Naturally occurring organobromine compounds (OBCs) including polybrominated dibenzo-p-dioxins in the marine sponge Hyrtios proteus from The Bahamas

August 25, 2021
Author(s)
Qiong Wu, Natalie Eisenhardt, Stephanie Shaw, Joseph Pawlik, John Kucklick, Walter Vetter
Halogenated natural products (HNPs) were identified from organic extracts of the marine sponge Hyrtios proteus from The Bahamas (Caribbean, FAO fishing area 31) using gas chromatography with electron capture negative ion mass spectrometry (GC/ECNI-MS) and

Highly Basic Clusters in the Herpes Simplex Virus 1 Nuclear Egress Complex Drive Membrane Budding by Inducing Lipid Ordering

August 24, 2021
Author(s)
Michael K. Thorsen, Alex Lai, Michelle W. Lee, David Hoogerheide, Gerard C. Wong, Jack H. Freed, Ekaterina Heldwein
During replication of herpesviruses, capsids escape from the nucleus into the cytoplasm by budding at the inner nuclear membrane. This process is mediated by the viral nuclear egress complex (NEC), but how the NEC interacts with lipids or generates

Quantifying Machining Process Inventories In Detailed Design

August 24, 2021
Author(s)
William Z. Bernstein, Till Boettjer, Deverajan Ramanujan
This paper quantifies machining process inventories based on commonly used techniques in various stages of the detailed design process. We investigate variabilities in process inventories between these techniques and their relation to manufacturing process

Synthesis of Mixed-Valent Lanthanide Sulfide Nanoparticles

August 23, 2021
Author(s)
Pricilla Glaser, Orlando Stewart, Rida Atif, Dane Asuigui, Joel Swanson, Adam Biacchi, Angela R. Hight Walker, Gregory Morrison, Hans-Conrad zur Loye, Sarah Stoll
In targeting reduced valence lanthanides, we report the first nanoparticle synthesis of the mixed-valent ferromagnets Eu3S4 and EuSm2S4. Using divalent lanthanide halides with bis(trimethylsilyl)sulfide and oleylamine, we prepared nanoparticles of EuS

Visualizing Model-based Product Definitions in Augmented Reality

August 23, 2021
Author(s)
Teodor Vernica, Robert R. Lipman, William Z. Bernstein
Augmented reality (AR) technologies present immense potential for the design and manufacturing communities. However, coordinating traditional engineering data representations into AR systems without loss of context and information remains a challenge. A

Interplay between Magnetism and Superconductivity in UTe 2

August 22, 2021
Author(s)
Di Wei, David Saykin, Oliver Miller, Sheng Ran, Shanta Saha, Daniel Agterberg, Jorg Schmalian, Nicholas Butch, Johnpierre N. Paglione, Aharon Kapitulnik
Time-reversal symmetry breaking (TRSB) in UTe 2 was inferred from observations of a spontaneous Kerr response in the superconducting state after cooling in zero magnetic field, while a finite c-axis magnetic field training was further used to determine the

First principles study of the quasi one-dimensional organic-inorganic hybrid perovskites (MV)AI3Cl2 (A = Bi, Sb) as promising candidates for ferroelectric photovoltaic and high-density memory applications

August 20, 2021
Author(s)
Chao Wang, Yunlin Lei, Winnie Wong-Ng, Xingxing Wu, Qiang Gu, Wei Zhou, Shouyu Wang, Weifang Liu
Many ferroelectric (FE) organic-inorganic hybrid perovskites (OIHPs) show great promise in the fields of photovoltaic cells and information memory devices. We systematically investigated the FE, optical, and electric properties of quasi-one-dimensional

Motional Squeezing for Trapped Ion Transport and Separation

August 20, 2021
Author(s)
Robert Sutherland, Shaun Burd, Daniel Slichter, Stephen Libby, Dietrich Leibfried
Transport, separation, and merging of trapped ion crystals are essential operations for most large-scale quantum computing architectures. In this Letter, we develop a theoretical framework that describes the dynamics of ions in time-varying potentials with

Ultraviolet Radiation Technologies and Healthcare Associated Infections: Standards and Metrology Needs

August 20, 2021
Author(s)
Dianne L. Poster, C Cameron Miller, Richard Martinello, Norman Horn, Michael T. Postek, Troy Cowan, Yaw S. Obeng, John J. Kasianowicz
The National Institute of Standards and Technology (NIST) hosted an international workshop on ultraviolet-C (UV-C) disinfection technologies on January 14 – 15, 2020 in Gaithersburg, Maryland in collaboration with the International Ultraviolet Association

MAUD Rietveld Refinement Software for Neutron Diffraction Texture Studies of Single and Dual-Phase Materials

August 19, 2021
Author(s)
Alec Saville, Emily Mitchell, Sven Vogel, Adam Abel Creuziger, Jake Benzing, Kester Clarke, Jonah Klemm-Toole, Amy Clarke
This work presents a detailed instructional demonstration using the Rietveld refinement software MAUD for evaluating the crystallographic texture of single- and dual-phase materials, as applied to High-Pressure-Preferred-Orientation (HIPPO) neutron

Mutual control of stochastic switching for two electrically coupled superparamagnetic tunnel junctions

August 19, 2021
Author(s)
Philippe Talatchian, Matthew Daniels, Advait Madhavan, Matthew Pufall, Emilie Jue, William Rippard, Jabez J. McClelland, Mark Stiles
Superparamagnetic tunnel junctions (SMTJs) are promising sources for the randomness required by some compact and energy-efficient computing schemes. Coupling them gives rise to collective behavior that could be useful for cognitive computing. We use a

Weyl-mediated helical magnetism in NdAlSi

August 19, 2021
Author(s)
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya, Baozhu Lu, Guangyong Xu, Yang Zhao, Jose Rodriguez Rivera, Christina M. Hoffman, David E. Graf, Darius H. Torchinsky, Predrag Nikolic, David Vanderbilt, Fazel Tafti, Collin L. Broholm
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect and negative magnetoresistance, all observed in real materials. Whereas these phenomena highlight
