Strained lattice with persistent atomic-order

PhD student Sagar Prabhudev along with Matthieu Bugnet (Post-doc) and Dr. Botton published an article in the trending materials journal ACS Nano, introducing the newest nanocatalyst member to Pt-Fe system with an intermetallic core-shell (IMCS) nanoarchitecture. These catalysts were found to exhibit the highest activity and catalytic durability compared to all other Pt-Fe systems reported thus far. Their work that was carried out in collaboration with Dr. Christina Bock at NRC-Ottawa was featured under Nanowerk’s Spotlight, available to here
