In a significant step towards improving the design of future catalysts and catalytic reactors, especially for microfluidic “lab-on-a-chip” devices, researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley, have successfully applied magnetic resonance imaging (MRI) to the study of gas-phase reactions on the microscale.
