..., it is a stack of graphene sheets of carbon atoms covalently bonded within a basal plane but weakly bonded by Van der Waals forces between the planes ( 1 ). Thus, it displays itself at the nanometer scale as a stack of plates buffered by a relatively “soft” material. The plates represent the graphene sheets...

... by taking the MWCNT as a whole beam, the current shell model can find the resonant frequencies of three modes being classified as radial, axial, and circumferential for each nanotube of a MWCNT. Big influences from the small length scales and the van der Waals’ forces are observed. Among these, noteworthy...

... the thermal buckling behavior of multi-walled carbon nanotubes. The multi-walled carbon nanotubes are considered as concentric thin shells coupled with the van der Waals forces between adjacent nanotubes. Closed form solutions are formulated for two types of thermal buckling of a double-walled carbon nanotube...

... into contact with the elastic half-plane, van der Waals forces come into play if the gap width between the two surfaces is, say, below 100 nm, 1 3 . For instance, a simple general expression for the van der Waals attraction between two flat surfaces, as function of the distance, can be found in 3 . Thus...

...C. Q. Ru This paper studies surface instability of a compliant elastic thin film on a rigid substrate interacting with a suspended elastic plate through van der Waals forces. The analysis is based on a novel method which permits a simple rational expression for the interaction coefficient...
