Trait‐associated pathway links plant diversity to litterfall phenology in a seasonally dry tropical forest

Oikos, EarlyView.
Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Effect of Carbon Nanotubes Incorporation on the Properties of a Photopolymer Resin Used in Vat Photopolymerization

Polymer Composites, EarlyView.
Preparation and experimental results of carbon nanotube/photopolymer resin nanocomposites fabricated by 3D printing. ABSTRACT This work examines the effect of the incorporation of carbon nanotubes (CNTs) into a photopolymer resin for the fabrication of nanocomposites via additive manufacturing (AM), using the masked stereolithography technique (MSLA ...

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

Polymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...
