An Improved Robotic Workcell for Operational Technology (OT) Research

December 18, 2025
Author(s)
Timothy Zimmerman, Michael Pease, Michael Dawson
The National Institute of Standards and Technology (NIST) has constructed a discrete manufacturing workcell to support its operational technology (OT) and critical infrastructure research. This work is an improvement on the "Collaborative Robotics Testbed"

Twin-related grain boundary engineering of additively manufactured 316L stainless steel

December 1, 2025
Author(s)
Chenglu Tang, Jingfan Yang, Fan Zhang, Joseph Aroh, Ernest Porterfield, Barton Prorok, Xiaoyuan Lou
Twin-related grain boundary engineering (GBE) enhances the boundary-related degradation of materials, such as intergranular corrosion by incorporating a high density of twin boundaries. Conventional GBE typically requires one or multiple thermomechanical

Vibrometer-based Measurement of Turned Diameters

November 3, 2025
Author(s)
Aaron Cornelius, Osian Leahy, Burak Sencer, Gregory Vogl
Producing high-accuracy machined diameters requires the ability to check the part accuracy inside the machine tool so that process corrections can be made. Many different methods have been proposed for in situ diameter measurement, including optical

Geometric Red-Teaming for Robotic Manipulation

October 14, 2025
Author(s)
Divyam Goel, Yufei Wang, Tiancheng Wu, Guixiu Qiao, Pavlo Piliptchak, David Held, Zackory Erickson
Standard evaluation protocols in robotic manipulation typically assess policy performance over curated, in-distribution test sets, offering limited insight into how systems fail under plausible variation. We introduce a red-teaming framework that probes

REDUCING THE CYBERSECURITY RISKS OF PORTABLE STORAGE MEDIA IN OT ENVIRONMENTS

September 30, 2025
Author(s)
Michael Powell, Fenimore Philip, Stephanie Saravia
Though portable storage media are convenient, their unregulated use poses cybersecurity risks for organizations utilizing them in their OT environments. Procedural, physical, and technical controls are important because they can minimize the likelihood of

Reference Model for Electric Vehicle Battery Recovery in a Circular Economy

September 30, 2025
Author(s)
Matthew Triebe, Nehika Mathur, Ashley Hartwell, Katherine Morris
Electric vehicle batteries, which use a significant amount of critical materials, have the potential to be a reliable secondary source of those high-value materials at the end of their life to meet future needs. In this paper we present a reference model

Evaluation of Variations in Solution Annealing, Intercritical Annealing, and Aging Treatments on Cobalt-free Maraging Steels

September 22, 2025
Author(s)
Nicholas Derimow, Jake Benzing, Alec Saville, Cassidy Allen, Jordan Weaver, Nikolas Hrabe, Timothy Quinn, Timothy Weeks, Newell Moser, Chad Beamer, Christin Aumayr, Tilman Seifert, Michael Hirtler
This work is a compilation and summary of the quasi-static mechanical properties of a novel cobalt-free maraging steel, M789, that underwent a series of various heat treatments which included solution annealing, intercritical annealing, and aging

An Ontological Perspective on the Circular Biomanufacturing Process Design

September 1, 2025
Author(s)
Ana Nikolov, Milos Drobnjakovic, Boonserm Kulvatunyou, Stephen Granite, John Beverley
Constant advancements in biomanufacturing require operational frameworks that enable accurate comparisons between similar production processes for performance and cost optimization purposes. However, the extensive and heterogeneous nature of available data

Resolving Supply Chain Standards Heterogeneity to Enhance Supply Chain Flexibility

August 18, 2025
Author(s)
Elena Jelisic, Boonserm Kulvatunyou, Hakju Oh, Joshua Ki
Flexibility is identified as a mandatory characteristic of today's supply chains. There are a few aspects of supply chain flexibility identified in the literature, and one of them is flexible supply chain integration. The standard for exchanging supply

Advanced Characterization of the Cure Kinetics of a Liquid Encapsulant

June 26, 2025
Author(s)
Anthony Kotula, Ran Tao, Jianwei Tu, Young Lee, Gale Holmes
Liquid encapsulants are versatile packaging materials that provide electrical insulation and mechanical protection for microelectronic devices. As more advanced encapsulants are formulated to address modern packaging needs, advanced characterization

The trace of heat: on the predictive power of modeling transient diffusion

June 26, 2025
Author(s)
Vijaya Holla, Jesse Redford, Philipp Kopp, Stefan Kollmannsberger
The paper at hand evaluates the validity of the transient heat equation with phase change and temperature-dependent coefficients as a model to predict the evolution of melt pools for rapid turnaround scan strategies in a laser powder bed fusion (PBF-LB)
