Multiscale morphology and contact mechanics of physisorbed Al and Cu nanoparticles

Key Points

• This research examines how the size of aluminum and copper nanoparticles affects their shape and how they interact when placed on graphene.
• Conducted large-scale molecular dynamics simulations to analyze nanoparticle properties.
• Investigated both morphological and contact mechanics properties of coated nanoparticles.
• Studied the scaling behavior of nanoparticles in relation to their size.
• Physisorption affects the morphology of nanoparticles, leading to distinct scaling properties.
• Contact mechanics properties reveal significant size-dependence for both aluminum and copper nanoparticles on graphene.
