Photopolymer Additive Manufacturing 2025 Workshop Report: Building a Unified Vision from Research to Regulation

June 10, 2026
Author(s)
Callie Higgins, Jason Killgore, Mike Idacavage, Vince Anewenter, Mickey Fortune, Gary Cohen, Perri Katzman, Jessica Hemond, Spencer Loveless, Michael Gould
The third biannual Photopolymer Additive Manufacturing Alliance Workshop was held on September 15-16, 2025, at the University of Colorado Boulder to continue its mission of advancing photopolymer additive manufacturing (PAM). Building on the 2023 PAMA

In-process optical measurement and compensation of machine tool thermal deformations

June 9, 2026
Author(s)
Zongze Li, Aaron Cornelius, Gonzalo Reyes, Edward Kinzel, Ryuta Sato, Gregory Vogl, Robert Landers
Machine tool deformations due to thermal loads from motors and part processing, as well as from changing ambient temperature, can dominate the machine tool's volumetric error and substantially affect part quality. Current methods struggle to take

Spatial heterogeneity in polymer blends and its impact on dynamics

June 6, 2026
Author(s)
Bret Tantorno, Tuyen Truong, Lori Hoover, Gregory McKenna, Ran Tao, Fan Zhang
The relationship between dynamic and spatial heterogeneity in polymer blends is still not fully understood, yet it plays a crucial role in our understanding of their viscoelastic properties. Here, we report the results of an investigation of the

Analysis of the Manufacturing USA Occupation and Competency Framework

June 2, 2026
Author(s)
Joseph Long, Brad Conrad, Amelia Stephens, Aaron Bell, Jeremiah Forshey, Robert Foy, Ashley Smith-Schoettker
This analysis describes the most common entry-level occupations in advanced manufacturing across the technology areas associated with the Manufacturing USA network through 2030. This review identifies 132 occupations connected to 235 KSAs (knowledge

Plastic ingestion by North Pacific Garbage Patch fishes: Highest occurrences and quantities in upper trophic pelagics

June 1, 2026
Author(s)
Katherine Shaw, Zachary Bramble, Sarah-Jeanne Royer, Matthias Egger, Matthew Iacchei, Jennifer Lynch, K David Hyrenbach
Plastic marine debris (PMD) is rapidly accumulating in the North Pacific Subtropical Gyre, exposing fishes living in the North Pacific garbage patch (NPGP) to extremely high PMD concentrations. We dissected and analyzed the gastrointestinal tract of 204

Accelerating in situ X-ray tomography using sparse projections and deep learning

May 30, 2026
Author(s)
Nathan Johnson, Orion Kafka, Newell Moser
In situ X-ray tomography experiments provide powerful insight into material deformation and damage evolution under mechanical load. However, laboratory-based tomography instruments often suffer from long acquisition times that limit temporal resolution. In

Analog quantum simulator of a quantum field theory with fermion-spin systems in silicon

May 29, 2026
Author(s)
Ali Rad, Alexander Schuckert, Eleanor Crane, Gautam Nambiar, Fan Fei, Jonathan Wyrick, Richard Silver, Mohammad Hafezi, Zohreh Davoudi, Michael Gullans
Simulating fermions coupled to large spin degrees of freedom represents a promising application for quantum simulators, given its relevance to lattice gauge theories. Mapping fermions to qubits is challenging in dimensions larger than one, complicating the

Variant Allele Characterization in STR Markers Using Next Generation Sequencing

May 29, 2026
Author(s)
Lauren Mullen, Carolyn Steffen, Katherine Gettings, Kevin Kiesler, Peter Vallone
Traditionally, Sanger sequencing was used to characterize reference materials and confirm discordant allele calls from different STR typing kits at the National Institute of Standards and Technology (NIST). Sequencing can also identify genomic variations

130-nm CMOS-Integrated Superparamagnetic Tunnel Junction-Based p-bit

May 26, 2026
Author(s)
Nuno Cacoilo, Juyoung Yoon, Advait Madhavan, Jabez McClelland, Shun Kanai, Shunsuke Fukami, William Borders
Probabilistic computers offer promising solutions for computationally hard problems in domains such as combinatorial optimization and machine learning. A key building block in these systems is the probabilistic bit (p-bit), which relies on

A generative pre-trained transformer with Kerr-soliton attention

May 22, 2026
Author(s)
Lindell Williams, Yan Jin, Scott Papp
Artificial intelligence systems, particularly through generative pre-trained transformers (GPTs), have enabled capability-rich language models, but their operation incurs substantial costs in digital computation, memory, and data movement. Attention is a

A spectroscopic dataset for known provenance and1 post-consumer textiles

May 22, 2026
Author(s)
Katarina Goodge, Alexander Landauer, Cecelia Vederman, Amanda Forster
Near infrared (NIR) spectroscopy is a rapid, non-invasive technique often used for chemical bond structure identification, making it a prime candidate for feedstock identification and validation for industrial processes involving polymers. It has rapidly

Procedural Rigor and Reproducibility in NMR Metabolomics: Community Practices and Challenges

May 22, 2026
Author(s)
Tracey Johnston, Leo Cheng, Anastasios Theodorou, Marie Phelan, Goncalo J Gouveia, Robert Powers, Panteleimon Takis, Fabio Casu, Robert Brua, Gagandeep Kaur, Wimal Pathmasiri, Teklab Gebregiworgis, Valerie Copie
Nuclear magnetic resonance (NMR) spectroscopy is a fundamental tool of metabolomics, valued for its reproducibility, quantitative accuracy, and broad applicability across biological and clinical sciences. However, despite its strengths, methodological
