Carbon Energy, EarlyView.A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Freeway Performance MeasurementSystem (PeMs), PeMS 7.0 [PDF]
, 2007 PeMS 7.0 is the latest of eight task orders devoted to research, development, andmaintenance of the PeMS system (there was one mid-year task order, PeMS 6.5).PeMS collects, processes, stores, and makes available online data from nine Caltransdistricts (D3-8, 10-12). The data are obtained from 23,871 loops1, grouped into 9,306 vehicle detector stations (

Carbon Energy, EarlyView.Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Analysis of PEM electrolyzers [PDF]
, 1998 Hydrogen and oxygen can be produced using a PEM electrolyzer. A PEM electrolyzer operates like a fuel cell in reverse. On the anode side of the electrolyzer, electrons are removed from water to form protons and oxygen molecules. The protons are then transported across the membrane. The protons then rejoin with electrons to form hydrogen molecules.

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants
Chemie Ingenieur Technik, EarlyView.The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.
