Current Ecotoxicity Testing Needs Among Selected U.S. Federal Agencies

June 2, 2022
Author(s)
Patricia Ceger, David Allen, Elyssa Arnold, Jennifer Brennan, Lyle Burgoon, Raanan Bloom, Carol Clarke, Natalia Garcia-Reyero, Kellie Fay, Jon Hamm, Paula Henry, Wesley Hunter, Donna Judkins, Nicole Kleinstreuer, Carlie Lalone, James Laurenson, Jessica Leet, Scott Lynn, Teresa Norberg-King, Edward Odenkirchen, Elijah Petersen, Barnett Rattner, Catherine Sprankle, Thomas Steeger, Jim Warren, Sarah Winfield
U.S. regulatory and research agencies utilize ecotoxicity test data to assess the hazards associated with substances that are released into the environment, including consumer products, industrial chemicals, metals and metalloids, nanomaterials, and

Emerging technologies in the field of thermometry

June 2, 2022
Author(s)
Zeeshan Ahmed, Graham Machin, Sergey Dedyulin
The past decade saw the emergence of new temperature sensors that have the potential to disrupt a century-old measurement infrastructure based on resistance thermometry. In this review we present an overview of emerging technologies that are either in the

Measurement-induced quantum phases realized in a trapped-ion quantum computer

June 2, 2022
Author(s)
Michael Gullans, Alexey Gorshkov, David Huse, Christopher Monroe, Crystal Noel, Pradeep Niroula, Daiwei Zhu, Andrew Risinger, Laird Egan, Debopriyo Biswas, Marko Cetina
Many-body open quantum systems balance internal dynamics against decoherence from interactions with an environment. Here, we explore this balance via random quantum circuits implemented on a trapped-ion quantum computer, where the system evolution is

CHESS: The Future Direct Geometry Spectrometer at the Second Target Station

June 1, 2022
Author(s)
G. Sala, M. Mourigal, C. Boone, Nicholas Butch, A. Christianson, O. Delaire, A. J. DeSantis, C. L. Hart, R. Hermann, T. Huegle, D. N. Kent, J. Y. Lin, M. Lumsden, M. Manley, D. G. Quirinale, M. B. Stone, Y. Z.
CHESS is a planned direct geometry neutron chopper spectrometer designed to detect and analyze weak signals intrinsic to small cross-sections (e.g., small mass, small magnetic moments or neutron absorbing materials) in powders, liquids and crystals. CHESS

Fire Resilience of a Steel-Concrete Composite Floor System: Full-Scale Experimental Evaluation for Influence of Slab Reinforcement (Test #2)

June 1, 2022
Author(s)
Lisa Choe, Matthew Hoehler, Matthew Bundy, Rodney A. Bryant, Brian Story, Anthony R. Chakalis, Artur A. Chernovsky, Selvarajah Ramesh, Xu Dai
The National Institute of Standards and Technology is currently conducting a series of large compartment fire tests to investigate the behavior and fire-induced failure mechanisms of the full-scale composite floor assemblies with the two-story steel

Low-GWP Refrigerants: Status and Outlook

June 1, 2022
Author(s)
Piotr Domanski, Samuel Yana Motta
The refrigeration and air-conditioning industry is undergoing a transition to refrigerants having a low global warming potential (GWP). This action is in response to concerns about climate change and national, regional, and international regulations

On-the-Fly Autonomous Control of Neutron Diffraction via Physics-Informed Bayesian Active Learning

June 1, 2022
Author(s)
Austin McDannald, Matthias Frontzek, Andrew Savici, Mathieu Doucet, Efrain Rodriguez, Kate Meuse, Jessica Opsahl-Ong, Daniel Samarov, Ichiro Takeuchi, William Ratcliff, A. Gilad Kusne
We demonstrate the first live, autonomous control over neutron diffraction experiments by developing and deploying ANDiE: the autonomous neutron diffraction explorer. Neutron scattering is a unique and versatile characterization technique for probing the

Phase Field Benchmark Problems for Nucleation

June 1, 2022
Author(s)
Wenkun Wu, David M. Taboada, Jonathan E. Guyer, Peter W. Voorhees, James A. Warren, Daniel Wheeler, Tamas Pusztai, Laszlo Granasy, Olle G. Heinonen
We present nucleation phase field model benchmark problems, expanding on our previous benchmark problems on diffusion, precipitation, dendritic growth, linear elasticity, fluid flow and electrochemistry. Nucleation is the first step in the formation of

Powder X-ray structural analysis and band gap measurements for (CaxSr2-x)MnWO6 (x = 0.25, 0.5, 0.75, 1.5, 1.75).

June 1, 2022
Author(s)
Winnie Wong-Ng, YuQi Yang, Yu-Cheng Lan, GuangYao Liu, Amrit Kafle, Weifang Liu, Jie Hou, Donald Windover, Qingzhen Huang, Sergiy Krylyuk, James A. Kaduk
The structure, powder diffraction patterns and band gap measurements of a series of manganese- and tungsten-containing alkaline-earth double perovskites (CaxSr2-x)MnWO6 (x=0.25, 0.5, 0.75, 1.5, 1.75) have been investigated. Powder X-ray diffraction
