US missile and space propulsion company Aerojet has completed hot-fire testing of a cryogenic oxygen and methane reaction control engine (RCE). The engine is being developed under NASA's propulsion ...

Researchers report the catalysis of a highly specific chemical reaction where oxygen from the air is one ingredient and the other, an organic molecule, is selectively 'oxidized'. A simple manganese ...

(a) Schematic in a solid oxide electrolyzer; (b) cross-sectional images of CMW@GDC/LSM/YSZ/NiO-YSZ solid oxide electrolyzer. The electrochemical oxidative coupling of ...

Methane emissions are strongly reduced in lakes with anoxic bottom waters. But – contrary to what has previously been assumed – methane removal is not always due to archaea or anaerobic bacteria. A ...

NASA’s decision to drop the development of liquid oxygen-and-methane-fueled engines from its Crew Exploration Vehicle (CEV) program is viewed as an opportunity lost by proponents of the clean-burning ...
