Kubarych
Experiments to realize the new definition of the kilogram will be carried out in vacuum. NIST has developed a magnetic suspension mass comparator to disseminate the new definition to air. This paper details the current status of the system. This includes

The Canonical Robot Command Language (CRCL)

August 1, 2016
Author(s)
Frederick M. Proctor, Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Craig I. Schlenoff, William P. Shackleford
Industrial robots can perform motion with sub-millimeter repeatability when programmed using the teach-and-playback method. While effective, this method requires significant up-front time, tying up the robot and a person during the teaching phase. Off-line

Transient Optical and Terahertz Spectroscopy of Nanoscale RuO2

August 1, 2016
Author(s)
Edwin J. Heilweil, Brian G. Alberding, Paul D. Cunningham, Joseph S. Melinger, Jeffrey C. Owrutsky, Adam D. Dunkelberger
Solution-deposited nanoscale films of RuO2, “nanoskins,” are effective transparent conductors because after calcining to 523 K they exhibit flat optical extinction across the visible and infrared combined with relatively high electrical conductivity. Upon
