Author(s)
Joseph Hodges, Zachary Reed, Katarzyna Bielska, Manfred Birk, Ruimin Guo, Gang Li, Jeong Sik Lim, Daniel Lisak, Georg Wagner
We present primary spectroscopic measurements of line intensities in the 3-0 vibrational band of 12C16O. This international measurement campaign was organized under the auspices of the Consultative Committee for Amount of Substance (CCQM) and involved six

Correlating Titanium Powder Manufacturing Methods and Resultant Particle Morphologies to Microstructural Properties, Particle Flight and Impact Velocity, and Bonding and Deposition Characteristics in Cold Spray Additive Manufacturing

January 23, 2025
Author(s)
Pranav Anumandla, Carlos Faggi, Sinan Muftu, Edward Garboczi, Newell Moser, Rachel Cook, Nicholas Derimow, Ozan Ozdemir
Unlike high temperature thermal spray processes and metal additive manufacturing methods that require extensive heat treatment, native particle microstructural properties in the feedstock powder have been shown to dictate the final thermomechanical

From Principles to Practice: Product Design Foundations for a Circular Economy

January 23, 2025
Author(s)
Buddhika Hapuwatte, Noah Last, Sami Karsli, Gaurav Aher, Katherine Morris, Vincenzo Ferrero
A circular economy moves from the current linear model of production and consumption, i.e., the take-make-use-dispose model, to one that uses resources efficiently, avoids pollution, and creates triple bottom line (i.e., economic, environmental, and social

ICSSC Biennial Progress Report for 2024: Report on Progress Towards Implementation of Executive Order 13717: Establishing a Federal Earthquake Risk Management Standard - Reporting Period: February 2, 2022 to February 1, 2024

January 23, 2025
Author(s)
John Harris, Steven McCabe
Executive Order (EO) 13717: Establishing a Federal Earthquake Risk Management Standard establishes minimum seismic requirements for new and existing buildings that will be constructed, altered, leased, financed, or regulated by the Federal Government

Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms

January 23, 2025
Author(s)
Noah Schlossberger, Andrew Rotunno, Stephen Eckel, Eric Norrgard, Dixith Manchaiah, Nikunjkumar Prajapati, Alexandra Artusio-Glimpse, Samuel Berweger, Matthew Simons, Dangka Shylla, William Watterson, Charles Patrick, Adil Meraki, Rajavardhan Talashila, Amanda Younes, David La Mantia, Christopher Holloway
Rydberg states of alkali-metal atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently, environmental blackbody radiation (BBR) can couple Rydberg states to

Scattering Insights into Shear-Induced Scission of Rodlike Micelles

January 23, 2025
Author(s)
Guan-Rong Huang, Ryan Murphy, Lionel Porcar, Chi-Huan Tung, Changwoo Do, Wei-Ren Chen
Studying the scission of rodlike micelles under mechanical forces is essential for understanding their stability and behavior in industrial applications. Mechanical stress can fragment these micelles, impacting performance. Investigating this process

Lattice Light Shift Evaluations In a Dual-Ensemble Yb Optical Lattice Clock

January 22, 2025
Author(s)
Tobias Bothwell, Roger Brown, Benjamin Hunt, Jacob Siegel, Tanner Grogan, Youssef Hassan, Kyle Beloy, Andrew Ludlow, Kurt Gibble, Takumi Kobayashi, Marianna Safronova, Sergey Porsev
In state-of-the-art optical lattice clocks, beyond-electric-dipole polarizability terms lead to a break-down of magic wavelength trapping. In this Letter, we report a novel approach to evaluate lattice light shifts, specifically addressing recent

Platinum Hydride Formation during Cathodic Corrosion in Aqueous Solutions

January 22, 2025

Thomas Hersbach, Angel T. Garcia-Esparza, Selwyn Hanselman, Thijs Hoogenboom, Ian McCrum, Dimitra Anastasiadou, Jeremey Feaster, Thomas Jaramillo, John Vinson, Thomas Kroll, Amanda Garcia, Petr Krtil, Dimosthenis Sokaras, Marc Koper
Cathodic corrosion is an electrochemical phenomenon that dramatically etches metals under commonly used electrocatalytic conditions. Though cathodic corrosion is thought to occur by forming a metal-containing anion, such an ion has not yet been observed

Software Metrics: Impossible, but Doable

January 22, 2025
Author(s)
Paul Black
Software metrics are theoretically impossible. However, there is tremendous benefit if we can assess properties of computerized systems. We review the elements that make it hard to computerized systems, in contrast with Civil Engineering or physical

Measuring the size of oil droplets in a flow cytometer using Mie Resonances

January 21, 2025

Richard E. Cavicchi, Dean Ripple, Joshua Welsh, Jerilyn Izac, Alexander Peterson, Aaron Goldfain, Wyatt N. Vreeland
An emulsion of silicone oil droplets in aqueous buffer produces a distinctive series of peaks or resonances in the side scatter histogram in a flow cytometer. As many as 12 peaks are observed in the violet-side scatter channel at 405 nm, with half that

On the response time constant of interface defects

January 21, 2025
Author(s)
Kin Cheung, Yu Xin Wen, Bing-Yue Tsui
Interface defect response time is a key parameter in some common electrical measurements of MOS devices, most notably the hi-lo CV measurement as well as the conductance measurement. A long established believe is that interface defects at energies close to
