A zero trust architecture (ZTA) enables secure authorized access to enterprise resources that are distributed across on-premises and multiple cloud environments, while enabling a hybrid workforce and partners to access resources from anywhere, at any time

Partition Functions and Ideal-Gas Thermodynamics for Carbon Dioxide

June 10, 2025
Author(s)
Sergey Tashkun, Allan Harvey
We have constructed an effective Hamiltonian model for the rotational-vibrational states of molecular carbon dioxide. The model is constrained by a large amount of spectroscopic data for frequencies of rovibrational transitions. From this formulation, we

Residual stress-assisted static globularization in electron beam powder bed fusion Ti-6Al-4V from powder recovery and hot isostatic pressing

June 10, 2025
Author(s)
Nicholas Derimow, Thomas Berfield, Keenan Hanson, Jake Benzing, Nikolas Hrabe
The residual stresses from controlled powder recovery blasting on electron beam powder bed fusion (PBF-EB) Ti-6Al-4V were investigated via hole drilling, profilometry, and microscopy. After hot isostatic pressing, the near-surface lamellar the near-surface

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

June 6, 2025

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

June 5, 2025
Author(s)
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

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
