Summary: Recently, there is increasing interest in superhydrophobic magnesium-based implants due to their superior corrosion resistance and specific anti-bacterial adhesion properties. However, the superhydrophobic surface hinders cell adhesion and proliferation, limiting the application of these implants. In this study, a superhydrophobic composite coating composed of hydroxyapatite, bismuth sulfide, and lauric acid was prepared on AZ31B Mg alloys. The composite coating exhibited a water contact angle of 156 degrees, providing excellent corrosion resistance and antibacterial properties. Additionally, the surface of the coating could be transformed from superhydrophobic to hydrophilic upon near-infrared light irradiation, offering effective protection for the Mg alloy substrate. The coated Mg alloy demonstrated high antibacterial efficiency against Staphylococcus aureus and Escherichia coli, and good biocompatibility with favorable cell viability and early cell growth and adhesion.

Summary: This study provides a detailed interpretation of the role of Ga and Mn dopants, solid solubility mechanisms, charge compensation mechanisms, and antibacterial performance in CeO2 films. The results challenge the common assumption of the dominance of oxygen vacancies in ceria performance, showing that bioactivity is directly related to Ce3+ concentration. The antibacterial activity is influenced by the type, amount, and valence of the dopant, while cell proliferation is enhanced by doping at the lowest concentration.

Summary: In this study, a novel interlayer-assisted interfacial polymerization technique with the inclusion of graphene oxide (GO) was used to improve the permeability/selectivity trade-off, chlorine attack, and fouling issues of reverse osmosis membranes. The results showed that the PEI-interlayered thin film composite (iTFC) membrane exhibited higher pure water permeance and NaCl rejection compared to the conventional TFC (cTFC) membrane. The inclusion of 0.01 wt/v% GO further enhanced the performance of the iTFC membrane, producing a PEI-interlayered thin film nanocomposite (iTFN-10) membrane with greater pure water permeance without compromising rejection. The iTFN-10 membrane also demonstrated better antifouling and antibacterial properties compared to commercial membranes.

Summary: In this study, poly(citric acid)-grafted graphene oxide (PGO) was incorporated into single-layer hollow fiber (SLHF) and dual-layer hollow fiber (DLHF) membranes to improve their antifouling properties during water treatment. The optimized PGO loading of 0.7 wt% in SLHF membrane resulted in higher water permeability and bovine serum albumin rejection compared to the neat membrane. Similarly, introducing 0.7 wt% PGO only to the outer layer of DLHF membrane improved its antifouling properties and increased the rejection rate of bovine serum albumin to 97.7%.
