Author(s)
William Dunaway, Cheyney O'Fallon, Wenqi Guo, Thomas Roth
In August 2024, the Smart Connected Systems Division of the National Institute of Standards and Technology (NIST) conducted a workshop entitled, "Whole Community Preparedness in Smart Cities and Communities." The purpose of the workshop was to determine

Hydrolytic and Enzymatic Degradation of Linear Segmented Polyurethane Block Copolymers Studied by ToF-SIMS and Atomic Force Microscopy

November 26, 2025
Author(s)
Gilad Zorn, Felix Simonovsky, Jeremy Brison, Shinichiro N. Muramoto, Buddy Ratner, David Castner
Hydrolytic and enzymatic degradation of linear segmented polyurethanes with differing compositions were studied by atomic force microscopy and time-of-flight secondary ion mass spectroscopy. Poly(ester urethane urea)s (PEUUs) with two different molecular

Wind-Driven Fire Spread to a Structure from Composite Fences

November 26, 2025
Author(s)
Kathryn Butler, Erik Johnsson, Marco Fernandez, Shonali Nazare, Alexander Maranghides
Field observations show that combustible landscaping features are a common pathway leading fire spread directly to homes during wildland-urban interface (WUI) fires. NIST is studying how these features near a home burn to better understand their levels of

Towards Automating IoT Security: Implementing Trusted Network-Layer Onboarding

November 25, 2025
Author(s)
Michael Fagan, Jeffrey Marron, Murugiah Souppaya, Paul Watrobski, Karen Kent, Blaine Mulugeta, Susan Symington
This document provides an overview of trusted Internet of Things (IoT) device network-layer onboarding, a capability for securely providing IoT devices with their local network credentials in a manner that helps to ensure that the network is not put at

Trusted Internet of Things (IoT) Device Network-Layer Onboarding and Lifecycle Management: Enhancing Internet Protocol-Based IoT Device and Network Security

November 25, 2025
Author(s)
Jeffrey Marron, Michael Fagan, Murugiah Souppaya, Paul Watrobski, Blaine Mulugeta, Susan Symington, Joshua Klosterman, Charles Rearick, Chelsea Deane, Dan Harkins, Danny Jump, Michael Richardson, Andy Dolan, Kyle Haefner, Craig Pratt, Darshak Thakore, Peter Romness, Tyler Baker, David Griego, Brecht Wyseur, Nick Allott, Alexandru Mereacre, Ashley Setter, Julien Delplancke, Steve Clark, Mike Dow, Steve Egerter, Karen Kent
Establishing trust between a network and an Internet of Things (IoT) device (as defined in NIST Internal Report 8425) prior to providing the device with the credentials it needs to join the network is crucial for mitigating the risk of potential attacks

Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms

November 24, 2025
Author(s)
Noah Schlossberger, Tate McDonald, Kevin Su, Rajavardhan Talashila, Robert Behary, Charles L. Patrick, Eugeniy E. Mikhailov, Seth Aubin, Irena Nokivoka, Christopher Holloway, Nikunjkumar Prajapati
Imaging of electric and magnetic fields is limited by the fact that conventional field probes rely on conductive elements that perturb the fields they are meant to measure and require either spatial scanning or arrays to produce field maps. Atomic sensors

Safeguarding International Science: Research Security Framework

November 21, 2025
Author(s)
Gregory Strouse, Claire Saundry, Timothy Wood, Philip Bennett, Mary Bedner, Jeremy Schultz
The U.S. science and research ecosystem retains its leadership by actively engaging with the global community through the conduct of mutually beneficial collaborative research and the welcoming of international scientists. Coupled with that, the national

Strain Mediated Voltage Control of Magnetic Anisotropy and Magnetization Reversal in Bismuth Substituted Yttrium Iron Garnet Films and Meso-structures

November 21, 2025
Author(s)
Walid Al Misba, Miela Gross, kensuke hayashi, Daniel Gopman, Caroline Ross, Jayasimha Atulasimha
We report on magnetic anisotropy modulation in Bismuth substituted Yttrium Iron Garnet (Bi-YIG) thin films and mesoscale patterned structures deposited on a PMN-PT substrate with the application of voltage-induced strain. The Bi content is selected for low

Multigas adsorption with single-site cooperativity in a metal-organic framework

November 20, 2025
Author(s)
Kurtis M. Carsch, Henry Z. Jiang, Ryan Klein, Andrew S. Rosen, Peyton Summerhill, Jesse L. Peltier, Adrian J. Huang, Ryan A. Murphy, Matthew N. Dods, Hope A. Silva, Zikri Hasanbasri, Hyunchul Kwon, Sarah H. Karstens, Yuto Yabuuchi, Jonas Boergel, Jordan W. Taylor, Katie R. Meihaus, Karen C. Bustillo, Andrew M. Minor, Kristen A. Persson, Craig Brown, R. D. Britt, Nicholas P. Stadie, Jeffrey Long
Cooperative gas adsorption in metal–organic frameworks (MOFs) is a rare phenomenon that generally involves long-range communication between multiple binding sites. We demonstrate a MOF containing cobalt(II)–methyl sites that selectively and reversibly

Environmental Measurements: A Needs Assessment

November 19, 2025
Author(s)
Julia Marrs, David Allen, Gerald Fraser
A summary is provided of the presentations, discussion, and findings from a two-and-a-half-day workshop on environmental measurements focusing on needs for new measurement science and measurement standards to support the characterization of ecological

Evaluation of sources of variability in a nitric oxide screening assay for engineered nanomaterials

November 18, 2025
Author(s)
Tariq Fahmi, Robert Gutierrez, Ana Barrios, Tae Joon Cho, John Elliott, Sanghamitra Majumdar, Bryant Nelson, Aaron Johnston-Peck, Alessandro Tona, Anil Patri, Elijah Petersen
Assays to detect potential biocompatibility issues can play a key role in supporting the development of new technologies such as medical products containing engineered nanomaterials (ENMs). In this paper, we describe an evaluation of sources of uncertainty

Robust Two-Qubit Geometric Phase Gates using Amplitude and Frequency Ramping

November 18, 2025
Author(s)
Christina Bowers, Deviprasath Palani, John Barta, Tyler Guglielmo, Stephen Libby, Dietrich Leibfried, Daniel Slichter
We demonstrate a method for generating entanglement between trapped atomic ions based on adiabatically ramped state-dependent forces. By ramping both the amplitude of the state-dependent force and the motional mode frequencies, we realize an entangling

Towards a quantum repeater using a surface-trap-integrated microcavity and trapped ions

November 18, 2025
Author(s)
Lindsay Sonderhouse, Margaret Bruff, Kaitlyn David, Daniel Slichter, Dietrich Leibfried
Trapped ions are a leading candidate for the "stationary qubits" of a quantum network. However, thus far remote entanglement rates have primarily been limited by low photon collection efficiency. In this work, we propose an architecture for a long-range

Compatibility of trapped ions and dielectrics at cryogenic temperatures
