In addition to its exotic electronic properties graphene exhibits unusually high intrinsic thermal conductivity. The physics of phonons--the main heat carriers in graphene--has been shown to be substantially different in two-dimensional (2D) crystals, such as graphene, from in three-dimensional (3D) graphite. Here, we report our experimental study of the(More)
Descriptors and quantitative structure property relationships (QSPR) were investigated for mechanical property prediction of carbon nanotubes (CNTs). 78 molecular dynamics (MD) simulations were carried out, and 20 descriptors were calculated to build quantitative structure property relationships (QSPRs) for Young's modulus and Poisson's ratio in two(More)
The interfacial properties for a carbon nanotube on a Ni (001) surface are modeled by a piece of vertical graphene standing on a Ni (001) surface. The interaction between the graphene and the nickel (001) surface is investigated using density functional theory (DFT) calculations. Zigzag type graphene can stand on the hollow sites of the Ni (001) surface(More)
