Summary: The composite LDHs film provides excellent initial protection to Mg-4Zn alloy, and during long-term immersion, corrosion products are deposited on both the bare alloy and the film, enhancing barrier and self-healing effects. Despite filiform corrosion on the substrate, the coated sample remains intact with only local pit corrosion after 18 days of immersion.

Summary: Layered double hydroxides (LDHs) have been synthesized with a simple and low-cost method to prepare ternary LDH MnFeZn-LDH. The MnFeZn-LDH-modified glassy carbon electrode (GCE) was used for the electrochemical analysis of flutamide (FLA), exhibiting better sensitivity (5.04 μA μM-1 cm-2) and selectivity. The electrode showed appreciable limit of detection with a linear range of 0.019-2735.79 μM. The MnFeZn-LDH demonstrated good electrochemical performances in terms of repeatability, reproducibility, and stability. The results highlight the potential of MnFeZn-LDH for FLA detection and its application in various fields.

Summary: CuFeCr ternary-layered double hydroxides were successfully prepared using the microwave hydrothermal method and showed excellent adsorption performance for removing hexavalent chromium ions from aqueous solutions. The material exhibited a larger specific surface area and reached a saturated adsorption capacity of 22.24 mg/g for Cr(VI) ions at pH=2, fitting well with the pseudo-secondorder kinetic model and Langmuir adsorption isotherm. This study demonstrates the potential of L-CuFeCr as a promising adsorbent for environmental remediation.

Summary: In this study, a NiCeCo-layered double hydroxide-chlorine-bridged compound was successfully synthesized and demonstrated excellent electrochemical performance in a binder-free electrode. The unique structure and complex assembly of the electrode resulted in remarkable capacitance and low internal resistance, allowing for high energy density in an all-solid-state supercapacitor when assembled with activated carbon electrodes. The supercapacitor enabled continuous operation of a multifunctional display for over three and a half hours.

Summary: This study compares the effective intercalation strategies of phytate onto Zn-Fe layered double hydroxide (LDH) through coprecipitation and anion exchange methods. The results show that coprecipitation method can achieve intercalation, while anion exchange method cannot. The adsorption behavior of phytate onto the LDH surface under different conditions follows the Langmuir isotherm equation and pseudo-second-order kinetic model.

Summary: Magnesium (Mg)-based alloys have shown promise as implants for orthopedics, but improving their corrosion resistance and biofunctions has remained a challenge. In this study, three transition metal-containing layered double hydroxides (LDHs) were prepared on Mg alloy, and their properties were compared. LDH-Mn exhibited the best corrosion resistance, LDH-Fe showed good cytocompatibility and antibacterial properties, and LDH-Co had high cytotoxicity. An optimized bilayer LDH coating enriched with Fe and Mn (LDH-MnFe) was designed, providing excellent anti-corrosion properties and multiple biofunctions (antibacterial, antitumor, and osteogenesis).
