Neutron vibrational spectroscopic evidence for short H???H contacts in the RNiInH1.4; 1.6 (R = Ce, La) metal hydride

February 1, 2022
Author(s)
Ryan Klein, Rafael Balderas-Xicohtencatl, Jan Petter Maehlen, Terrence J. Udovic, Craig Brown, Robert Delaplane, Yongqiang Cheng, Roman Denys, Anibal Ramirez Cuesta, Volodymyr Yartys
Intermetallic metal hydrides are critical materials for hydrogen storage applications, however, metal hydrides with greater storage capacities are still needed. Within metal hydrides, the volumetric storage capacities are limited by the number of hydrogen

The National Institute of Standards and Technology's Impact on Fire Safety Standards

February 1, 2022
Author(s)
Benjamin M. Miller, Tom Latourrette, Drake Warren, David Metz
Standards provide critical benefits across a wide variety of contexts, including safety and health, environmental protection, and quality of products and services. However, while these benefits are generally acknowledged, estimating the social and economic

High-Gain 500-GHz InP HBT Power Amplifiers

January 31, 2022
Author(s)
Jerome Cheron, Rob Jones, Richard Chamberlin, Dylan Williams, Miguel Urteaga, Kassi Smith, Nick Jungwirth, Bryan Bosworth, Chris Long, Nate Orloff, Peter Aaen, Ari Feldman
We report two terahertz monolithic integrated circuit (TMIC) amplifiers operating at 500 GHz. The 6-stage single-ended power amplifiers use Teledyne's 130 nm indium-phosphide double heterojunction bipolar transistors in a common-base configuration. The

Optofluidic Flow Meter for sub-nanoliter per minute flow measurements

January 31, 2022
Author(s)
Jalal Sadeghi, Paul Patrone, Anthony J. Kearsley, Gregory A. Cooksey
Performance improvements in microfluidic systems depend on accurate measurement and control of fluids on the micro- and nanoscale, and new applications are continuously moving the needle to lower volumetric flow rates. This work focuses on improving an

Bioinspired Wear-Resistant and Ultra-Durable Functional Gradient Coatings

January 28, 2022
Author(s)
Zhengzhi Wang, Kun Wang, Houbing Huang, Xiao Cui, Zuoqi Zhang, Martin Chiang
For mechanically protective coatings, the coating material usually requires sufficient stiffness and strength to resist external forces and meanwhile matched mechanical properties with the underneath substrate to maintain the structural integrity. These

Micromechanical Compatibility Between Cells and Scaffolds Directs Phenotypic Transition of Stem Cells

January 28, 2022
Author(s)
Yang Song, Jiaoyue Long, Jeremiah Woodcock, Joy Dunkers, Hung Chun Lin, Douglas M. Fox, Xiaoling Liao, Yonggang Lv, Li Yang, Martin Chiang
This study experimentally substantiates the micromechanical compatibility between cell and substrate is essential for cells to achieve energetically favorable mechanotransduction that directs phenotypic transitions. The argument for this compatibility is

Styrene-Maleic Acid Copolymer Nanodiscs to Determine the Shape of Membrane Proteins

January 28, 2022
Author(s)
Cheol Jeong, Ryan Franklin, Karen J. Edler, Kenno Vanommeslaeghe, Joseph E. Curtis
Lipid nanodiscs can be used to solubilize functional membrane proteins (MPs) in nativelike environments. Thus, they are promising reagents that have been proven useful to characterize MPs. Both protein and non-protein molecular belts have shown promise to

Brominated nanoscale diamond enables room temperature and catalysis free functionalization chemistry

January 27, 2022
Author(s)
Cynthia Melendrez, Jorge Lopez-Rosas, Tsz Cheung, Camron Stokes, Sang-Jun Lee, Jan Vavra, Helena Raabova, Vaclav Vanek, Sami Sainio, Dennis Nordlund, W.Bertrand (Randy) Doriese, Galen O'Neil, Daniel Swetz, Joel Ullom, Kent Irwin, Peter Cigler, Polo Tran, Halim Muhammad, Virginia Altoe, Charles Titus, Jocelyn Valenzuela, Grace Jeanpierre, Abraham Wolcott
Bromination of diamond surfaces has not been explored and can potentially open new avenues for increased chemical reactivity. Aerobically oxidized high-pressure high-temperature nanoscale diamond (ND) is a widely used host for the nitrogen vacancy centers

New reference materials for trace-levels of actinide elements in plutonium

January 27, 2022
Author(s)
Richard Essex, Lav Tandon, Amy Gaffney, Cole Hexel, Debbie Bostick, Lisa Colletti, Diana Decker, Casey Finstad, Joseph Giaquinito, Elmer Lujan, John Partridge, Benjamin Roach, John Rolinson, Kyle Samperton, Alice Slemmons, Khalil Spencer, Floyd Stanley, Lisa Townsend, Kerri Treinen, Ross Williams, Christopher Worley
Two plutonium oxides were prepared as unique reference materials for actinides occurring as trace constituents in Pu. Each reference material unit is approximately 200 mg of PuO2 in a quartz glass vial. Characterized attributes of the oxides included mass
