Sorption is recognized as an effective and economical approach for the practical treatment of water contaminated with per- polyfluoroalkyl substances (PFAS). In this study, we reported development, characterization, evaluation a family new organically functionalized layered double hydroxide (LDH) adsorbents PFAS removal primary focus on perfluorooctanoic acid (PFOA). The organic functional grou...

BACKGROUND During the past few decades, the occurrence of superficial fungal infections has rapidly increased. As the fungal infections take longer time to get cured, concepts such as designing drugs with extended persistence and controlled release have gained attention. In this context, nanotechnology has been identified as the latest technological revolution which has opened up new pathways f...

CH₄ as the paramount ingredient of natural gas plays an eminent role in C1 chemistry. CH₄ catalytically converted to syngas is a significant route to transmute methane into high value-added chemicals. Moreover, the CO/CO₂ methanation reaction is one of the potent technologies for CO₂ valorization and the coal-derived natural gas production process. Due to the high thermal stability and high ext...

Layered double-hydroxide (LDH) minerals have recently attracted attention through their potential industrial application as fillers in mineral–polymer nanocomposite materials and, separately, as solid base catalysts to promote a range of reactions in an environmentally sound way. Little research has been undertaken on the crystal growth mechanism of LDHs using in situ methods. Recently, advance...

A series of transition metal sulphonato-Schiff base complexes were intercalated into Mg–Al layered-double hydroxides (LDHs). The obtained catalysts were characterized by FTIR, XRD, N2 sorption, SEM and elemental analysis, and then were used in the selective oxidation of glycerol (GLY) using 3% H2O2 as an oxidant. It was found that their catalytic performances were closely related to the loading...

The loading capacity and strategy of layered double hydroxides (LDHs) determine their suitability for drug delivery applications. In this study, two sizes MgAl-CO3 LDHs are converted into MgAl-NO3 MgAl-Cl by an acid-salt method. influence the size type interlayer anions on studied compared. Here, Methylene Orange (MO) served as anionic structure to capacity. Due strongest anion-exchange NO3− la...

Composite hydrogels were prepared that consisted of quasi-colloidal layered double hydroxide (LDH) nanoparticles and agarose via the electrophoretic method, starting from three different agarose concentrations of 0.5, 1, and 2 wt/v%. The composite hydrogel was identified to have a uniform distribution of LDH nanoparticles in agarose matrix. Microscopic studies revealed that the composite hydrog...

OBJECTIVE Layered double hydroxide (LDH) nanoparticles have been studied as cellular delivery carriers for anionic anticancer agents. As MTX and 5-FU are clinically utilized anticancer drugs in combination therapy, we aimed to enhance the therapeutic performance with the help of LDH nanoparticles. METHOD Anticancer drugs, MTX and 5-FU, and their combination, were incorporated into LDH by reco...
