Reactive oxygen species and redox compartmentalization
Frontiers in Physiology, 2014 Reactive oxygen species (ROS) formation and signaling are of major importance and regulate a number of processes in physiological conditions. A disruption in redox status regulation, however, has been associated with numerous pathological conditions.

Redox signaling in acute oxygen sensing
Redox Biology, 2017 Acute oxygen (O2) sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB) is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ion channels.

Deactivation of redox mediators in lithium-oxygen batteries by singlet oxygen
Nature Communications, 2019 Redox mediators can enhance redox reactions in Li-O2 batteries; however, their gradual degradation remains unclear. Here the authors show that organic redox mediators are decomposed by singlet oxygen formed during cycling, indicating a strategy for the ...

Redox and low-oxygen stress: signal integration and interplay [PDF]
Plant Physiology, 2021 AbstractPlants are aerobic organisms relying on oxygen to serve their energy needs. The amount of oxygen available to sustain plant growth can vary significantly due to environmental constraints or developmental programs. In particular, flooding stress, which negatively impacts crop productivity, is characterized by a decline in oxygen availability ...

The role of redox changes in oxygen sensing [PDF]
Respiratory Physiology & Neurobiology, 2010 The specialized oxygen-sensing tissues include the carotid body and arterial smooth muscle cells in the pulmonary artery (PA) and ductus arteriosus (DA). We discuss the evidence that changes in oxygen tension are sensed through changes in redox status. "Redox" changes imply the giving or accepting of electrons.

Enhanced Cycling Stability in the Anion Redox Material P3‐Type Zn‐Substituted Sodium Manganese Oxide
ChemElectroChem, 2022 Sodium layered oxides showing oxygen redox activity are promising positive electrodes for sodium‐ion batteries (SIBs). However, structural degradation typically results in limited reversibility of the oxygen redox activity.

Empowering higher energy sodium‐ion battery cathode by oxygen chemistry
Interdisciplinary Materials, 2023 Sodium (Na) ion batteries (SIBs) promise low‐cost energy storage systems but are still restricted by insufficient energy density. Introducing oxygen (O) redox into the design of the Na‐storage cathode is presently considered an effective avenue to ...
