Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Effect of fuel dilution by CO2 on spherical diffusion flames in microgravity [PDF]

39th Aerospace Sciences Meeting and Exhibit, 2001
This paper presents the experimental results for expanding spherical diffusion flames in microgravity. The flames are fueled with ethylene diluted with various concentrations of CO2. A comparison is made between flames with pure ethylene and the diluted flames to test the effect of increased radiative heat loss predicted by the CO2 addition.
