June 29, 2026
Author(s)
Giovanni Di Cristina Torres, Erik Johnsson, Eric Mueller, Matthew Bundy, Anthony Chakalis, Marco Fernandez, Artur Chernovsky, Aika Davis, Anthony Hamins
A series of experiments is reported on the burning behavior of 3.3 m to 7.4 m tall, Douglas-fir trees with the dry basis moisture content varying from 7 % to 55 %. The results quantified the transient, peak, and total heat release rates (HRR) as well as

Crack Formation Modeling in Concrete Affected by Iron-Sulfide Reactions

June 24, 2026
Author(s)
Osamah Dehwah, Nicos Martys, Edward Garboczi, Michael Mengason, Patrick Dixon, Stephanie Watson
Damage in concrete containing sulfide-bearing aggregates has become a critical issue in several countries such as the USA, Canada, and Ireland. This deterioration unfolds over decades and is driven by oxidation reactions in sulfide-bearing aggregates

Cybersecurity for the Water and Wastewater Sector:

June 24, 2026
Author(s)
CheeYee Tang, Jeffrey Marron, Stephanie Saravia, Philip Fenimore, Bob Stea, Chalessa White, John Wiltberger
The Water and Wastewater Systems (WWS) sector plays an important role in our national critical infrastructure in supplying clean water to our communities and removing harmful materials from wastewater. The WWS sector is undergoing a digital transformation

Defect states in the electronic structure of Ga2O3 transparent conductive oxides

June 23, 2026
Author(s)
Elizaveta Pyatenko, Constantin Wansorra, Ralph Steininger, John Vinson, Wolfram Witte, Dimitrios Hariskos, Michael Powalla, Clemens Heske, Lothar Weinhardt, Dirk Hauschild
Defect states are crucial in many electronic devices. Oxygen vacancies, for example, are common in transparent conductive oxides and can both be beneficial (e.g., as dopant to enhance conductivity) as well as detrimental (e.g., leading to reduced device

Literature Review of Fabricated Artifacts for X-ray Computed Tomography

June 22, 2026
Author(s)
John Wu, Felix Kim
This report provides a comprehensive literature review of fabricated artifacts, commonly referred to as phantoms, used for the performance evaluation of X-ray computed tomography (XCT) systems. As XCT is increasingly adopted for high-precision metrology in

Structure-Property Relationships for Biodegradability in Copolyesters

June 18, 2026
Author(s)
Katharina Fransen, Julia Casey, Gabrielle Godbille-Cardona, Natalie Mamrol, Jiale Shi, Alex Zappi, Jignesh Mahajan, Jiarui Lu, Debra Audus, Bradley Olsen
With growing concerns about increasing plastic pollution, interest in biodegradable polymers, particularly polyesters, continues to grow. Copolymerization is an important molecular handle to tune properties to achieve material performance and

Towards a Digital Twin of a Coordinate Measuring Machine

June 18, 2026
Author(s)
Deogratias Kibira, Guodong Shao, Rishabh Venketesh, Emma Bair
This paper presents the development of a digital twin for a Coordinate Measuring Machine (CMM) using open standards and supporting technologies. The approach is demonstrated through a case study in which a compact CMM inspects a machined part. Inspection

A Switchable Longitudinal & Shear BLS Microscope for Comprehensive Modulus Imaging of Semiconductor Packaging Materials

June 17, 2026
Author(s)
Andrew Gayle, Sebastian Engmann, Ran Tao, Andrew Korovich, Polette Centellas, Yvonne Gerbig, Christopher Soles, Chris Michaels
Brillouin light scattering (BLS) offers an optical, noncontact, nondestructive method for probing the mechanical properties of next-generation semiconductor packaging materials. In this work, a switchable BLS microscope with both backscattered and off-axis

Michael Fagan, Jeffrey Marron, Barbara Cuthill
This report summarizes the presentations and feedback received by the NIST Cybersecurity for the Internet of Things (IoT) Program at the hybrid workshop on "Cybersecurity for IoT Workshop: Future Directions" held March 31 – April 1, 2026. The purpose of

Erratum: "Anisotropic coarse-grain Monte Carlo simulations of lysozyme, lactoferrin, and NISTmAb by precomputing atomistic models" [J. Chem. Phys., 161, 094113 (2024)]

June 15, 2026
Author(s)
Harold Hatch, Christina Bergonzo, Marco Blanco, Guangcui N. Yuan, Sergei Grudinin, Mikael Lund, Joseph E. Curtis, Alexander Grishaev, Yun Liu, Vincent Shen
The authors initiate a correction to Hatch et al. [J. Chem. Phys., 161, 094113 (2024)]. If the particles are of the same type, particle swap symmetry was improperly applied by limiting the azimuthal angle to values of 0 to pi by choosing the reference
