On dithiothreitol (DTT) as a measure of oxidative potential for ambient particles: evidence for the importance of soluble ewline transition metals [PDF]
Atmospheric Chemistry and Physics, 2012 The rate of consumption of dithiothreitol (DTT) is increasingly used to measure the oxidative potential of particulate matter (PM), which has been linked to the adverse health effects of PM. While several quinones are known to be very reactive in the DTT

The Effect of Water on Quinone Redox Mediators in Non- aqueous Li-O2 Batteries [PDF]
arXiv, 2018 The parasitic reactions associated with reduced oxygen species and the difficulty in achieving the high theoretical capacity have been major issues plaguing development of practical non-aqueous Li-O2 batteries. We hereby address the above issues by exploring the synergistic effect of 2,5-di-tert-butyl-1,4- benzoquinone and H2O on the oxygen chemistry ...

Ir(III)-Naphthoquinone complex as a platform for photocatalytic activity
Journal of Photochemistry and Photobiology, 2022 Inspired by the primary events that take place in Photosystem II (PSII), we designed and synthesized a heteroleptic Ir(III) complex featuring an attached naphthoquinone (NQ) as an electron transfer (ET) auxiliary reminiscent of the plastoquinone electron

THz-Raman Identification of labile products in the system "phenol-semiquinone-quinone" [PDF]
arXiv, 2016 The paper presents the results of SERS studies of the dynamic behavior of "phenol-semiquinone-quinone" system. This system is a key part of chemiluminescent sensors for reactive oxygen species. The dynamics of the system seems to be very important in the processes that determine the secondary metabolism at the cellular level in molecular biology.
