Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, EarlyView.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

Ultrasound Measurements, Physico‐Chemical Characterization and Biological Evaluation of Magnesium Hydroxyapatite for Biomedical Applications

Macromolecular Symposia, EarlyView.
ABSTRACT In this study, 15MgHAp (xMg = 0.15) was synthesized by an adapted method, lyophilized, and characterized to evaluate its physicochemical and biological properties. The ultrasound measurements (US) evaluated the stability of the resulting MgHAp gel. Complementary surface information was obtained using a scanning ultrasonic microscope (SUM). The
