Structural Origin of Recovered Ferroelectricity in BaTiO3 Nanoparticles

August 24, 2023
Author(s)
Bruce D. Ravel, Trevor Tyson, Han Zhang, Sizhan Liu, SANJIT GHOSE, U.J. Idehenre, Yury Barnakov, S.A. Basun, D.R. Evans
Nanoscale BaTiO3 particles (10 nm) prepared by ball-milling a mixture of oleic acid and heptane have been reported to have an electric polarization several times larger than that for bulk BaTiO3. In this work, detailed local, intermediate, and long-range

Broadband Electromagnetic Properties of Engineered Flexible Absorber Materials

August 23, 2023
Author(s)
Luckshitha Suriyasena Liyanage, Connor Smith, Jacob Pawlik, Sarah Evans, Angela Stelson, Chris Long, Nate Orloff, David Arnold, Jim Booth
Flexible and stretchable materials have attracted significant interest for applications in wearable electronics and bioengineering fields. Recent developments also incorporate embedded microwave circuits, components, and systems with engineered flexible

Inferring the nominal molecular mass of an analyte from its electron ionization mass spectrum

August 23, 2023
Author(s)
Arun Moorthy, Anthony J. Kearsley, William Mallard, William E. Wallace, Stephen E. Stein
The performance of three algorithms for predicting nominal molecular mass from an analyte's electron ionization mass spectrum is presented. The Peak Interpretation Method (PIM) attempts to quantify the likelihood that a molecular ion peak is contained in

National Institute of Standards and Technology Environmental Scan 2023: Societal and Technology Landscape to Inform Science and Technology Research

August 23, 2023
Author(s)
Ashley Boggs-Russell, Kerrianne Buchanan, David W. Griffith, Heather Evans, Dimitrios Meritis, Lisa Ng, Anna Sberegaeva, Michelle Stephens
The 2023 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through three separate lenses

Phishing for User Context: Understanding the NIST Phish Scale

August 23, 2023
Author(s)
Shanee Dawkins, Jody Jacobs
The NIST Phish Scale is a method for measuring human phishing detection difficulty, providing a metric – a phishing email detection difficulty rating – for phishing training implementers to gain a better understanding of the variability in click rates

The complete sequence of a human Y chromosome

August 23, 2023
Author(s)
Arang Rhie, Sergey Nurk, Monika Cechova, Savannah Hoyt, Dylan Taylor, Nathanael David Olson, Justin Zook, Adam Phillippy
The human Y chromosome has been notoriously difficult to sequence and assemble because of its complex repeat structure that includes long palindromes, tandem repeats and segmental duplications1,2,3. As a result, more than half of the Y chromosome is

An Evolving Regulatory Landscape for Commercial Electric Vehicle Fueling

August 22, 2023
Author(s)
Tina G. Butcher, Michael Nelson
Plug-in electric vehicles (PEV), which include "all-electric" battery EV (BEV) and plug-in hybrid EV (PHEV), comprise a rapidly growing proportion of the U.S. automobile market – nearly 8% of all light-duty vehicles sold in Oct. 2022, a 41.4% rise over

Effects of mechanical deformation on dislocation density and phase partitioning in 4130 steel

August 22, 2023
Author(s)
Zack Buck, Matthew Connolly, May Ling Martin, Damian Lauria, Jason Killgore, Peter Bradley, Yan Chen, Ke An, Andrew Slifka
Interrupted tensile tests were performed on an AISI 4130 pressure vessel steel and investigated by neutron diffraction and scanning microscopy techniques. Analysis of the neutron diffraction patterns reveal a partitioning of ferrite and martensite phases

Lower-GWP Non-Flammable Refrigerant Blends to Replace HFC-134a

August 21, 2023
Author(s)
Harrison M. Skye, Piotr A. Domanski, Mark O. McLinden, Valeri I. Babushok, Ian Bell, Tara Fortin, Michael Hegetschweiler, Marcia L. Huber, Mark A. Kedzierski, Dennis Kim, Lingnan Lin, Gregory T. Linteris, Stephanie L. Outcalt, Vance (Wm.) Payne, Richard A. Perkins, Aaron Rowane
Non-flammable, lower global-warming-potential (GWP) refrigerants are needed to replace HFC-134a (GWP=1300) in military equipment. We previously used thermodynamic cycle simulations to screen 100 000+ refrigerant blends and identified 23 candidate

Mid-Infrared, Near-Infrared, and Visible Nanospectroscopy of Hydrogen-Intercalated MoO3

August 21, 2023
Author(s)
Jeffrey Schwartz, Sergiy Krylyuk, Devon Jakob, Albert Davydov, Andrea Centrone
Control over the local chemical composition and spatial heterogeneities in nanomaterials provides a means to impart new functions and to tailor their properties in many applications. For two-dimensional (2D) van der Waals materials, intercalation is one

RECENT DEVELOPMENTS IN ONTOLOGY STANDARDS AND THEIR APPLICABILITY TO BIOMANUFACTURING

August 21, 2023
Author(s)
Milos Drobnjakovic, Boonserm Kulvatunyou, Vijay Srinivasan, Simon P. Frechette
ISO and IEC have jointly initiated, and recently issued, a series of standards (the ISO/IEC 21838 series) for top-level ontologies. These standards have been used by industrial consortia to develop and disseminate standards for mid-level ontologies to ease

Skyrmion-Excited Spin-Wave Fractal Networks

August 18, 2023
Author(s)
Nan Tang, W. L. N. C. Liyanage, Sergio A. Montoya, Sheena Patel, Lizabeth J. Quigley, Alexander Grutter, Michael R. Fitzsimmons, Sunil Sinha, Julie A. Borchers, Eric E. Fullerton, Lisa Debeer-Schmitt, Dustin A. Gilbert
Magnetic skyrmions exhibit unique, technologically relevant pseudo-particle behaviors which arise from their topological protection, including well-defined, three-dimensional breathing and gyration modes which occur at microwave frequencies. During dynamic
