The research team led by Schneider; David Go, Rooney Family Associate Professor of Engineering in aerospace and mechanical engineering; and Jason Hicks, associate professor of chemical and biomolecular engineering, discovered that because the nitrogen molecules are activated by the plasma, the requirements on the metal catalysts are less stringent, allowing less expensive materials to be used throughout the process.

Nitrogen is not a greenhouse gas, but the increased pressure would have led to more frequent collisions between nitrogen molecules and greenhouse gases, causing them to absorb at more infrared wavelengths.
