Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

Journal of Applied Polymer Science, EarlyView.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, EarlyView.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.
