Catalytic High‐Speed Reactive Extrusion for Polyethylene Mechanochemical Upcycling

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Twin screw extrusion at high speeds is a mechanochemical strategy for polyethylene recycling that takes advantage of high shear rates and intimate mixing with catalyst to induce structural transformations. This process intensification approach can lower the thermal energy requirements of chemical recycling, contributing to more economically viable and ...

Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics

Polymer Composites, Volume 47, Issue 8, Page 7675-7686, 20 April 2026.
Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was
