Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

Journal of Applied Polymer Science, Volume 143, Issue 35, September 15, 2026.
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.

Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, Volume 64, Issue 16, Page 3471-3491, 15 August 2026.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...

The dominance of non‐native plants over native plants increases with the number of global change factors

Oikos, Volume 2026, Issue 8, August 2026.
Global environmental change and plant invasion are both recognized as key indicators of the Anthropocene. Still, how the number of co‐acting global change factors (GCFs) influence invaded plant communities remains unclear, even though in nature GCFs usually act together rather than alone.

Distinct Temporal Mouthfeel in Dairy and Plant‐Based Milk Is Related to Their Rheological and Tribological Spectra

Journal of Texture Studies, Volume 57, Issue 4, August 2026.
Integrating microstructure, rheology, and tribology with sensory evaluation methods that capture dynamic changes in mouthfeel perception provides new insights into the gaps in sensory performance between plant‐based and conventional dairy products. ABSTRACT Despite an expanding market for plant‐based milks (PBMs), replicating the techno‐functional ...

Rational Design of Maleic Anhydride Grafted Ethylene/1‐Octene Modifier Systems for Polyamide 6 Impact Modification

Macromolecular Materials and Engineering, Volume 311, Issue 7, July 2026.
An industrially scalable and cost‐effective ternary design strategy for impact‐modified PA6 combines highly ductile ungrafted high‐octene EOR with MAH‐grafted low‐octene EOR of high strength. By decoupling modifier ductility and particle strength, it improves notched impact strength from −40°C to room temperature, enhances processability, reduces ...
