Quinoline is a typical nitrogenous heterocyclic compound, which carcinogenic, teratogenic, and mutagenic to organisms, its wastewater difficult biodegrade directly. The bipolar electro-Fenton process was employed treat quinoline solution. process/reaction conditions were optimized through the single factor experiment. degradation kinetics of chemical oxygen demand (COD) analyzed. To get mechani...

The pronounced ability of water to form a hyperdense hydrogen (H)-bond network among itself is at the heart of its exceptional properties. Due to the unique H-bonding capability and amphoteric nature, water is not only a passive medium, but also behaves as an active participant in many chemical and biological reactions. Here, we reveal the catalytic role of a short water wire, composed of two (...

A facile self-assembly growth route assisted by surfactant has been developed to synthesize tris(8-hydroxyquinoline)aluminium (Alq(3)) nanorods with regular hexagonal shape and good crystallinity, which exhibit field-emission characteristics with a very low turn-on field of ca. 3.1 V microm(-1) and a high field-enhancement factor of ca. 1300.

[graph: see text] 8-Hydroxyquinoline benzoates were developed as a new set of 8-HQ derivatives for highly sensitive fluorescent chemosensors for transition metal ions. A prominent fluorescence enhancement was found in the presence of transition metal ions such as Hg2+ and Cu2+, and this was suggested to result from the suppression of radiationless transitions from the npi state in the chemosens...

8-Hydroxyquinoline-based ligands with extended conjugated fluorophores were designed to provide turn-on and ratiometric signal output optimized for use in fluorescence-based sensor arrays, where the changes in blue and green channels of the RGB signal are used to distinguish between cationic analytes.

Galactose-1-P uridylyltransferase purified from Escherichia coli cells grown in enriched medium contains approximately 1.2 mol of tightly bound zinc/mol of subunits as well as variable amounts of iron, up to 0.7 mol/mol of subunits, and no detectable Ca, Cd, Cu, Mo, Ni, Co, Mn, As, Pb, or Se. The chelators, 1,10-phenanthroline, 8-hydroxyquinoline, 8-hydroxyquinoline sulfonate, and 2,2'-bipyridy...

The conventional in vitro assays for genotoxicity assessment of chemicals are characterised by a high false-positive rate, thus failing to correctly predict their in vivo genotoxic effects. This study aimed to identify the cellular mechanisms induced by the false-positive genotoxins quercetin, 8-Hydroxyquinoline and 17-beta oestradiol in comparison to true genotoxins and non-genotoxins, by comb...
