Decoding Reactive Structures

February 11, 2022

Palladium atoms in dilute Pd-in-Au alloys may form beautiful patterns in TEM images that are as mesmerizing as those colorful dots in the paintings of Georges Seurat. They are also excellent catalysts - but how to identify their most active ensembles in reaction conditions has been a very challenging task, not only because of the small size of the ensembles that may contain 1, 2 or 3 Pd atoms surrounded by Au atoms, but also because of their...

The Pd ensemble size in a Pd-Au catalyst plays a critical role in hydrogen dissociation

July 13, 2021

Selective hydrogenation—adding “just enough” hydrogen—is critical for a wide range of industrial processes including the manufacturing of polymers and pharmaceuticals. A catalyst can facilitate the supply of hydrogen atoms to a reaction by splitting hydrogen molecules and facilitating migration along the catalyst surface. But what determines how good a catalyst is at dissociating hydrogen? Researchers from Harvard University and UCLA joined forces to address this question, and found something surprising on the way, as described in a recent...

AVS Graduate Research Award for Chris O'Connor

October 29, 2020
Recent IMASC graduate Chris O'Connor has been recognized with a Graduate Research Award by AVS. The Graduate Research Awards were established in 1984 to recognize and encourage excellence in graduate studies in the sciences and technologies of interest to AVS. Each consists of a cash award, a certificate, and reimbursed travel support to attend the International Symposium. Dr. O... Read more about AVS Graduate Research Award for Chris O'Connor

JACS features IMASC work on cover

October 5, 2020
IMASC researchers have demonstrated a method to map complex surface dynamics at atomic resolution on a timescale that would have been unthinkable before. The paper, which is featured on the cover of the Journal of the American Chemical Society, describes a method to simulate atomic movements on the surface of catalysts quickly and accurately, a critical step towards engineering better and more...
