The energy-efficient extraction of oxygen directly from air remains a significant technological challenge. Anion-exchange membranes (AEMs) play a critical role in electrochemical systems due to their ...

A membrane electrode assembly (MEA) cell enables H 2 O 2 electrosynthesis via the two-electron oxygen reduction reaction. Single-membrane MEA, double-membrane solid-electrolyte MEA and membrane-free ...

Electrospray ionization mass spectrometry in the negative ion mode, ESI(-)-MS, was used to investigate the iodide-catalyzed decomposition of H2O2 in aqueous medium. ESI(-)-MS monitoring revealed the ...

Life in aerobic environments inevitably generates reactive oxygen species (ROS), which damage proteins and other cellular components, often irreversibly. Cells must degrade these potentially harmful, ...

Mitochondrial reactive oxygen species (ROS) have emerged as an important mechanism of disease and redox signaling in the cardiovascular system. Under basal or pathological conditions, electron leakage ...

Molecular oxygen (O 2) is the second most abundant gas in the Earth’s atmosphere, but in many natural environments, its concentration is reduced to low or even undetectable levels. Although low-oxygen ...
