    Eco-friendly reactor mimics lightning to produce ammonia from air and water

    A plasma electrochemical reactor developed by Chris Li’s team can convert nitrogen in the air into ammonia without producing carbon dioxide emissions. Credit: Douglas Levere/University at Buffalo There’s a good chance you owe your existence to the Haber-Bosch process. This industrial chemical reaction between hydrogen and nitrogen produces ammonia, a key ingredient in the synthetic fertilizers that provide much of…

    Transition to electric vehicles could create unwanted air pollution hotspots in China and India

    Credit: Princeton University, Bumper DeJesus Electric vehicles are a cornerstone of the global energy transition, but a new Princeton University-led study finds that refining critical minerals needed for electric vehicle batteries could create pollution hotspots near manufacturing sites. It has been proven that there is. Researchers focused on China and India and found that if these countries fully domesticated their…
