Magnetic structure of magnetoelectric multiferroic HoFeWO6

February 1, 2022
Author(s)
C. Dhital, Rebecca Dally, D. Pham, T. Keen, Qiang Zhang, P. Siwakoti, R. Nepal, R. Jin, R. Rai
The polar magnetic oxide, HoFeWO6, is synthesized, and its crystal structure, magnetic structure, and thermodynamic properties are investigated. HoFeWO6 forms the polar crystal structure (space group Pna21 (#33)) due to the cation ordering of W6+ and Fe3+

Measurement sensitivity of DUV scatterfield microscopy parameterized with partial coherence for duty ratio-varied periodic nanofeatures

February 1, 2022
Author(s)
Taekyung Kim, Eikhyun Cho, Yoon Sung Bae, Sang-Soo Choi, Bryan Barnes, Richard M. Silver, Martin Sohn
The deep ultraviolet (DUV) scatterfield imaging microscopy technique enables accurate dimensional measurements of periodic nanostructures with sub-nanometer sensitivity to support semiconductor device manufacturing. A parametric sensitivity analysis for

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
