Generation and Detection of Reactive Oxygen Species in Photocatalysis.
Chemical Reviews, 2017The detection methods and generation mechanisms of the intrinsic reactive oxygen species (ROS), i.e., superoxide anion radical (•O2-), hydrogen peroxide (H2O2), singlet oxygen (1O2), and hydroxyl radical (•OH) in photocatalysis, were surveyed ...

Understanding of Oxygen Redox in the Oxygen Evolution Reaction
Advances in Materials, 2022The electron‐transfer process during the oxygen evolution reaction (OER) often either proceeds solely via a metal redox chemistry (adsorbate evolution mechanism (AEM), with metal bands around the Fermi level) or an oxygen redox chemistry (lattice oxygen ...

Oxygen transport— the oxygen delivery controversy
Intensive Care Medicine, 2004Most cellular activities require energy in the form of oxygen, primarily obtained from the degradation of adenosine triphosphate (ATP) and other high-energy compounds. Oxygen must be present in sufficient amounts in the mitochondria to maintain effective concentrations of ATP in the electron transport system.

Oxygen therapy and oxygen toxicity
Annals of Emergency Medicine, 1983When oxygen therapy is warranted, the minimum effective dose generally should be given. Hypoxemic patients who have normal baseline ABG may be treated initially with an intermediate to high FiO2 in the range of 35% to 100%, depending on the severity of the respiratory distress. The majority of patients with exacerbations of COPD who are not in extremis

Reactive oxygen species homeostasis and signalling during drought and salinity stresses.
Plant, Cell and Environment, 2010Water deficit and salinity, especially under high light intensity or in combination with other stresses, disrupt photosynthesis and increase photorespiration, altering the normal homeostasis of cells and cause an increased production of reactive oxygen ...

Design of electrocatalysts for oxygen- and hydrogen-involving energy conversion reactions.
Chemical Society Reviews, 2015A fundamental change has been achieved in understanding surface electrochemistry due to the profound knowledge of the nature of electrocatalytic processes accumulated over the past several decades and to the recent technological advances in spectroscopy ...

Reactive Oxygen Species (ROS)-Based Nanomedicine.
Chemical Reviews, 2019Reactive oxygen species (ROS) play an essential role in regulating various physiological functions of living organisms. The intrinsic biochemical properties of ROS, which underlie the mechanisms necessary for the growth, fitness, or aging of living ...

Oxygen-derived free radicals in postischemic tissue injury.
New England Journal of Medicine, 1985It is now clear that oxygen-derived free radicals play an important part in several models of experimentally induced reperfusion injury. Although there are certainly multiple components to clinical ischemic and reperfusion injury, it appears likely that ...
