Demonstration of a laser powder bed fusion combinatorial sample for high-throughput microstructure and indentation characterization

August 3, 2021
Author(s)
Jordan Weaver, Adam L. Pintar, Carlos R. Beauchamp, Howard Joress, Kil-Won Moon, Thien Q. Phan
High-throughput experiments that use combinatorial samples with rapid measurements can be used to provide process-structure-property information at reduced time, cost, and effort. Developing these tools and methods is essential in additive manufacturing

Exploring Government Security Awareness Programs: A Mixed-Methods Approach

August 3, 2021
Author(s)
Jody Jacobs, Julie Haney, Susanne M. Furman, Fernando Barrientos
Organizational security awareness programs are often underfunded and rely on part-time security awareness professionals who may lack sufficient background, skills, or resources necessary to manage an effective and engaging program. U.S. government

Evolution of Magnetic Interactions in Sb-Substituted MnBi 2 Te 4

August 2, 2021
Author(s)
S. Riberolles, Q. Zhang, Elijah Gordon, Nicholas Butch, Liqin Ke, J.-Q. Yan, R. McQueeney
The Mn(Bi 1−xSb x) 2Te 4 series is purported to span from antiferromagnetic (AF) topological insulator at x = 0 to a trivial AF insulator at x = 1. Here we report on neutron diffraction and inelastic neutron scattering studies of the magnetic interactions

A Novel Data Standards Platform using ISO Core Components Technical Specification

August 1, 2021
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Elena Jelisic, Hakju Oh, Simon P. Frechette, Vijay Srinivasan
It is generally observed in inter-organizational communication that present-day data exchange standards are too costly and too complex to develop and use. These problems in data exchange are felt keenly by manufacturing industry with its vast supply chains

Design of a 3000 pixel transition-edge sensor x-ray spectrometer for microcircuit tomography

August 1, 2021
Author(s)
Paul Szypryt, Douglas Bennett, William J. Boone, Amber L. Dagel, G Dalton, William Doriese, Malcolm Durkin, Joseph Fowler, Edward Garboczi, Jonathon D. Gard, Gene Hilton, Jozsef Imrek, E S. Jimenez, Vincent Y. Kotsubo, K Larson, Zachary H. Levine, John Mates, D McArthur, Kelsey Morgan, Nathan J. Nakamura, Galen O'Neil, Nathan Ortiz, Christine G. Pappas, Carl Reintsema, Dan Schmidt, Daniel Swetz, K R. Thompson, Joel Ullom, C Walker, Joel C. Weber, Abigail Wessels, J W. Wheeler
Feature sizes in integrated circuits have decreased substantially over time, and it has become increasingly difficult to three-dimensionally image these complex circuits after fabrication. This can be important for process development, defect analysis, and

Adaptive Peak Fitting for Isotope Analysis via Atom Probe Mass Spectrometry

July 30, 2021
Author(s)
Frederick Meisenkothen, Daniel Samarov, Mark McLean, Irina Kalish, Eric B. Steel
Atom probe tomography (APT) is an emergent characterization technique that has begun to see widespread use within the last 15 years. The technique offers the highest spatial resolution of any mass spectrometry technique for solid-state specimens, as well

Representing and Comparing Site-Specific Glycan Abundance Distributions of Glycoproteins

July 30, 2021
Author(s)
Concepcion Remoroza, Meghan Burke Harris, Yi Liu, Yuri Mirokhin, Dmitrii V. Tchekhovskoi, Xiaoyu (Sara) Yang, Stephen E. Stein
A method for representing and comparing distributions of N-linked glycans located at specific sites in proteins is presented. The representation takes the form of a simple mass spectrum for a given peptide sequence, with each peak corresponding to a

Spin Reorientation in Antiferromagnetic Layered FePt5P

July 30, 2021
Author(s)
Xin Gui, Madalynn Marshall, Ranuri Dissanayaka Mudiyanselage, Ryan Klein, Qiang Chen, Qiang Zhang, William Shelton, Haidong Zhou, Craig Brown, Huibo Cao, Martha Greenblatt, Weiwei Xie
FePt5P, a new substitutional variant of the CeCoIn5 structure type in space group P4/mmm, was synthesized by high-temperature solid-state method and structurally characterized by X-ray diffraction. FePt5P contains layers of FePt12 clusters formed by

Thermal Boundary Layers in Critical Flow Venturis

July 30, 2021
Author(s)
John D. Wright, Aaron Johnson, Michael R. Moldover, Woong Kang, Liang Zhang, Bodo Mickan
We improve the usefulness of small (diameter 10 mm) critical flow venturis (CFVs) as transfer standards for gas flow by measuring and explaining how their discharge coefficients depend on the temperature T of their environment. At Reynolds numbers Re 2.5

Dataset construction challenges for digital forensics

July 29, 2021
Author(s)
James R. Lyle, Graeme Horsman
As the digital forensic field develops, taking steps towards ensuring a level of reliability in the processes implemented by its practitioners, emphasis on the need for effective testing has increased. In order to test, test datasets are required, but

Impact ionization-induced bistability in CMOS transistors at cryogenic temperatures for capacitorless memory applications

July 29, 2021
Author(s)
Alexander Zaslavsky, Curt A. Richter, Pragya Shrestha, Brian Hoskins, Son Le, Advait Madhavan, Jabez J. McClelland
Cryogenic operation of complementary metal oxide semiconductor (CMOS) silicon transistors is crucial for quantum information science, but it brings deviations from standard transistor operation. Here we report on sharp current jumps and stable hysteretic
