Rechargeable zinc air batteries (RZABs), which repeatedly store and release charges through the oxygen evolution reaction (OER) reduction (ORR) using electrocatalysts, are considered a promising energy storage system owing to their low cost safety. Controlling chemical structure morphology of multifunctional electrocatalysts is crucial for improving electrocatalytic activities stabilities high ...

Layered double hydroxides (LDHs) are attractive electrode materials for supercapacitors due to their high theoretical capacitances and adjustable compositions, but also subjected intrinsic poor electrical conductivity easy structure collapse properties. To resolve these intractable issues, LDHs usually integrated with specific surface areas (SSAs) matrixes. Herein, [email protected] nanoflakes ...

Nickel-based layered double hydroxides (LDHs) are promising electrode materials in the fields of energy storage (supercapacitors) and conversion (urea oxidation). The rational construction atomic electronic structure is crucial for nickel-based LDHs to realize their satisfactory electrochemical performance.

Small interfering RNAs (siRNAs) are a potentially powerful new class of pharmaceutical drugs for many disease. However, the delivery of unprotected siRNAs is ineffective due to their susceptibility to degradation by ubiquitous nucleases under physiological conditions. Layered double hydroxide nanoparticles (LDHs) have been found to be efficient carriers of anionic drugs and nucleic acids. Our p...

We demonstrated that analyzing the formed gels containing exfoliated nitrate or glycine intercalated layered double hydroxide (LDH) nanosheets in formamide using X-ray diffraction is a simple and reliable method for determining the delamination degree of LDHs in formamide, which shows many advantages compared to the common characterization technologies.

The synthesis of the copper-poor and aluminum-rich layered double hydroxides (LDHs) CuAl4 type was optimized in detail this work, by applying an intense mechanochemical treatment to activate gibbsite starting reagent. phase-pure forms these LDHs were prepared for first time; using copper nitrate perchlorate salts during syntheses turned out be key avoiding formation hydroxide sideproducts. Base...

Nickel-iron layered double hydroxides (Ni-Fe LDHs) consist of stacked Fe3+-doped positively charged Ni-hydroxide layers containing charge-balancing anions and water molecules between the layers. Although Ni-Fe LDHs are highly active in oxygen evolution reaction (OER) under alkaline conditions, their poor operational stability remains an issue. Herein, based on density functional theory calculat...

The chemotherapy for tuberculosis (TB) is complicated by its long-term treatment, its frequent drug dosing, and the adverse effects of anti-TB drugs. In this study, we have developed two nanocomposites (A and B) by intercalating the anti-TB drug isoniazid (INH) into Zn/Al-layered double hydroxides. The average size of the nanocomposites was found to bê164 nm. The efficacy of the Zn/Al-layered d...
