Temporal tends of persistent organic pollutants in Sarasota Bay common bottlenose dolphins (Tursiops truncatus)

February 17, 2022
Author(s)
John Kucklick, Ashley Boggs-Russell, Kevin Huncik, Amanda Moors, Elizabeth Davis, Gina Ylitalo, Mary McConnell, Christina Makris, Randall Wells
Legacy persistent organic pollutants (POPs) were measured in blubber samples collected from 196 common bottlenose dolphins (Tursiops truncatus) during 2000 to 2016 in the Sarasota Bay, Florida, ecosystem. Legacy POPs included polychlorinated biphenyl

Heterosubstrate Illumination Effects in III-V Solar Cells

February 16, 2022
Author(s)
Brianna Conrad, Behrang Hamadani
Reference cell-based current versus voltage ( I–V ) measurements assume that the effect of an illumination spectrum on a solar cell's performance can be fully captured by the multiplication of the spectrum with the device's spectral response and subsequent

Nuclear Data to Reduce Uncertainties in Reactor Antineutrino Measurements

February 16, 2022
Author(s)
Hans Pieter Mumm, Catherine Romano, Nathaniel Bowden, Andrew Conant, Bethany Goldblum, Patrick Huber, Jonathan Link, Bryce Littlejohn, Juan Pedro Ochoa-Ricoux, Shikha Prasad, Catherine Riddle, Alejandro Sonzogni, William Wieselquist
The large quantities of antineutrinos produced through the decay of fission fragments in nuclear reactors provide an opportunity to study the properties of these particles and to investigate their use in reactor monitoring. The reactor antineutrino spectra

Physics in the Machine: Integrating Physical Knowledge in Autonomous Phase-Mapping

February 16, 2022
Author(s)
A. Gilad Kusne, Austin McDannald, Brian DeCost
Application of artificial intelligence (AI), and more specifically machine learning, to the physical sciences has expanded significantly over the past decades. In particular, science-informed AI, also known as scientific AI or inductive bias AI, has grown

Silicone tube humidity generator

February 16, 2022
Author(s)
Robert F. Berg, Nicola Chiodo, Eric Georgin
We describe the model and construction of a two-flow (or divided-flow) humidity generator, developed at LNE-CNAM, that uses mass flow controllers to mix a stream of dry gas with a stream of humid gas saturated at 28 °C. It can generate a wide range of

Simulation of Residential CO Exposures from Portable Generators with and without CO Hazard Mitigation Systems Meeting Requirements of Voluntary

February 16, 2022
Author(s)
Steven Emmerich, Brian Polidoro, Matthew Hnatov, Janet Buyer, Matthew Brookman
This report documents work performed by the U.S. National Institute of Standards and Technology (NIST) and the U.S. Consumer Product Safety Commission (CPSC) under an interagency agreement in support of the Commission's effort to address the carbon

Analyzing 5G NR-U and WiGig Coexistence with Multiple-Beam Directional LBT

February 15, 2022
Author(s)
Yao Ma, Susanna Mosleh, Jason Coder
The mmWave radio frequency (RF) spectrum allocations provide a large bandwidth and an excellent dynamic spectrum sharing (DSS) opportunity for emerging 5G New-Radio unlicensed (NR-U) and Wireless Gigabit (WiGig) services. To support constructive DSS, we

Feasibility study of quantum computing using trapped electrons

February 15, 2022
Author(s)
Qian Yu, Alberto Alonso, Jackie Caminiti, Robert Sutherland, Dietrich Leibfried, Kayla Rodriguez, Madhav Dhital, Boerge Hemmerling, Hartmut Haeffner, Kristin Beck
We investigate the feasibility of using electrons in a linear Paul trap as qubits in a future quantum computer. We discuss the necessary experimental steps to realize such a device through a concrete design proposal, including trapping, cooling, electronic

Probing the non-classical dihydrogen ligand in OsClH3(PPh3)3 using X-ray and neutron diffraction, inelastic neutron scattering, and theoretical calculations

February 15, 2022
Author(s)
Carly Carter, Ryan Klein, Wei Zhou, Terrence J. Udovic, Craig Brown, Ting-Bin Wen, Thomas Cundari, Muhammed Yousufuddin
: Dihydrogen ligation to metal centers results in a wide range of metal-hydrogen interactions. Compounds containing non-classical dihydrogen ligands in which the H–H contacts are significantly longer than the 0.74 Å distance found in solid H2 are

Spatially-resolved bandgap and dielectric function in two-dimensional materials from Electron Energy Loss Spectroscopy

February 15, 2022
Author(s)
Abel Brokkelkamp, Jaco ter Hoeve, Isabel Postmes, Sabrya van Heijst, Luigi Maduro, Albert Davydov, Sergiy Krylyuk, Juan Rojo, Sonia Conesa Boj
The electronic properties of two-dimensional (2D) materials depend sensitively on the underlying atomic arrangement down to the monolayer level. Here we present a novel strategy for the determination of the band gap and complex dielectric function in 2D

Wireless Time Sensitive Networking Impact on an Industrial Collaborative Robotic Workcell

February 15, 2022
Author(s)
Susruth Sudhakaran, Karl Montgomery, Mohamed Hany, Dave Cavalcanti, Rick Candell
In this paper, we describe a collaborative robotic workcell testbed enabled by Wireless Time Sensitive Networking (WTSN) technologies and discuss deployment, performance measurement and management guidelines challenges. We detail the methodologies for

Refocusing the Barriers to Sustainability for Small and Medium Manufacturers

February 14, 2022
Author(s)
Xavier R. Escoto, Demsas Gebrehewot, KC Morris
Sustainable manufacturing practices are a necessary component of sustainable development. Current practices in a linear economy—produce, consume, discard—will not be sufficient to sustain humanity over the long term. At the same time manufacturing is

A method to quantify composition, purity, and cross-link density of the polyamide active layer in reverse osmosis composite membranes using 13C cross-polarization magic angle spinning nuclear magnetic resonance spectroscopy

February 12, 2022
Author(s)
Ryan Nieuwendaal, Christopher Stafford, Jeff Wilbur
A method for harvesting and purifying the thin polyamide (PA) active layer from thin-film composite (TFC) reverse osmosis (RO) membranes was developed, enabling quantitative nuclear magnetic resonance (NMR) measurements of the composition and cross-linking
