> "Liquid metals allow us to move the chemical elements around in a more dynamic way that gets everything to the interface and enables more efficient reactions, ideal for catalysis," Daeneke said. "Copper and gallium separately had both been discounted as famously bad catalysts for ammonia production, yet together they do the job extremely well."
