Long‐Time Thermal Aging of Perfluoroalkoxy Polymers for Electrical Insulation: Structural and Physical Properties Evolutions

Journal of Applied Polymer Science, EarlyView.
This work focuses on the investigation of the influence of a long‐time exposition to accelerated thermal aging on the physicochemical structure and properties of PFA. Results show a decrease in the melting temperature and crystal ratio due to chemical aging.

Valorization of Post‐Consumer Waste From Metallized Flexible Packaging and Industrial EPM Waste: Development of Sustainable Composites

Journal of Applied Polymer Science, EarlyView.
Post‐consumer metallized flexible packaging waste and industrial EPM waste are transformed into sustainable composites through mechanical recycling. The incorporation of 30 wt% EPM provides the most favorable balance between stiffness, ductility, and impact resistance, achieving 53.36 kJ/m2.

Wood Sawdust as a Low‐Cost Filler in Whole‐Tire Reclaimed Rubber: Mechanical Characterization and Factory‐Scale Cost Analysis

Journal of Applied Polymer Science, EarlyView.
Whole‐tire reclaimed rubber is upgraded with wood sawdust, a carpentry by‐product available at no cost, across loadings from 0 to 20 wt%. At 5 wt%, tensile strength, elongation, hardness, viscosity, and water absorption all stay within commercial specification, and real factory data show an annual production saving near $62,000 with no capital ...

In Situ Generation of a Robust Gel Polymer Electrolyte From a Poly(Ethylene Carbonate)‐Hydrogenated Nitrile Butadiene Rubber Containing Thermoplastic Vulcanizate Electrolyte

Journal of Applied Polymer Science, EarlyView.
A gel polymer electrolyte thermoplastic vulcanizate (GPE–TPV) was prepared by blending HNBR and PEC by melt extrusion then thermally decomposing PEC to yield liquid EC. EC is absorbed into the crosslinked HNBR, yielding an electrolyte that is mechanically and electrochemically stable enough to permit cycling in a LiFePO4–Li half‐cell.

Material Characterization of Lignin‐Filled Polypropylene Composites

Journal of Applied Polymer Science, EarlyView.
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.
