Simultaneously Detection of Pb2+ and Hg2+ Using Electrochemically Reduced Graphene Oxide

International Journal of Electrochemical Science, 2018
In this work, graphene oxide (GO) was electrochemically reduced on the surface of glassy carbon electrodes (GCE) to fabricate a sensitive sensor for rapidly simultaneous determination of lead(II) and mercury (II) in water.

Heavy metal suicide [PDF]

American Journal of Physiology-Renal Physiology, 2017
In acute kidney injury (AKI), the majority of dying tubular cells succumbs to an iron-dependent form of regulated necrosis, referred to as ferroptosis. Ferroptosis is essentially mediated by iron-catalyzed lipid peroxidation upon GPX4 dysfunction. Heme oxygenase 1 (HO-1) is a master regulator of intracellular free iron due to the conversion of heme to ...

Sustainable treatment of nitrate-containing wastewater by an autotrophic hydrogen-oxidizing bacterium

Environmental Science and Ecotechnology, 2022
Bacteria are key denitrifiers in the reduction of nitrate (NO3−-N), which is a contaminant in wastewater treatment plants (WWTPs). They can also produce carbon dioxide (CO2) and nitrous oxide (N2O).
