Flake graphite has been found to transform into spherical graphite in liquid nickel. Graphite spheres with diameters ranging from 300 to 1μm have been extracted by acid erosion of the nickel, and have been characterized using various techniques. The surface of graphite spheres shows disordered atomic stacking and defects. This is in agreement with the Raman spectrum result which shows that the structure...
Molecular dynamics simulation is used to study the transport behavior of water molecules along an open-ended single-walled carbon nanotube (SWCNT) under the driving force of methane molecules. The methane molecules pull the water molecules from the inside of a SWCNT along the axial direction. The transport velocity of water molecules increases with increasing number of methane molecules, but decreases...
