Herein, a fiber-supported iron-based ionic liquid as type of fibrous catalyst has been developed for the synthesis bioactive 3,4-dihydropyrimidin-2-(1H)-ones (DHPMs) via three-component Biginelli reactions in cleaner manner. The described was obtained from commercially available polyetheretherketone (PEEK) fiber by postfunctionalization processes and characterized analyzed detail means diversified technologies. Furthermore, liquids could mediate classical to proceed smoothly gain variety...

Abstract The new material polypyrrole/MoS 4 2− (MoS ‐Ppy), prepared by ion‐exchange of NO 3 ‐ ‐Ppy with MoS , displays high acid stability and excellent uptake for heavy metal ions such as Hg 2+ Ag + Cu Pb . different maximum adsorption capacities ( q m ) depend on the various binding modes arising from thiophilicity these ions. removals reach >99.6% within 5 min, highly toxic >98% removal achieves at 1 min. At strong limit, exceptional (Ag 725 mg g −1 places top materials removal....

The new material Polypyrrole–Mo3S13 (abbr. Mo3S13–Ppy) is a prepared by ion-exchange between Ppy-NO3 and (NH4)2Mo3S13. Mo3S13–Ppy was designed to exhibit strong selectivity for Ag+ highly toxic Hg2+ in mixtures with other ions. It displays an apparent ranking of > ≥ Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Pb2+. affinity confirmed extremely high distribution coefficients (Kd) (∼107 mL/g) remarkable removal efficiencies (>99.99%), resulting <1 ppb concentrations these Furthermore, achieved excellent...

We demonstrate a new material by intercalating Mo3 S132- into Mg/Al layered double hydroxide (abbr. S13 -LDH), exhibiting excellent capture capability for toxic Hg2+ and noble metal silver (Ag). The as-prepared -LDH displays ultra-high selectivity of Ag+ , Cu2+ in the presence various competitive ions, with order >Hg2+ >Cu2+ >Pb2+ ≥Co2+ Ni2+ Zn2+ Cd2+ . For extremely fast adsorption rates (≈90 % within 10 min, >99 1 h) are observed. Much high is present especially trace amounts (≈1 ppm),...

Oxygen-rich pyromellitic acidic anions (PMA4-) have been intercalated into MgAl-layered double hydroxides to fabricate the MgAl-PMA-LDH (abbr. PMA-LDH) composite exhibiting excellent adsorption performance toward uranium (U(VI)). Benefiting from large number of functional groups -COO-, PMA-LDH displays an extremely maximum U capacity (qUm) 352 mg g-1 and ultra-fast sorption rate, reaching uptakes ∼97% within 30 min >99% in 1 h at initial concentration (CU0) 113 ppm. Over a very wide pH range...

Numerical investigations were conducted to predict the performance of a transonic axial compressor rotor with circumferential groove casing treatment. The Notre Dame Transonic Axial Compressor (ND-TAC) was simulated at Tsinghua University an in-house computational fluid dynamics (CFD) code (NSAWET) for this work. Experimental data from ND-TAC used define geometry, boundary conditions, and sampling method numerical simulation. These efforts, combined several unique simulation approaches, such...

Co-immobilized bienzyme biocatalysts are attracting increasing interest in the field of wastewater treatment due to their widespread application. In this study, we successfully prepared a co-immobilized biocatalyst by immobilizing horseradish peroxidase (HRP) and glucose oxidase (GOD) on dopamine (DA) modified cellulose (Ce)-chitosan (Cs) composite beads via covalent binding, designated as Ce-Cs@DA/HRP-GOD beads, found that had good ability catalytically degrade acridine wastewater. SEM,...
