Flow Cytometry of Oxygen and Oxygen-Related Cellular Stress
Oxygen, 2023 Reactive oxygen species (ROS) are unstable and highly reactive molecular forms that play physiological roles in cell signaling and immune defense. However, when ROS generation is not properly balanced by antioxidant defenses, a pathological condition ...

Accounts of Chemical Research, 2018 Work on the electronic structures of metal-oxo complexes began in Copenhagen over 50 years ago. This work led to the prediction that tetragonal multiply bonded transition metal-oxos would not be stable beyond the iron-ruthenium-osmium oxo wall in the periodic table and that triply bonded metal-oxos could not be protonated, even in the strongest ...
