In shifting from fossil fuels to renewable energy, a promising strategy is to convert the greenhouse gas, carbon dioxide (CO2), into useful liquid fuels and chemicals. Since copper (Cu) remains the sole element able to catalyze the reduction of CO2 to valuable products, significant effort has been devoted to developing Cu electrocatalysts with improved selectivity and activity. While information about Cu chemical states and particle structure under reaction conditions would help in these efforts, such “operando” experiments had previously been unfeasible,...

Two Kavli ENSI faculty have been elected members of the American Academy of Arts & Sciences.

"Founded in 1780, the American Academy of Arts and Sciences honors excellence and convenes leaders to examine new ideas, address issues of importance to the nation and the world, and advance the public good."

"For more than 240 years, the Academy has been electing and engaging exceptional individuals. This year’s election of 261 new members continues a tradition of recognizing accomplishments and leadership in academia,...

in acetogenic bacteria is used to reduce CO2 to acetyl coenzyme A (acetyl-CoA), a common biosynthetic intermediate, and eventually acetic acid. This WLP pathway for acetate synthesis consists of two separate branches, the methyl-branch and the carbonyl branch (Figure 1). In the carbonyl branch, CO2 is reduced to CO via the carbon monoxide dehydrogenase/acetyl-CoA synthase (CODH/ACS). In...

A new study with implications for atmospheric chemistry has answered some long-enduring questions about the chemical reactivity of an air pollutant molecule with aerosol, revealing the vital role played by the interface between water and gas. The results carry impacts for environmental and climate science, as well as human health.

Researchers from the University of California conducted the research, which provides a quantitative picture of the reactive uptake of dinitrogen pentoxide (N2O5) to aqueous aerosol. Their findings have been published in ...
