Developing a high-performance anode design is important for low-cost proton-exchange membrane water electrolyzer (PEMWE). In this study, an iridium nickel oxide directly coated (IrNiOx electrode) high-efficient PEMWE reported. Five IrNiOx electrodes with different Ir-to-Ni ratios are developed using co-electrodeposition. The resulting contain thin layer on the carbon substrate. To develop incor...

Molten Oxide Electrolysis (MOE) is a promising and laboratory-proven in-situ resource utilization technology for generating oxygen from lunar regolith simulant. Prior to this work, iridium metal was the only demonstrated suitable inert anode material, but its use had been limited to laboratory-scale testing owing to its extraordinarily high density, hardness, and cost. In the current work, elec...

Potential cycling in the range from -0.2 to +1.2 V is used for the electrodeposition of hydrous iridium oxide films onto a screen-printed electrode from a saturated solution of alkaline iridium(III) solution. The iridium oxide redox couple shows a stable and obvious reversible redox, with the formal potential being pH dependent in the range 1-14. The properties, stability and electrochemical pr...

We show results of the Lyon-Fedder-Mobarry (LFM) global MHD simulations of an event previously examined using Iridium spacecraft observations as well as DMSP and IMAGE FUV data. The event is chosen for the steady northward IMF sustained over a three-hour period during 16 July 2000. The Iridium observations showed very weak or absent Region 2 currents in the ionosphere, which makes the event fav...

The reactions of water with a number of iridium(III) complexes relevant to the mechanism for catalytic methanol carbonylation are reported. The iridium acetyl, [Ir(CO)2I3(COMe)](-), reacts with water under mild conditions to release CO2 and CH4, rather than the expected acetic acid. Isotopic labeling and kinetic experiments are consistent with a mechanism involving nucleophilic attack by water ...

The objective of this study has been to compare treatment plans for patients treated with electronic brachytherapy (eBx) using the Axxent System as adjuvant therapy for early stage breast cancer with treatment plans prepared from the same CT image sets using an Ir-192 source. Patients were implanted with an appropriately sized Axxent balloon applicator based on tumor cavity size and shape. A CT...

introduction in this study, we aimed to calculate dose enhancement factor (def) for gold (au) and iron (fe) nanoparticles (nps) in brachytherapy and teletherapy, using monte carlo (mc) method. materials and methods in this study, a new algorithm was introduced to calculate dose enhancement by aunps and fenps for iridium-192 (ir-192) brachytherapy and cobalt-60 (co-60) teletherapy sources, using...
