PE‐RT Grades for High‐Temperature Flexible Risers: Comparative Evaluation of Thermal, Mechanical, and Aging Performance

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 7, February 15, 2026.
Flexible riser structure, tie‐molecule arrangement, and XRD comparison of PE100, DOWLEX, and INTREPID polyethylene grades. ABSTRACT This study compares three polyethylene grades—a benchmark PE100 and two high‐temperature resistant polyethylene (PE‐RT) types (Type I and Type II)—to assess their suitability for flexible riser applications.

Sensitized Disequilibration of Water‐Soluble Azopolymers

open access: yesAngewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Disequilibration by sensitization under confinement (DESC) is a promising strategy for efficient visible‐light‐induced azobenzene E→Z isomerization. In this article, we explored key factors for adapting DESC to azopolymers, eventually achieving efficiencies up to 85% compared to direct excitation and laying the foundation for more complex systems ...

Effect of Few‐Layer Graphene (FLG) and Relative Photodegradation Depth on the Ductile to Fragile Transition of High‐Density Polyethylene

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 7, February 15, 2026.
Graphene is a good protector for UV degradation of polymers. ABSTRACT Photo‐stabilization is essential for thermoplastics in outdoor applications, as it extends service life by protecting polymer chains from UV‐induced degradation. Graphene has emerged as a multifunctional stabilizer with capabilities including UV screening, barrier effects, and ...

Artichoke Bracts and Stems Residues as Active Filler for Poly(Butylene Succinate‐Co‐Adipate) (PBSA) Composites: From Agro‐Waste to a New Sustainable Material

open access: yesPolymer Composites, Volume 47, Issue 3, Page 2376-2392, 10 February 2026.
PBSA‐based biocomposites made from artichoke bract and stem powders have been characterised and formulated for agricultural and food applications, such as active mulching films. ABSTRACT In the context of a growing bioeconomy and the drive for sustainable materials, new biocomposites were formulated by incorporating poly(butylene succinate‐co‐adipate) (

Plasmonic Hot‐Carrier Redox Enables Proton‐Coupled Electron Transfer at C─H Bonds

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Plasmonic hot carriers provide unprecedented control over coupled electron–proton transfer, enabling visible‐light activation of strong C─H bonds. Using an energy‐filter electrode, we reveal a stepwise electron‐then‐proton pathway and directly tune the underlying driving forces.

Twist and Shine: The Impact of Halogen Substitution on Thiele Hydrocarbon's Optical Properties

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Halogenation in Thiele hydrocarbons strongly influences structure and excited‐state dynamics. Depending on substitution, “boat” folded forms show large Stokes shifts and strong solvatochromism, while planar “butterfly” derivatives exhibit near‐unity photoluminescence yields.
