Synthesis, Structure, and Properties of Polyhydroxybutyrate Derived from Azotobacter Vinelandii N‐15

open access: yesChemistryOpen, EarlyView.
The bacterium Azotobacter vinelandii N15 synthesizes polyhydroxybutyrate (PHB) from sugar production waste. The study reveals the molecular composition, crystallinity, and thermal behavior of the synthesized biopolymer. Mechanical tests demonstrated high tensile strength and relatively low elongation at break. These properties highlight PHB's potential

A two‐scale numerical analysis of intra‐yarn hybrid natural/synthetic woven composites

open access: yesPolymer Composites, Volume 46, Issue 5, Page 3989-4008, 10 April 2025.
Two‐scale homogenization model predicts mechanical properties and stress fields in intra‐yarn hybrid natural/synthetic woven composites. Abstract This paper investigates how combining natural and synthetic fibers within yarns, altering the degree of hybridisation, and varying weave architectures affect the homogenized elastic properties and stress ...

Opuntia ficus‐indica fruit by‐products as fillers for PLA‐based biocomposites: A comparison between glochids and peel

open access: yesPolymer Composites, EarlyView.
Utilizing cactus pear by‐products as fillers to develop PLA‐based biocomposites through melt mixing. Abstract This work explores sustainable and innovative solutions for valorizing by‐products from Opuntia ficus‐indica (cactus pear), a fruit widely grown in Sicily, the world's second‐largest producer. The peel and glochids of cactus pears were used for
