Out-of-plane electrochemical transport in all-thin-film hetero-epitaxial solid oxide fuel cell structures

June 6, 2025
Author(s)
Huairuo Zhang, Albert Davydov, Yangang Liang, Xiaohang Zhang, Yaoyu Ren, Seunghun Lee, H.M. Jaim, Eric Marksz, Takeuchi Ichiro, Haiyan Tan, Leonid Bendersky, Chris Kucharczyk, Ruiyun Huang, Sossina Haile
We have fabricated all-thin-film solid oxide fuel cell (SOFC) heterostructures and investigated the transport properties of Sm0.2Ce0.8O2-δ (SDC20) in an out-of-plane measurement geometry. The SOFC heterostructures, consisting of a bottom SrRuO3 (SRO) or

Implications of the Bullet Black Box Study

Bullet Black Box Working Group
The Bullet Black Box Working Group (BulletBB-WG) was convened to review the results of the NIST-Noblis Bullet Black Box Study, and assess the implications of that study on casework. This report includes the recommendations of the BulletBB-WG on how to

Metrics and Methodology for Hardware Security Constructs

June 5, 2025
Author(s)
Sanjay Rekhi, Kostas Amberiadis
Although hardware is commonly believed to be security-resilient, it is often susceptible to vulnerabilities arising from design and implementation flaws. These flaws have the potential to jeopardize not only the hardware's security, but also its operations

Picosecond Josephson samplers: Modeling and measurements

June 4, 2025
Author(s)
Logan Howe, Bart van Zeghbroeck, David Olaya, John Biesecker, Charles Burroughs, Peter Hopkins, Samuel Benz
Measurement of signals generated by superconducting Josephson junction (JJ) circuits require ultra-fast components located in close proximity to the generating circuitry. We report a detailed study of optimal design criteria for a JJ-based sampler that

Artificial Intelligence in the Fire Service: Considerations for Implementing Artificial Intelligence into Electronic Safety Equipment

June 3, 2025
Author(s)
Christopher Sampl, Clinton Smith, Albert Bahri, David Little, Richard Reel, Ash Liu, Jonathan Hodges, Ryan Falkenstein-Smith
Artificial Intelligence (AI) is becoming more pervasive in society, including public safety. There is a growing need for safety guidelines as AI becomes more integrated within electronic safety products used within the fire service. A group comprised of

Deciphering decomposition pathways of high explosives with cryogenic X-ray Raman spectroscopy

June 3, 2025
Author(s)
Oscar Parades Mellone, Michael Nielsen, Jeffrey Babicz, John Vinson, Trevor Willey, Dimosthenis Sokaras
We employed cryogenic X-ray Raman spectroscopy to investigate the early-stage decomposition of the high explosive molecule hexanitrohexaazaisowurtzitane (CL-20). By systematically varying the radiation dose under cryogenic conditions, we induced the

Sensitivity Study of Operating Conditions and Liquid Water Transport Behavior in an AEMFC Aided by Modeling and Neutron Radiography

June 1, 2025
Author(s)
Mrittunjoy Sarker, Felipe Mojica, Ami Neyerlin, Bryan Pivovar, Daniel Hussey, Jacob LaManna, David Jacobson, Po-Ya Chuang
Two types of anion exchange ionomers, powder and dispersion, are studied in this work. The gas diffusion electrode (GDE) with the dispersion-type ionomer exhibits strong hydrophobicity, thus not enabling sufficient ionic exchange during the potassium

280-GHz aluminum MKID arrays for the Fred Young Submillimeter Telescope

May 29, 2025

Anna Vaskuri, Jordan Wheeler, Jason Austermann, Michael Vissers, James Beall, James R. Burgoyne, Victoria Butler, Scott Chapman, Steve K. Choi, Abigail Crites, Cody J. Duell, Rodrigo Freundt, Anthony Huber, Zachary Huber, Johannes Hubmayr, Jozsef Imrek, Ben Keller, Lawrence Lin, Alicia Middleton, Michael D. Niemack, Thomas Nikola, Douglas Scott, Adrian Sinclair, Ema Smith, Gordon Stacey, Joel Ullom, Jeffrey Van Lanen, Eve Vavagiakis, Samantha Walker, Bugao Zou
First light observations of the 280 GHz instrument module of the Fred Young Submillimeter Telescope (FYST) in the CCAT Collaboration are expected in 2026. The focal plane of this module will consist of three superconducting microwave kinetic inductance

Fault-Tolerant Compiling of Classically Hard Instantaneous Quantum Polynomial Circuits on Hypercubes

May 28, 2025
Author(s)
Dominik Hangleiter, Marcin Kalinowkski, Dolev Bluvstein, Madelyn Cain, Nishad Maskara, Xun Gao, Aleksander Kubica, Mikhail Lukin, Michael Gullans
Quantum computational advantage is challenging to maintain asymptotically in the presence of noise. Fault-tolerant quantum computing provides a route to noiseless computations, but can have high overheads for generic algorithms. Here, we develop a fault

Controlling Impact Mitigation via Stimuli-Responsive Bouligand Nanostructures

May 16, 2025
Author(s)
Sujin Lee, Katherine Evans, Jeremiah Woodcock, Jan Obrzut, Liping Huang, Christopher Soles, Edwin Chan
Critical to their survival, natural organisms have developed exoskeletons that can withstand and inflict damage over their lifetime. The Bouligand structure of the exoskeleton plays a key role in toughness and damage resistance under external impacts

NIST Special Publication 260 NIST.SP.260-256 Certification of Standard Reference Material(R)s 3672a & 3673a: Organic Contaminants in Smokers' Urine (Frozen) & Organic Contaminants in Non-Smokers' Urine (Frozen)

May 14, 2025

Ashley Russell, Carolyn Burdette, Johanna Camara, Nathanael Heckert, Jennifer Hoguet, Kevin Huncik, Jared Ragland, Elena Wood
Standard Reference Material (SRM) 3672a Organic Contaminants in Smokers' Urine (Frozen) and SRM 3673a Organic Contaminants in Non-Smokers' Urine (Frozen) are intended for use in evaluating analytical methods for the determination of selected naturally

Selecting longitudinal community outcomes for resilience indicator validation

May 13, 2025
Author(s)
Donghwan Gu, Maria Dillard, Michael Gerst, Jarrod Loerzel
Assessing community resilience is a long-sought goal in multiple fields of study and practice. Community resilience frameworks have been designed to estimate the level of resilience through varying sets of cross-sectional indicators. However, community

A Fully Registered In-Situ and Ex-Situ Dataset for Metal Powder Bed Fusion Additive Manufacturing: Data Processing, Feature Extraction, Registration, and Uncertainties
