The van der Waals coefficients between carbon nanostructures and small molecules: A time-dependent density functional theory study
We employ all-electron ab initio time-dependent density functional theory based method to calculate the long-range dipole-dipole dispersion coefficient, namely, the van der Waals (vdW) coefficient (C6...

Size-selected Ptn (n=4,7–10,15) clusters were deposited on TiO2(110)−(1×1) surfaces and imaged at atomic resolution using an ultrahigh-vacuum scanning tunneling microscope with a carbon nanotube tip. Clusters smaller than Pt7 lay flat on the surface with a planar structure and a planar-to-three-dimensional transition occurred at n=8 for Ptn clusters on TiO2. However, both Pt8 and Pt9 had two types of geometric structures. The geometric structures depend strongly on the number of atoms in the deposited cluster possibly because of the differences in binding energies in different-sized clusters and different degrees of interaction with the surface. We obtained atomic-resolution images of size-selected clusters on surfaces for the first time, enabling the identification of atomic alignments in the clusters on the surface. ©2009 American Institute of Physics
