Alumina–Silica Hybrid Reinforcement in Jute/Epoxy Composites: Mechanical Characterization and Modified Rule of Mixtures for Strength–Toughness–Hardness Optimization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural fiber composites offer sustainable alternatives to synthetic materials but need performance enhancement for structural applications. This study investigates the mechanical behavior of jute fiber–reinforced epoxy composites modified with alumina–silica hybrid fillers at varying compositions and loadings.

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,
