Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Impact of Fiber Treatments on the Properties and Aging Behavior of a Bio‐Composite Characterized From Nano‐ to Macro‐Scale

Polymer Composites, EarlyView.
From Posidonia oceanica seagrass fibers to sustainable bio‐composites: the role of alkaline treatment in composite performance and durability. ABSTRACT The valorization of the abundant marine residue Posidonia oceanica (PO) fibers, as a filler in a bio‐based epoxy matrix was investigated.

Direct Ink Writing 3D Printing of High Graphite Loading Polybenzoxazine Composite

Polymer Composites, EarlyView.
Graphite reinforced benzoxazine can be directly printed and crosslinked with help of an inert power support. This allows the graphite particle to form temporary scaffold and the printed shape to be preserved. ABSTRACT Polybenzoxazine is a class of high‐performance thermoset that can be reinforced with graphite to gain great thermal stability, chemical ...

Behavior of Injection‐Molded Nylon 6 Composites With Virgin and Field‐Exposed Waste‐Recycled Blends

Polymer Composites, EarlyView.
Recycling field‐exposed Nylon 6 composites for sustainable secondary applications. ABSTRACT Every year, more than 18,600 metric tonnes of glass fiber‐reinforced Nylon 6 composite waste from sucker rod guides used in downhole oil and gas applications are landfilled due to uncertainty about retained performance after prolonged service exposure.
