Ortega. Weak chemical interaction and van der waals forces between graphene layers: A combined density functional and intermolecular perturbation theory approach. Phys. Rev. B, 74:205434, Nov 2006.Dappe, Y.; Basanta, M.A.; Flores, F.; Ortega, J. Weak chemical interaction and van der ...
From the above discussion, we can conclude that there is covalent bonding between the carbon atoms in both the graphite as well as diamond but it is the weaker Van der Waals forces acting between the layers in graphite which make it soft whereas no such layers or w...
Van der Waals radius is the radius of an imaginary sphere surrounding an atom. It represents the distance of the closest approach for another atom. In other words, van der Waals radius is one half of the distance of separation between the center of the two approaching nuclei. It is a para...

Due to the combination of entropic factors and interactions between the liquid molecules and the surface itself [1], high-density structured layers of molecules are formed, originating oscillatory solvation forces. They play a fundamental role in colloidal and interface phenomena such as friction and ...
The coefficient of friction\((\mu )\)can be divided into two different phenomena, the static and the kinetic friction which corresponds to the resistance to movement in two different phases [15,16]. The first corresponds to the frictional force needed to initiate the movement between two surfac...
I found an exercise in which I had to attribute "covalent", "Van Der Waals" and "ionic" to the compounds. I was given "diamond", "naphthalene", and "magnesium oxide". The answer is that diamond is covalent, naphthalene is Van Der Waals, and magnesium oxide is ionic. ...

For these simulations, nano-sized graphite was compressed and slid on a SiOcoated Cu substrate at different thicknesses of the SiOlayer. The study showed that the critical compressive strain for exfoliation decreases as the coating thickness decreases, achieving multiple layers of exfoliation. The ...
