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

A Preliminary Study of RF Propagation for High Data Rate Brain Telemetry

February 11, 2022
Author(s)
Mariella Sarestoniemi, Carlos Pomalaza-Raez, Kamran Sayrafian, Teemu Myllyla, Jari Iinatti
This paper presents the preliminary results of a study on the radio frequency (RF) propagation inside the human skull at several Industrial, Scientific and Medical (ISM) and ultrawideband UWB frequencies. These frequency bands are considered as possible

Synthesis, crystal structure, and physical properties of BaSnS2

February 11, 2022
Author(s)
Wilarachchige Gunatilleke, Andrew May, Angela R. Hight Walker, Adam Biacchi, George Nolas
Phase-pure BaSnS2, with space group Pn21/c, was synthesized and the structural and physical properties were investigated. The thermal properties and optical measurements are reported for the first time. The Debye temperature and Sommerfeld coefficient were

Christina Cecelski, Kimberly Harris, Cassie Goodman, William A. Kimes, Philip Liu, Walter R. Miller Jr., Jennifer Carney
The Gas Sensing Metrology Group at NIST provides accurate, stable gaseous standards for use in various types of emissions testing and environmental monitoring. The group develops and maintains the highest level of primary gas standards, which provide

Empirical Differences in LTE Open- and Closed-Loop Power Control

February 10, 2022
Author(s)
Azizollah Kord
We present the empirical Physical Uplink Shared Channel radiated power of a User Equipment in a commercial Long-Term Evolution Frequency-Division Duplex system in open- and closed-Loop power control. We present new insights, targeted on power control, from

Empirical Differences in LTE Open- and Closed-Loop power Control

February 10, 2022
Author(s)
Azizollah Kord, Jason Coder, Aric Sanders
We present the empirical Physical Uplink Shared Channel (PUSCH) radiated power of a User Equipment (UE) in a commercial Long-Term Evolution (LTE) frequency division duplex system. We measured the radiated PUSCH channel power while varying 28 different

Performance of NIST SRM(R) 2917 with 13 Recreational Water Quality Monitoring qPCR Assays

February 10, 2022
Author(s)
Jessica Willis, Mano Sivaganesan, Richard Haugland, Jason Kralj, Stephanie Servetas, Monique Hunter, Scott Jackson, Orin Shanks
Fecal pollution remains a significant challenge for recreational water quality management worldwide. In response, there is a growing interest in the use of real-time quantitative PCR (qPCR) methods to achieve same-day notification of recreational water
