Summary: In this study, polystyrene grafted hollow layered double hydroxides (NiCo-LDH@PS) were prepared and used as solid-phase micro-extraction (SPME) coating for the rapid detection of polycyclic aromatic hydrocarbons (PAHs) in combination with high performance liquid chromatography (HPLC). The NiCo-LDH@PS-coated SPME fiber showed enhanced adsorption capacity for seven PAHs and required only a small amount of adsorbent. The study demonstrated the great application potential of the hollow core-shell structured NiCo-LDH@PS as an SPME composite coating in adsorption and separation field.

Summary: This study presents a facile method for synthesizing ultrathin CoFe-based LDHs and reveals their high performance in OER. The Co site is identified as the main active center, and the doping of Fe accelerates the charge-transfer process. Surface Co sites are found to be the active centers for OER, while excessive subsurface Fe doping weakens OH* adsorption and increases the energy barrier of the rate-determining step.

Summary: In this study, manganese cobalt layered double hydroxide (MnCo-LDH) was incorporated into sulfur-doped NiCo-LDH (S-NiCo-LDH) on a nickel foam (NF) substrate via a hydrothermal process. The resulting composite exhibited a favorable morphology with high specific surface area and well-established pore structure, leading to a specific capacitance of 1581.3 F/g. When incorporated into a battery super-capacitor hybrid, the MnCo-LDH/S-NiCo-LDH composite demonstrated a wide potential window, high energy density, and excellent cyclic stability.

Summary: This study presents a simple and effective method for stabilizing nickel and ruthenium single atoms by creating vacancies on carbon nanotubes or TiO2, leading to the preparation of ultra-dispersed catalysts. The research demonstrates that catalysts supported on TiO2 are more active than those on carbon nanotubes, and nickel and ruthenium single atoms exhibit different product selectivity in the CO2 hydrogenation reaction.

Summary: This study reports on the preparation of organic-inorganic nanophases based on N-acetyl-L-cysteine (NAC) intercalation into zinc-aluminum and magnesium-aluminum layered double hydroxides (LDH). The synthesized hybrid materials were characterized and it was found that the zinc-aluminum LDH showed good crystallinity and a high loading capacity for NAC. However, NAC intercalation into magnesium-aluminum LDH was unsuccessful. In vitro drug delivery studies showed that the zinc-aluminum LDH was able to release NAC through a slow diffusion-controlled ion exchange process.

Summary: The study investigates the optical properties of sulforhodamine B hosted in surfactant-modified layered double hydroxide, examining the effects of different spacers on the luminescence of the optically active molecules. It demonstrates that intercalation of spacers allows for adjustment of distance between LDH sheets based on the size of the luminescent molecule guest, and identifies the surfactant with n = 11 as providing the best performance in terms of optical properties. The use of computational approaches and silicon composite films with LDH loadings further reveal insights into the distribution and effects of different alkyl chain lengths on the luminescent molecule within the LDH interlayer.
