Strontium-Doped Perovskites Rival Platinum Catalysts for Treating NOx in Simulated Diesel Exhaust -- Kim et al. 327 (5973): 1624 -- Science: "There is a recognized need to lower greenhouse gas emissions from mobile sources in order to address concerns regarding global climate change. Diesel engines offer superior fuel efficiency and greenhouse gas reduction potential; however, one of the technical obstacles to their broad implementation is the requirement for a lean nitrogen oxide (NOx) (NO + NO2) after-treatment system, a key contributor to the high cost premium for diesel vehicles."
