NSLS-II scientist named DOE Office of Science Distinguished Fellow

Scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have garnered two out of five “Distinguished Scientists Fellow” awards announced today by the DOE’s Office of Science.

Theoretical physicist Sally Dawson, a world-leader in calculations aimed at describing the properties of the Higgs boson, and José Rodriguez, a renowned chemist exploring and developing catalysts for energy-related reactions, will each receive $1 million in funding over three years to pursue new research objectives within their respective fields.

José Rodriguez (NSLS-II)

For discoveries of the atomic basis of surface catalysis for the synthesis of sustainable fuels, and for significantly advancing in-situ methods of investigation using synchrotron light sources.”

Rodriguez will devote his funding to the development and construction of new tools for performing extremely rapid, time-resolved measurements to track the reaction mechanisms of catalytic processes as they occur under variable conditions—like those encountered during real-world reactions important to energy applications. These include processes on metal-oxide catalysts frequently used in the production of clean fuels and other “green” chemicals through hydrogenation of carbon monoxide and carbon dioxide, or the conversion of methane to hydrogen.

“At a microscopic level, the structure of a catalyst and the chemical environment around the active sites—where chemical bonds are broken and reformed as reactants transform into new products—change as a function of time, thus determining the reaction mechanism,” said Rodriguez. “We can learn a lot about the nature of the active sites under steady-state conditions, with no variations in temperature, pressure, and reaction rate. But to really understand the details of the reaction mechanism, we need ways to track what happens under transient or variable conditions. This funding will allow us to build new instrumentation that works with existing capabilities so we can study catalysts under variable conditions—and use what we learn to improve their performance.”
