Summary: The effect of sulfur on the glass forming ability, thermal stability and mechanical properties of Ti33.4Zr33.3Cu33.3 eutectic alloy was studied. A novel region of bulk glass formation was found in the Ti-Zr-Cu-S system, but brittle fracture behavior was dominant. Various alloying strategies were employed to improve mechanical properties and a compositional transition from brittle to ductile fracture has been identified. The study indicates a strong correlation between primary crystallizing phase and thermal stability, both pointing to the frozen short-range order in the amorphous state which determines the mechanical properties.

Summary: Gelatin methacryloyl (GelMA) hydrogels are widely used for drug delivery and tissue engineering due to their biocompatibility, biodegradability, and controllable photocurable efficiency. This study investigated the structural and property differences of GelMA synthesized in phosphate buffer solution (PBS) and carbonate-bicarbonate buffer solution (CBS). GelMA synthesized in PBS exhibited distinct physical structures and better properties, while GelMA synthesized in CBS showed advantages in swelling performance and microstructures. Additionally, GelMA synthesized in PBS with a high degree of methacryloylation showed great potential for 3D bioprinting.

Summary: This study demonstrates that material properties of biocomposites with high Organosolv lignin content can be tuned by carefully selecting thermal and mechanical energy input during compounding. The coupling reactions of Organosolv lignin at temperatures below 200 degrees C can significantly increase molecular weight. The biocomposites obtained at higher specific energy input showed increased stiffness and dynamic stiffness.

Summary: Bioplastics have a medium score for mechanical performance and a high score for biodegradability compared to petroleum-based plastics. Enhancing the mechanical performance of bioplastics is more achievable than providing sufficient biodegradability, due to the inverse relationship between mechanical performance and biodegradability. Both macro and micro strategies are available to address this challenge and improve the production, processability, and performance of bioplastics.
