Summary: Talipot starch-based biocomposite films were prepared by incorporating plant mucilage derived from various sources. The addition of plant mucilage enhanced the crosslinking and relative crystallinity of the films. The biocomposite films exhibited similar structures to native starch films with finer corrugations. The moisture content decreased while thickness and opacity increased with the addition of plant mucilage. BSM-TSF showed the highest tensile strength among all biocomposite films and demonstrated improved thermal and biodegradation stability.

Summary: The demand for green biodegradable plastics as a replacement for synthetic ones is increasing due to the current environmental threats. This study investigates the properties of bioplastics made from yam and potato tuber peels, including their morphology, physical, mechanical, and thermal characteristics. These bioplastics offer a sustainable solution to the problem of plastic waste and have potential applications in edible food packaging. The research found that bioplastics produced using hydrochloric acid exhibited darker color and higher modulus of elasticity compared to those produced using acetic acid. Additionally, waste potato peel-based bioplastics showed better water absorption and thermal stability than yam-based ones. Among all the bioplastics produced, waste potato peel-based bioplastics produced using hydrochloric acid exhibited the best physical, mechanical, and thermal properties.

Summary: Since the 1950s, 8.3 billion tonnes of plastics have been produced, with around 5 billion tonnes turning into waste in oceans and natural environments, posing serious threats to ecosystems. This article presents a fast and scalable process to transform microalgae into a self-bonded and compostable bioplastic, with superior mechanical properties compared to other biobased plastics. The bioplastics made from spirulina algae exhibit flexural modulus and strength in the range of 3-5 GPa and 25.5-57 MPa respectively, and show promise as consumer plastics due to their machinability and self-extinguishing properties.

Summary: Finding an environmentally acceptable solution to the increasing plastic demand and ecological destruction is crucial. This study focused on the environmentally friendly production of bioplastic samples derived from corn starch, rice starch, and tapioca starch. By testing the physical and chemical properties of the samples produced with different ratios of fillers and plasticizers, it was found that starch-based bioplastics are a better alternative material for the packaging sector.

Summary: This article focuses on the properties and applications of metal alloys used for manufacturing coronary artery stent platforms, with a specific emphasis on cobalt-chromium and commercially pure titanium. Cobalt-chromium alloys have advantages in terms of flexibility and radiopacity, but concerns exist regarding their cytotoxicity. Commercially pure titanium exhibits excellent corrosion resistance and biocompatibility, but suffers from inadequate mechanical strength and poor radiopacity during stent development. To overcome these limitations, the study investigates strategies such as surface treatment, polymer coating, and warm treatment for titanium. The importance of radiopacity and radial strength in post-clinical imaging techniques, as well as the compatibility of metals with imaging devices, is also discussed.
