Electric vehicle standardization across platforms, models and manufacturers. Swapping also requires many times more battery packs to be in the system. According to Department of Energy research conducted at Pacific Northwest National Laboratory, 84% of existing vehicles could be switched over to plug-in hybrids without requiring any new grid infrastructure. In terms of transportation, the net result would be a 27% total reduction in emissions of the greenhouse gases carbon dioxide, methane, and nitrous oxide, a 31% total reduction in nitrogen oxides, a slight reduction in nitrous oxide emissions, an increase in particulate matter emissions, the same sulfur dioxide emissions, and the
Nitrous-oxide reductase competent unit. The Cu center can undergo a one-electron redox change and hence has a function similar to that in the well-known aa-type cytochrome "c" oxidases () where it serves to receive an electron from soluble cytochromes "c". Acetylene is the most specific inhibitor of nitrous-oxide reductase. Other inhibitors include azide anion, thiocyanate, carbon monoxide, iodide, and cyanide. Nitrous-oxide reductase In enzymology, a nitrous oxide reductase also known as nitrogen:acceptor oxidoreductase (NO-forming) is an enzyme that catalyzes the final step in bacterial denitrification, the reduction of nitrous oxide to dinitrogen. It plays a critical role in preventing release of a
