Bioactive Iridium Nanoclusters with Glutathione Depletion Ability for Enhanced Sonodynamic‐Triggered Ferroptosis‐Like Cancer Cell Death

Advances in Materials, 2022
Ferroptosis is a regulated form of necrotic cell death that involves the accumulation of lipid peroxide (LPO) species in an iron‐ and reactive oxygen species (ROS)‐dependent manner.

Progress of Heterogeneous Iridium-Based Water Oxidation Catalysts.

ACS Nano, 2022
The water oxidation reaction (or oxygen evolution reaction, OER) plays a critical role in green hydrogen production via water splitting, electrochemical CO2 reduction, and nitrogen fixation. The four-electron and four-proton transfer OER process involves

Iridium

ACM SIGGRAPH 2016 VR Village, 2016
Compelling virtual reality experiences require high quality imagery as well as head motion with six degrees of freedom. Most existing systems limit the motion of the viewer (prerecorded fixed position 360 video panoramas), or are limited in realism, e.g. video game quality graphics rendered in real-time on low powered devices. We propose a solution for

Atomically dispersed hexavalent iridium oxide from MnO2 reduction for oxygen evolution catalysis

Science
Hexavalent iridium (IrVI) oxide is predicted to be more active and stable than any other iridium oxide for the oxygen evolution reaction in acid; however, its experimental realization remains challenging.
