Impact Induced Desorption of Large Molecular Structures from Graphitic Substrates

Webb R.P., Kirkby K.J., Advanced Technology Institute, UK

We use molecular dynamics computer simulation to show how the impact of a C60 molecule on a garphite surface can cause an acoustic wave across the surface of the substrate which is strong enough to [...]

Wetting and Hydrophobicity of Nanoscale Systems with Impurities

Gonnet P., Zimmerli U., Walther J.H., Werder T., Koumoutsakos P., ETH Zürich, CH

Molecular dynamics simulations are performed to study the influence of surface and fluid impurities on water-carbon interfaces. In order to quantify these interactions we consider both the canonical problem of wetting of a doped flat [...]

Water-Carbon Interactions: Potential Energy Calibration Using Experimental Data

Werder T., Walther J.H., Jaffe R.l., Koumoutsakos P., NASA Ames Research Center, US

Functionalized carbon nanotubes (CNT) are being studied for use as nanoscale biosensors and water or proton channels. Several molecular dynamics (MD) studies of water in carbon nanotubes have recently been performed to gain further insight [...]

Increase the Synthesis Efficiency of Graphite Encapsulated Cobalt Nanoparticles by Annealing

Teng M.H., Lin C.C., National Taiwan University, TW

Graphite/carbon encapsulated metal (GEM) nanoparticles (Fig.1) not only provides an opportunity to study dimensionally confined systems, but also could be used in many nanotechnology applications, e.g. recording media, nano-sized wheel bearings, etc. Unlike other metal [...]
