Summary: Intercalation of carboxylate into layered zinc hydroxides can be achieved directly at room temperature, resulting in crystalline, soluble, and functionalized materials. This direct synthesis method leads to high yields of exfoliated monolayer nanosheets, with high solubilities in alcohols and water. By altering the carboxylate ligand, functional groups suitable for post-synthetic modification or for detection by fluorescence are also introduced.

Summary: The rare-earth hydroxides LEu(x)Tb(1-x)Hs nanosheets were stably isolated in polyvinyl alcohol (PVA) hydrogels via a freeze-thaw method, which inhibited the energy transfer from Tb3+ to Eu3+ and the Eu3+ concentration quenching effect, resulting in independent photoluminescence emissions of Eu3+ and Tb3+ and corresponding multicolor photoluminescence.

Summary: We have successfully synthesized high-quality 2D rare-earth oxide (REO) single crystals with tailorable facets by designing a hard-soft-acid-base couple to control the orientation growth and crystal facets. This breakthrough provides a foundation for investigating facet-dependent properties and exploring various applications of 2D REO.

Summary: The exfoliation ability of nitrate based Mg-Al LDH into single or multilayer nanosheets is strongly influenced by nitrate anion orientation and layer charge. Superior exfoliation was observed for nitrate LDH compared to clays with carbonate, sulfate, chloride, or iodide as charge balancing anions, with an optimum composition for single nanosheet exfoliation at x≈0.25. The study also found that particles with platelet-like morphology exfoliated more effectively, suggesting that hydrothermal treatment may enhance exfoliation yields.

Summary: In this study, Mg-Al layered double oxides were modified by La2O3 to enhance the adsorption-photocatalytic degradation efficiency of tetracycline hydrochloride under solar-light induced conditions. The optimal La2O3 content of 4.35% in La/Mg-Al composite exhibited excellent removal efficiency and photocatalytic durability.

Summary: The discharge of toxic heavy metals is a serious threat to both human health and the environment. However, current water purification systems lack effective materials for the rapid, efficient, and cost-effective remediation of these toxic heavy metals. In this study, a new adsorbent called L-cysteine (Cys) intercalated Mg-Al layered double hydroxide (MgAl-LDH/Cys) was developed for the removal of Pb(II) and Cd(II). This material has a loose lamellar porous structure and, thanks to the intercalation of Cys, it has both increased diffusion of heavy metals and additional capture sites. As a result, MgAl-LDH/Cys exhibited significantly higher sorption capacity and faster sorption kinetics compared to pristine MgAl-LDH. These findings suggest that MgAl-LDH/Cys has great potential for practical applications in heavy metal remediation.

Summary: The study investigates the intrinsic ferromagnetism of 2D materials based on rare earth metal element GdGe2. Monolayer GdGe2 is found to be a ferromagnetic half-semiconductor with a large magnetic moment and an indirect band gap, while the AB-stacking bilayer GdGe2 shows promise as a high Curie temperature half-metal. Stacking order influences interlayer distance and magnetic coupling of multilayer GdGe2, with potential for modulation of electronic structure and magnetic order through interlayer stacking design.
