Simultaneous removal of typical flotation reagent 8-hydroxyquinoline and Cr(VI) through heterogeneous Fenton-like processes mediated by polydopamine functionalized ATP supported nZVI
(Elsevier, 2022)
The heavy metal and organic pollution caused by mining activities keep attracting attention, thus an economic and efficient treatment for combined pollution is pressing. In this study, the simultaneous removal performance ...
Stereoselective Construction of Fluorinated Quaternary Stereogenic Centers via an Organocatalytic Asymmetric exo-Selective Diels-Alder Reaction in the Presence of Water
(USA : American Chemical Society, 2022)
A catalytic, asymmetric Diels-Alder reaction of α-fluoro α,β-unsaturated aldehydes and cyclopentadiene was developed using diarylprolinol silyl ether as an organocatalyst. The reaction proceeds in toluene with trifluoroacetic ...
Nanocomposite co-catalysts, based on smectite and biowaste-derived carbon, as peroxymonosulfate activators in degradation of tartrazine
(Elsevier, 2022)
Chitosan (Ch)-derived from biowaste along with smectite, an abundant clay mineral, were used in a low-cost and eco-friendly synthesis of a new type of catalyst. Nanocomposite catalysts constituted of Co supported on smectite ...
Batch and column adsorption of cations, oxyanions and dyes on a magnetite modified cellulose-based membrane
(Springer, 2020)
Abstract: An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; ...
Degradation of novel mineral flotation reagent 8-hydroxyquinoline by superparamagnetic immobilized laccase: Effect, mechanism and toxicity evaluation
(Elsevier, 2022)
The environmental impact of the mining industry requires efficient and eco-friendly technologies to mitigate the presence of mineral flotation reagents (MFRs) in mineral processing wastewater (MPW) prior to their discharge ...
Bacterial nanocellulose as green support of platinum nanoparticles for effective methanol oxidation
(Elsevier BV, 2022)
Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for ...
Cysteine and cerium as green corrosion inhibitors for AA7049: Mixture vs. complexation
(Elsevier, 2022)
In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures ...
Aspergillus welwitschiae inulinase enzyme cocktails obtained on agro-material inducers for the purpose of fructooligosaccharides production
(Elsevier, 2022)
Production of fructooligosaccharides (FOS) is a trending topic due to their prebiotic effect becoming increasingly important for the modern human diet. The most suitable process for FOS production is the one using fungal ...
Synthesis, characterization and in vitro evaluation of divalent ion release from stable NiFe2O4, ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 nanoparticles
(Elsevier, 2020)
A simple organic-phase synthesis process was used to produce bare NiFe2O4 and ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 ferrite nanoparticles. X-ray powder diffractograms for all investigated powders show characteristic peaks ...
Characterization of the starch surface binding site on Bacillus paralicheniformis α-amylase
(Elsevier, 2020)
α-Amylase from Bacillus paralicheniformis (BliAmy), belonging to GH13_5 subfamily of glycoside hydrolases, was proven to be a highly efficient raw starch digesting enzyme. The ability of some α-amylases to hydrolyze raw ...
