Thermo-mechanical characterization of PHB/PCL blend incorporated with carbon nanotubes

eXPRESS Polymer Letters
Polyhydroxybutyrate (PHB) is a polymer with great application potential; however, its brittleness and low mechanical strength restrict its use in many fields. This study investigated a strategy to overcome the mechanical limitations of PHB by blending it

Manipulation of Polyhydroxybutyrate Properties through Blending with Ethyl-Cellulose for a Composite Biomaterial

International Journal of Polymer Science, 2011
Polyhydroxybutyrate (PHB) is widely used as a biomaterial in medical and tissue-engineering applications, a relatively high crystallinity limits its application. Blending PHB with ethyl-cellulose (EtC) was readily achieved to reduce PHB crystallinity and

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).

Robust Bioconjugated Antigens Induce Immune Responses Preventing Malaria Infection and its Transmission

Small, Volume 22, Issue 28, 18 May 2026.
Engineered malaria antigens enable in vivo bioconjugation to submicron biopolymer particles in E. coli. Two antigens are co‐tethered at high density and defined stoichiometry. The resulting thermostable particles elicit strong, durable antibody and T‐cell responses, conferring robust protection and blocking mosquito transmission.
