Goran Jovanovic, professor of chemical engineering at Oregon State, was interested in finding ways to convert carbon dioxide into useful products using renewable energy. When the U.S. Department of Energy rejected a proposal in 2005, Jovanovic sent out an email to former Ph.D. students around the world, looking for potential collaborators. A copy of that email landed in the inbox of Thana Sornchamni, leading to an enduring and mutually beneficial partnership with PTT, Thailand's biggest industrial giant.
