Four-Electron Oxygen Reduction by Tetrathiafulvalene [PDF]

Journal of the American Chemical Society, 2011
The four-electron reduction of oxygen by tetrathiafulvalene (TTF) in acidified 1,2-dichloroethane and at the acidified water/1,2-dichloroethane interface has been observed. Spectroscopy and ion transfer voltammetry results suggest that the reaction proceeds by the fast protonation of TTF followed by the 4-electron reduction of oxygen to form water ...

Year-round N2O production by benthic NOx reduction in a monomictic south-alpine lake [PDF]

, 2013
Nitrous oxide (N2O) is a potent greenhouse gas, generated through microbial nitrogen (N) turnover processes, such as nitrification, nitrifier denitrification, and denitrification.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Electrocatalytic Behavior of Pt/WO3 Composite Layers Formed Potentiodynamically on Tungsten Surfaces

International Journal of Electrochemical Science, 2017
The Pt/WO3 composites, in a form of thin layer on W support, were prepared by potentiodynamic polarization of either bare or oxide covered tungsten disc in hexachloroplatinic acid solutions. Both the Pt loading and the thickness of WO3 interlayer between

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
