Fish loss in tropical coastal ecosystems can jeopardise nutrient supply to traditional fishing communities: A case study from Northeast Brazil

People and Nature, EarlyView.
Abstract Fisheries constitute one of the major benefits that oceans provide for people. Yet anthropogenic pressures and global changes are disrupting coastal systems, eroding marine biodiversity and threatening the food security of traditional populations.

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Synergistic Effect of Silanized Ramie Fiber and Montmorillonite Clay on the Mechanical, Thermal, and Dynamic‐Mechanical Properties of Polyester Composites

Polymer Composites, EarlyView.
Multiscale composite reinforced with silane‐modified ramie fiber and clay. ABSTRACT Multiscale polymer composites combining natural fibers and layered silicates can balance stiffness, toughness, and thermal stability when interfacial interactions are properly engineered.

Mechanical, Thermal, and Microstructural Evaluation of Bio‐Based Polyurethane Composites Reinforced With Woven Jute and Flax

Polymer Composites, EarlyView.
Graphical overview of the manufacturing and characterization of bio‐based polyurethane composites reinforced with woven jute and flax fibers produced by the VARTM process. Mechanical, thermal, and microstructural analyses reveal differences in stiffness, thermal stability, and interfacial behavior between the natural fiber composites.

Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

Polymer Engineering &Science, EarlyView.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.
