In situ observation of reactive oxygen species forming on oxygen-evolving iridium surfaces.

Water splitting performed in acidic media relies on the exceptional performance of iridium-based materials to catalyze the oxygen evolution reaction (OER). In the present work, we use in situ X-ray photoemission and absorption spectroscopy to resolve the long-standing debate about surface species present in iridium-based catalysts during the OER. We find that the surface of an initially metalli...

O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

Reactive oxygen species in iridium-based OER catalysts.

Tremendous effort has been devoted towards elucidating the fundamental reasons for the higher activity of hydrated amorphous IrIII/IV oxyhydroxides (IrO x ) in the oxygen evolution reaction (OER) in comparison with their crystalline counterpart, rutile-type IrO2, by focusing on the metal oxidation state. Here we demonstrate that, through an analogy to photosystem II, the nature of this reactive...

Effect of Reactive Oxygen Species on Germination and Lipid Proxidation in Sunflower Seeds

Reactive oxygen species cause to release of dormancy in many plants such as sunflower seeds. This study investigated in order to evaluation role of reactive oxygen species germination and lipid proxidation in sunflower seeds. This study was performed in two separate experiments, each in a completely randomized design with factorial design with four replications.  In both experiments, uses from ...
