The emission of greenhouse gases threatens the global environment, and scientists around the world are increasingly committed to addressing this issue. While many research groups focus on carbon dioxide (CO2) or methane (CH4) revalorization strategies, a team led by Dr. Josep Cornellà at the Max-Planck-Institut für Kohlenforschung has focused on a lesser-known gas that also contributes significantly to global warming: nitrous oxide (N2O), also known as "laughing gas."
