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

Elucidating the thermal properties and anomalous transport in the 18R polytype of SnSe2

May 30, 2025
Author(s)
Oluwagbemiga Ojo, Wilarachchige D. C. B. Gunatilleke, Winnie Wong-Ng, Tieyan Chang, Yu-Sheng Chen, Joshua Martin, Adam Biacchi, George Nolas
The 18R polytype of SnSe2 possesses unique structural features that can directly impact the transport properties and potential applications of interest; however, a comprehensive understanding of the intrinsic physical properties is lacking. We grew large

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

May 29, 2025
Author(s)
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

Towards an Understanding of Robotic Bin-Picking Throughput

May 22, 2025
Author(s)
Anirudh Krishnan Komaralingam, Prem Rachakonda, Kamel Saidi, Armin Khatoonabadi
NIST is leading and supporting multiple efforts to develop standards for 3D imaging systems used for industrial automation. There are few standards for verifying the performance of these systems and NIST is working with ASTM subcommittee E57.23 on

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

Multi-color solitons and frequency combs in microresonators

May 15, 2025
Author(s)
Curtis Menyuk, Pradyoth Shandilya, Logan Courtright, Gregory Moille, Kartik Srinivasan
Multi-color solitons that are parametrically created in dual-pumped microresonators generate interleaved frequency combs that be used to obtain combs at new frequencies and when synchronized can be used for low-noise microwave generation and potentially as

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
Author(s)
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

On-Chip Parametric Synchronization of a Cavity Soliton Microcomb

May 13, 2025
Author(s)
Gregory Moille, Pradyoth Shandilya, Miro Erkintalo, Curtis Menyuk, Kartik Srinivasan
Synchronization of oscillators is ubiquitous in nature. Often, the synchronized oscillators couple directly, yet in some cases synchronization can arise from their parametric interactions. Here, we theoretically predict and experimentally demonstrate the

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
