Per-and polyfluoroalkyl substances (PFAS), a large class of synthesized chemicals, are persistent in nature and generally recalcitrant to conventional chemical biological treatment. Adsorption is considered an economical practical method for PFAS Layered double hydroxides (LDHs) represent promising mineral-based adsorbents removal because the highly positive charge their structural layers. In t...

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...

The gene encoding the tetrameric malate dehydrogenase (MDH) in a thermophilic Bacillus species (BI) has been cloned in an Escherichia coli plasmid. The nucleotide sequence of the gene, the first to be elucidated for a tetrameric MDH, shows the MDH subunit to contain 312 amino acids and have a molecular mass of 33648 Da, which confirms the experimentally determined value of about 35 kDa. Like th...

Highly ordered transparent self-supporting films of layered double hydroxides (LDHs) with a size of the order of cm2 have been obtained by a simple method; the chemical composition of both the layers and interlayers can be readily tuned, as demonstrated by the preparation of [ZnAl-NO3] LDH, [NiAl-NO3] LDH and [Tb(EDTA)]- intercalated-ZnAl LDH films.

Mg-Al layered double hydroxides (LDHs) were applied to soils for controlling phosphorus (P) loss. The subsequent slow-release of immobilized P in LDHs-soil system is crucial its bioavailability crops. Saturated column experiments conducted investigate the influence carbonate and flow interruption (FI) on release retention phosphate results compared those obtained under bicarbonate or continuous...

Layered double hydroxides (LDHs) are a family of layer materials that receive heightened attention. Herein a ternary NiFeMn-LDH is investigated with superior oxygen evolution activity, which is attributed to the Mn(4+) doping in the intralayer, which modifies the electronic structure and improves the conductivity of the electrocatalyst.

Emerging contaminants (ECs) are a group of anthropogenic organic pollutants known to have host adverse environmental and health implications. The removal such from aqueous environments ensure water is quality fit for reuse therefore highly important gaining considerable interest. Whilst there multiple approaches used EC remediation matrices, sorption using layered double hydroxides (LDHs) has b...

This work first transformed hazardous aluminum waste into low-cost MgAl−layered double hydroxide@ANA zeolite (LDHs@ANA) composite for dye wastewater adsorption, which was meaningful recovery and pollution control. Based on this strategy, the Al(OH)3 extracted from secondary dross (a in industry) used as an source to synthesize LDHs@ANA composite, had more excellent adsorption capacity methylene...
