Mechanical Properties and Thermo‐Oxidative Aging of Hybrid EPDM Formulations With Bio‐Based Oils

Journal of Applied Polymer Science, EarlyView.
This study evaluates bio‐based oil as an eco‐friendly replacement for paraffinic oil in EPDM rubber. While pure bio‐oil matches conventional mechanical properties, specific blends (25% and 75%) improve tensile strength and stiffness. The 50% blend requires tempering to optimize its sulfur network and morphology, eventually yielding a 35% strength ...

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.
