Novel processing of polyhydroxybutyrate with micro- to nanofibrillated cellulose and effect of fiber morphology on crystallization behaviour of composites

eXPRESS Polymer Letters, 2020
In this work, the intrinsic drawbacks of polyhydroxybutyrate (PHB) such as slow crystallization rate, secondary crystallization and brittle nature were improved by blending with bio-based fillers, i.e. nanofibrillated/microfibrillated cellulose (NFC/MFC).

Characterization of bioplastics produced by haloarchaeon Haloarcula sp strain NRS20 using cost-effective carbon sources

Materials Research Express, 2021
As good models for developing techniques, Haloarchaea are using as cell factories to produce a considerable concentration of bioplastics, polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), and polyhydroxyvalerate (PHV). In this study, low-cost carbon

Stimulus‐Induced Self‐Reinforcement in Supramolecular Bamboo Plastics toward Mechanical Robustness and Programmable Shapeability

Advanced Science, Volume 13, Issue 24, 27 April 2026.
A self‐reinforcement strategy is reported for the fabrication of bamboo plastics utilizing ethanol to induce the supramolecular network reconstruction of cellulose and polyacrylamide molecules. These bamboo plastics exhibit high mechanical strength, excellent thermal stability, resistance to low temperatures, and controllable shapeability.

Alveolar Bone Regeneration: Smart Biomaterials and Physical Stimulation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 4, April 2026.
ABSTRACT Large‐area bone loss from disease, trauma, or congenital defects requires surgical procedures and bone grafting. Alveolar bone loss from severe periodontal disease and non‐unions often demands immediate grafting. Treating large alveolar bone defects using grafts and substitutes is challenging due to the complex oral environment, infection ...

Natural Antioxidants as Thermal Stabilizers in Fully Biobased PHBV Compounds

Journal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
Polyhydroxyalkanoates (PHA) are promising biobased polymers but degrade easily under heat and oxygen. This study examines PHBV with natural antioxidants to enhance thermal stability during processing. Results show regenerative additives prevent degradation and the effectiveness is comparable to that of synthetic additives.
