Claims

C1strongest claim

NPs with a surface area-to-volume ratio above about 1.8 nm^{-1}, or with a linear size under 3-6 nm, behave differently from larger particles. For these smaller NPs, scaling of their total surface area and volume with the linear size can deviate from quadratic and cubic dependencies, respectively. Their mean interfacial separation and relative contact area change rapidly with size.

C2weakest assumption

The molecular dynamics model and the procedure mimicking thermal dewetting of thin films accurately capture the physisorption interactions and morphological evolution of real Al and Cu nanoparticles on suspended graphene without significant artifacts from potentials or finite-size effects.

C3one line summary

Small Al and Cu nanoparticles on graphene show deviations from quadratic and cubic scaling in surface and volume, rapid changes in contact properties, and irregular height distributions below 3-6 nm, while larger ones exhibit Gaussian fits and self-affine roughness.
