Interface-generated spin currents

September 26, 2018
Author(s)
Vivek P. Amin, Jan Zemen, Mark D. Stiles
Transport calculations based on ab-initio band structures reveal large interface-generated spin currents at Co/Pt, Co/Cu, and Pt/Cu interfaces. These spin currents are driven by in-plane electric fields but flow out-of-plane, and can have similar strengths

Invited Article: Advances in Tunable Laser-based Radiometric Calibration Applications at the National Institute of Standards and Technology, USA

September 26, 2018
Author(s)
John T. Woodward IV, Ping-Shine Shaw, Howard Yoon, Yuqin Zong, Steven W. Brown, Keith R. Lykke
Recent developments at the National Institute of Standards and Technology's facility for Spectral Irradiance and Radiance responsivity Calibrations using Uniform Sources (SIRCUS) are presented. The facility is predicated on the use of broadly tunable

Optical lattice with torus topology

September 26, 2018
Author(s)
Hwanmun Kim, Guanyu Zhu, James V. Porto, Mohammad Hafezi
We propose an experimental scheme to construct an optical lattice where the atoms are confined to the surface of a torus. This construction can be realized with spatially shaped laser beams which could be realized with recently developed high resolution

Reversible Flat to Rippling Phase Transition in Fe Containing Layered Battery Electrode Materials

September 26, 2018
Author(s)
Xi Chen, Sooyeon Hwang, Robin Chisnell, Yichao Wang, Fan Wu, Sooran Kim, Jeffrey W. Lynn, Dong Su, Xin Li
The Jahn-Teller effect in solid-state chemistry relates the symmetry of electronic configuration to the atomic arrangement around the individual transition metal ion. The collective behavior of many such Jahn-Teller active entities is of great interest in

UMP BUILDER: CAPTURING AND EXCHANGING MANUFACTURING MODELS FOR SUSTAINABILITY

September 26, 2018
Author(s)
William Z. Bernstein, Donald E. Libes, David J. Lechevalier
Targeting the improvement of environmental analysis of manufacturing systems, ASTM 3012-16 provides guidelines for formally characterizing manufacturing processes. However, the difficulty that has arisen in the early use of the standard illustrates the

Elaborating the Human Aspect of the NIST Framework for Cyber-Physical Systems

September 25, 2018
Author(s)
Edward R. Griffor, David A. Wollman, Martin J. Burns, Joe Manganelli, Ronald Boring, Stephen Gilbert, Yi-Ching Lee, Dan Nathan-Robers
The National Institute of Standards and Technology (NIST) has developed a Framework for Cyber- Physical Systems (CPS Framework) that supports system engineering analysis, design, development, operation, validation and assurance of CPS. Cyber-physical

Public Safety Communication User Needs: Voices of First Responders

September 25, 2018
Author(s)
Shanee T. Dawkins, Kristen Greene, Michelle P. Steves, Mary F. Theofanos, Yee-Yin Choong, Susanne M. Furman, Sandra S. Prettyman
The public safety community is transitioning from land mobile radios to a communications technology ecosystem including a variety of broadband data sharing platforms. Successful deployment and adoption of new communications technology relies on efficient

Automated Cryptographic Validation (ACV) Testing

September 24, 2018
Author(s)
Apostol T. Vassilev, Larry Feldman, Gregory A. Witte
This bulletin summarizes the NIST Automated Cryptographic Validation (ACV) Testing project. NIST selects and standardizes cryptographic algorithms as NIST-approved for use within the U.S. Federal Government. The Computer Security Division specifies the

Benchmarking for keyword extraction methodologies in maintenance work orders

September 24, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Melinda Hodkiewicz, Thomas Smoker
Maintenance has largely remained a human-knowledge centered activity, with the primary records of maintenance activity being text-based maintenance work orders (MWOs) that attempt to encode the diagnostic processes of technicians. However, the bulk of

Contact and Non-Contact Measurement of Electronic Transport in Individual 2D SnS Colloidal Semiconductor Nanocrystals

September 24, 2018
Author(s)
Adam J. Biacchi, Son T. Le, Brian G. Alberding, Joseph A. Hagmann, Sujitra J. Pookpanratana, Edwin J. Heilweil, Curt A. Richter, Angela R. Hight Walker
Colloidal-based solution syntheses offer a scalable and cost-efficient means of producing 2D nanomaterials in high yield. While much progress has been made towards the controlled and tailorable synthesis of semiconductor nanocrystals in solution, it

Femtosecond Laser Eyewear Protection: Measurements and Precautions for Amplified High Power Applications

September 24, 2018
Author(s)
Christopher J. Stromberg, Sarah Wirick, Maximilian Riedel-Topper, Brian Alberding, Joshua A. Hadler, Edwin J. Heilweil
Ultrafast lasers have become increasingly important as research tools in laboratories and commercial enterprises suggesting laser safety, personal protection and awareness becomes ever more important. Laser safety eyewear are typically rated by their

Harmonization of LC-MS/MS protein assays

September 24, 2018
Author(s)
Alan L. Rockwood, Mark Lowenthal, Cory Bystrom
Harmonization of diagnostic test results is fundamental to the effective use of laboratory testing in the diagnosis, treatment and monitoring of disease. Formal approaches to harmonization and standardization provide a rigorous and high quality Roadmap to

Advanced Maintenance in Manufacturing: Costs and Benefits

September 23, 2018
Author(s)
Douglas Thomas
The costs of maintenance and the potential effect on maintenance costs from adopting predictive maintenance techniques is not well documented at the national level. A number of data items need to be collected to estimate the costs and losses associated

Methodology for evaluating and comparing fluorescence measurement capabilities: Multi-site study of 23 flow cytometers

September 23, 2018
Author(s)
David R. Parks, Wayne A. Moore, Ryan Brinkman, Yong Chen, Danilo Condello, Faysal E. Khettabi, John P. Nolan, Stephen P. Perfetto, Doug Redelman, Josef Spidlen, Jonathan V. Dyke, Lili Wang, James C. Wood
We developed measurement methods and analysis procedures to perform inter-instrument comparisons and used them to evaluate and compare the fluorescence measurement capabilities among 23 cytometers in 9 laboratories selected to provide a range of

MCDC-Star An Open-source MC/DC Measurement Tool

September 22, 2018
Author(s)
Raghu N. Kacker, David R. Kuhn, Eric Wong
Applying MC/DC criterion to real-world projects can be expensive due to not only the cost of commercial tools, but also the difficulty of generating test cases to achieve high coverage. To lower the expense from both aspects, this paper presents an easy-to

Nanoscale Hygromechanical Behavior of Lignin

September 22, 2018
Author(s)
Kristen M. Hess, Jason Killgore, Wil Srubar
The nanoscale hygromechanical behavior of lignin is presented in this work. Three atomic force microscopy experimental methods were used to correlate moisture sorption of lignin to its mechanicalbehavior. First, sorption isotherms were established using
