Summary: In this study, a new metal-organic framework (MOF) modified TiO2 nanotubes (NTs) composite was prepared by a solvothermal method, which showed improved photoelectrochemical performance under visible light irradiation and could be used as a stable photoanode for photogenerated cathodic protection. Compared with single-component TiO2 photoanode, the MOF/TiO2 composite exhibited higher photogenerated current density, lower charge transfer resistance, and negatively shifted bias threshold, providing stable photogenerated cathodic protection for the electrode.

Summary: The long-term corrosion resistance of conventional micro-arc oxidation (MAO) coatings on magnesium alloy is limited by the inherent micro-scale pores. Zeolitic imidazolate framework-8 (ZIF-8) and zinc gluconate (ZnG) loaded ZIF-8 (ZnG@ZIF-8) were synthesized and incorporated into the MAO coating to enhance the corrosion resistance. The (ZIF-8 + ZnG@ZIF-8)/MAO composite coating showed significant improvement in corrosion protection compared to the blank MAO coating.

Summary: This work evaluates the electrochemical behavior and morphological characterization of a system consisting of a cerium conversion layer, a hybrid sol-gel coating, and the two coatings applied sequentially (duplex) for corrosion protection of WE43 Mg alloy. Different characterization techniques showed that the previous application of the conversion coating improved the surface coverage by the hybrid coating. Fitting impedance diagrams with electrical equivalent circuits allowed proposing a physical model for the coating, demonstrating its interaction with the porous Mg oxide/hydroxide layer. Self-healing properties of the duplex coating were also revealed.

Summary: Microcapsules containing Isophorone diisocyanate (IPDI) and terminal isocyanate prepolymer (CPU) were synthesized as active healing agents and mixed with epoxy resin to form a metal anti-corrosion coating with excellent self-healing properties. The encapsulation of CPU-IPDI in microcapsules using Diphenylmethane diisocyanate (MDI) as the shell was confirmed by spectroscopy. The size of the microcapsules decreased with the increase of the content of the stabilizing agent. The coating with microcapsules showed obvious healing and enhanced corrosion protection ability.

Summary: Graphene is a promising material for corrosion protection, but its tendency to agglomerate and the corrosion-promotion effect of its high electrical conductivity limit its application. This study prepared impermeable graphene using high-energy ball milling and encapsulated it with insulating poly(m-phenylenediamine) through non-covalent interaction. The encapsulated graphene showed good dispersibility and compatibility and effectively protected the steel substrate for up to 60 days when embedded in a composite coating.

Summary: Using nanomaterials to design and prepare photoanodes can improve photoelectrochemical and photocathodic protection performances. This study focuses on the correlation between the detailed nanostructure and performance of a ZnO/TiO2 composite for the PCP of nickel-coated magnesium alloy. By manipulating the hydrothermal reaction temperature, a morphologically tunable nano-ZnO semiconductor was obtained, and the optimum photoelectrochemical and PCP capacities were achieved. The enhanced performance was attributed to the morphological regulation of nano-ZnO and the formation of staggered gap heterojunction between ZnO and TiO2.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
