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

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

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

Certification of Standard Reference Material 1474c, a Polyethylene Resin

May 14, 2026
Author(s)
Kalman Migler, Nathanael Heckert, Suzanne Thornton
The melt flow rate of Standard Reference Material (SRM) 1474c, a linear polyethylene (narrow MWD ethylene-hexene copolymer) resin, was determined to be 5.04 g/10 min at 190 °C under a load of 2.16 kg using the ASTM Method D 1238-23a. The average is a

Nanoscale mapping of composition and orientation in electrospun polymeric nanofibers loaded with carbon atomic wires

April 4, 2026
Author(s)
Simone Melesi, Devon Jakob, Jeremy Schultz, Adam Biacchi, Piotr Pinkowski, Bartlomiej Pigulski, CHIARA CASTIGLIONI, Chiara Bertarelli, Slawomir Szafert, Carlo Spartaco Casari, Andrea Centrone
This study yields a comprehensive nanoscale investigation of the composition and molecular orientation of electrospun poly(methyl methacrylate) (PMMA) nanofibers containing halogen-terminated carbon atomic wires (CAWs), a finite-length analog of the

Control of Dynamic Composites through Filler Surface Chemistry

February 6, 2026
Author(s)
Neil Dolinski, Lily Alperstein, Ran Tao, Anthony Kotula, Hojin Kim, Kyle Petersen, Elina Ghimire, Charlie Lindberg, Julia Murphy, Kexin Li, SJ Sibener, Aaron Forster, Stuart Rowan
The addition of hard fillers to polymeric networks allows for enhancement of mechanical properties, generally at the expense of extensibility. In the case of filled elastomers (such as tires), the hard particles cause damage to the underlying network when

Survey of agricultural plastic waste in the American Midwest: usage and disposal

January 1, 2026
Author(s)
Julie Rieland, Christina Gore, Kalman Migler, Kathryn Beers
An estimated 4 % of global plastics are used for agricultural applications in forms such as films, jugs, fence posts, and hoses. However, there is limited data on actual use, and more importantly on its fate at end of life. We first present a comprehensive

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

Charge-state dependent ion condensation near conjugated polymer backbones

November 15, 2025
Author(s)
Dilara Meli, Quentin Thomas, Guillaume Freychet, Lucas Flagg, Iain McCulloch, David Beljonne, Lee Richter, Jonathan Rivnay
Despite the technological appeal of organic mixed ionic/electronic conductors (OMIECs) for a range of applications, a deep understanding of the fundamentals of mixed charge transport in these materials, especially regarding the ionic component, is lacking

The structure and morphology of single-component oligomeric RNA delivery vectors derived from amphiphilic Charge-Altering Releasable Transporters

November 6, 2025
Author(s)
Paul Hurst, Yuan Jia, Summer Ramsay-Burrough, Rebecca McClellan, Joshua Arens, Samuel Khasnavis, Trevor del Castillo, Mahmoud AbdElwakil, Michael Lueckheide, Vivek Prabhu, Robert Waymouth
Recent advances in nucleic acid delivery have been inspired by efforts to mimic the function of natural viruses through the development of self-assemblies capable of transporting oligonucleotides across the cell and endosomal membranes. Lipid nanoparticles
