Interaction of Human umbilical vein endothelial cells and human hepatocytes celline on Gelatin-VEGF Microspheres and PHBV-HGF Microspheres in co-culture
… focused on the fabrication of HGF encapsulated PHBV microspheres and VEGF encapsulated gelatin microspheres to ensure controlled release of growth factors as the microspheres degrade during cell culture. Blank microspheres and 2D cell cultures were used as controls. Characterization of the …

Extrusion foaming of bioplastics for lightweight structure in food packaging
… to overcome the key drawbacks of the pure PHBV, namely low crystallisation rate, tensile strength, ductility, melt viscosity, thermal stability and high materials cost. The physical, mechanical, thermal, and rheological properties of the pure PHBV were studied systematically first to lay a …

Harnessing <i>Haloferax mediterranei</i> for Bioplastic Production from Organic Waste
… poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) synthesis metabolism of this halophilic archaeon, identifying key technical challenges such as waste variability, feedstock pretreatment, and the needs for efficient volatile fatty acid (VFA) generation. Then, ex-situ VFA recovery from …

Blends of Biodegradable Thermoplastics With Lignin Esters
… (PHB), poly-hydroxybutyrate-co-valerate (PHBV), and a starch-caprolactone blend (SCL). Lignin esters included acetate (LA), butyrate (LB), hexanoate (LH), and laurate (LL). Blend characteristics were analyzed in terms of thermal and mechanical properties. The results indicate widely …

Development of biomaterials from sustainably produced macroalgae feedstocks
… poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) reinforced with cellulose nanofibers derived from a naturally co-existing mixed algae culture of Cladophora sp. and Rhizoclonium sp. The production and characterization of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-oxidized Cellulose …

Thermal spray of a drug delivery system onto femoral orthopaedic implant
… vehicle. The proposed materials (PCL, PMMA and PHBV) consisted of biodegradable and non-biodegradable polymers (used separately or as a composite) that are widely used as drug delivery systems. The method used to apply these drug delivery systems in this project was flame spraying, due to its …

Biofilm formation by Shewanella oneidensis MR-1 towards fundamental understanding of anode respiring communities
… to novel biocompatible electrode materials (PHBV-CF) and combined with a laccase catalyzed oxygen reduction cathode in a hybrid biological fuel cell. In comparison to the encapsulated anodes, additional experiments were performed to optimize the growth conditions at which S. oneidensis will …

Biosynthesis and characterisation of polyhydroxyalkanoate biopolymers and their oligomers for circular economy
… production studies, thermal degradation of PHBV to PHA oligomers proved to be a better method for obtaining PHA oligomers than from yeast biomass in brewery waste. The outcome from this study provides preliminary evidence for further developmental work on the cost-effective microbial …

The synthesis of biodegradable polymers using aluminium alkoxide initiators
… developed. A di-hydroxy functional pre-polymer, PHBV, was reacted with an aluminium alkyl to form a di-alkoxide macroinitiator which was subsequently used as an initiator for the polymerisation of ε-caprolactone to form an ABA type tri-block co-polymer. The molecular weight and other properties …
