Recent Findings from School of Chemical and Biomolecular Engineering Provides New Insights into Surface Science [Adsorption and diffusion of Rh and Au dimers and trimers on graphene/Ru(0001)]

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Science. According to news reporting originating from Atlanta, Georgia, by NewsRx correspondents, research stated, "Periodic density functional theory (DFT) calculations have been performed to study metal nanoparticles on graphene/Ru(0001). Specifically, we examined adsorption and diffusion of monomers, dimers, and trimers of Rh and Au on graphene/Ru(0001)."

Our news editors obtained a quote from the research from the School of Chemical and Biomolecular Engineering, "These two metal species were chosen for their distinct behaviors in cluster formation on the graphene/Ru(0001) moire. The fcc region of this surface was predicted to be where the nucleation of metal nanoclusters occurs. The diffusion mechanisms and energy barriers for metal dimers and trimers were calculated. It was shown that the mobility of Rh clusters decreases with the increase of cluster size. For Au, however, dimers and trimers diffuse faster than monomers on the moire surface."

According to the news editors, the research concluded: "These calculations give insights into the nucleation process of metal clusters on the graphene moire."
