Summary: In order to ensure the quality of packaging process, the modern food industry requires versatile nanocomposites of polymers to inactivate germs linked to foods. Recently, zinc oxide nanocomposites with polyvinyl alcohol (PVA) have been used for food storage containers. The combination of zinc acetate and Capparis zeylanica leaf extract was used to create nanostructured ZnO, and ZnO/PVA nanocomposite films were developed. The synthesized ZnO and ZnO/PVA nanocomposites showed potential antibacterial efficacies against Gram + ve and Gram -ve bacteria, as well as efficient breakdown of methylene blue.

Summary: Co-doped ZnO nanocomposites were prepared via hydrothermal method on flexible substrates of polyethylene terephthalate-indium tin oxide (PET-ITO). The crystal structure, doping mechanism, and photocatalytic properties were intensively investigated. Compared to pure ZnO, Co-ZnO exhibited distinct photocatalytic activity with a degradation rate of 71.36% for methylene blue (MB) solution. The stable electronic structures and possible electronic sites for Co elements were discussed through theoretical calculations. Meanwhile, the mechanism to enhance the photocatalytic activity of ZnO was also discussed.

Summary: In this study, rare-earth (Sm3+) doped ZnO-SnO2 nanocomposites were synthesized using the sol-gel method to address issues such as wastewater treatment and bacterial infection. The formation of multi-phase nanocomposites of hexagonal ZnO and tetragonal SnO2 was confirmed by X-ray diffraction (XRD) analysis. The presence of Sm ions in the crystal lattice of the ZnO-SnO2 heterostructure was confirmed by morphology study, energy-dispersive analysis of X-ray (EDAX), and transmission electron microscopic (TEM) study. Photocatalytic degradation of environmental dyes and antibacterial behavior were also studied, showing enhanced efficiency and improved antibacterial properties in the nanocomposites.

Summary: The effect of different concentrations of zinc oxide on the dielectric properties of composite films was studied. It was found that increasing the zinc oxide content significantly increased the dielectric constant, AC conductivity, and loss tangent. A direct correlation between the dielectric parameter and the mean relaxation time of polymer chain segmental dynamics was observed, suggesting that the dielectric properties of these materials can be tailored by varying the amount of metal oxide filler for use in microelectronics.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
