Summary: The powdered layered double hydroxide (LDH) synthesized by hydrothermal coprecipitation was compounded with sodium alginate to form microspheres (LDH-AL). The characterizations of the LDH-AL show that the microspheres were successfully prepared. The immobilization experiments of hexavalent chromium (Cr(VI)) demonstrated the effectiveness of LDH-AL microspheres in the immobilization of Cr(VI) in soil.

Summary: By taking advantage of Ni2+ etching on Co-ZIF-L, a leaf-like NiCo layered double hydroxide (NiCo-LDH) with rough surface was prepared and used as the structure template for the synthesis of a two-dimensional core-shell NiCo-LDH/ZnIn2S4 composite. The tight interfacial contact and enhanced contact area between NiCo-LDH and ZnIn2S4 (ZIS) enable efficient electron transfer, addressing the fast photoinduced electron and hole recombination issue of ZIS. Consequently, the optimized NiCo-LDH content in the NiCoLDH/ZIS composite exhibits a high photocatalytic Cr(VI) reduction efficiency, capable of reducing 30 mg/L Cr(VI) within 3 min under visible light, which makes it a promising photocatalyst for Cr(VI) removal in polluted water.

Summary: This study reported the development of a series of new organically functionalized layered double hydroxide (LDH) adsorbents for the removal of per- and polyfluoroalkyl substances (PFAS) from contaminated water, with a specific focus on perfluorooctanoic acid (PFOA). The organically functionalized LDHs showed efficient PFOA adsorption by combining strong electrostatic and hydrophobic interactions. The adsorption kinetics and capacities were found to be higher for the organically functionalized LDHs compared to the unmodified LDH. Additionally, the organically functionalized LDHs exhibited improved performance under various water chemistry conditions and remained effective after repeated adsorption-regeneration cycles. This work suggests that organically functionalized LDHs hold great promise for the treatment of PFAS-contaminated water.

Summary: In this study, the surface charge density of NiFe LDH was tuned to improve the adsorption performance of Cr(VI) by nearly 150% through changing the iron valence. The increase in hydroxyl groups and charge density on the NiFe LDH surface was mainly attributed to the topological chemical transition. The adsorption of Cr(VI) onto Fe2+-NiFe LDH was highly pH-dependent and the main removal mechanisms involved electrostatic attraction, interlayer anion exchange, and adsorption-coupled reduction.

Summary: This study investigated the performance of two types of LDH materials for the removal of PFAS, finding that Zn-Al LDH showed higher efficiency and better adsorption capacity for PFOA compared to Mg-Al LDH. The presence of natural organic matter had minimal impact on PFOA removal by Zn-Al LDH, while sulfate severely inhibited PFOA adsorption, suggesting that electrostatic interactions may play a primary role in the adsorption mechanism onto LDHs for PFAS removal.

Summary: The exploration of highly efficient electrochemical water splitting catalysts has attracted significant interest. Layered double hydroxides (LDHs) have been shown to be one of the most efficient materials for oxygen evolution reaction (OER), but they still suffer from low conductivity and sluggish kinetics for hydrogen evolution reaction (HER), which limits the overall water splitting efficiency. To address this issue, various approaches including doping regulation, intercalation tuning, and defect engineering have been developed. In recent studies, the hybridization of LDHs with other two-dimensional materials has been explored to enhance both OER efficiency and HER activity.

Summary: This review focuses on versatile biomaterials based on nanocomposites for drug delivery and tissue engineering. Layered hydroxides can intercalate bioactive species and hold metal cations, providing elevated loading capacity and modified release profiles. They also exhibit beneficial characteristics in tissue integration and collagen formation. The association between biocompatible polymers and layered hydroxides produces multifunctional nanocomposites with stimuli-responsiveness and appropriate mechanical properties, enabling fine-tuning of drug release. Studies have shown the higher performance of these composites compared to the hybrid or free drug.

Summary: This study describes a method for fabricating stable and reproducible large-area surface-enhanced Raman scattering (SERS) substrates based on the assembly of pre-synthesized gold nanoparticles on reconstructed poly(styrene-block-2-vinylpyridine) (PS-b-P2VP) films. The results show that the annealing treatment and the molecular weight of the copolymers strongly influence the dispersion of nanoparticles and the SERS enhancements. Water and ethanol swelling of the micelles allow for high uniformity of nanoparticle deposition, while more efficient SERS enhancement is observed in the nanocomposites treated with toluene/THF vapor annealing and thermal annealing.

Summary: A biosensor was developed for directly detecting human immunoglobulin G (IgG) and adenosine triphosphate (ATP) using gold nanoparticles/polystyrene-b-poly(2-vinylpyridine) (AuNP/PS-b-P2VP) nanocomposites. The substrates were functionalized with carboxylic acid groups to bind anti-IgG and anti-ATP and detect IgG and ATP. SEM images showed gold nanoparticles adsorbed onto a porous thin film. UV-VIS and SERS were used to characterize substrate functionalization and antibody-target interaction. PCA discriminated between samples before and after affinity tests. The biosensor was sensitive to IgG concentrations with a limit of detection of 1 μg/mL.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
