van der Waals force (redirected fromVan der Waals interactions) Medical Encyclopedia van der Waals force n. A weak, short-range attractive force between atoms or molecules caused by their dipole moments, often arising in otherwise nonpolar atoms or molecules from a temporary shift of orbital electr...
van der waals interactionsVan der Waals interactions are universally present interactions which always appear when two molecules come close to each other. They are considered as weak attractive interactions which become appreciable only when the interacting molecules are neutral and non-polar. Van der ...

van der Waals heterostructures—allows the fabrication of high-quality GQDs for transport experiments. The in-plane heterostructures allow fabrication of GQDs without the dangling bonds and localised states at the perimeter. At the same time, the van der Waals heterostructures allow fabrication of ...

When reading the literature, it is important to bear in mind which forces are being referred to by the term van der Waals forces. Some authors include all three of the types of dipole interactions mentioned here as van der Waals forces, whilst other authors specifically only mean the ...
van der Waals interactions between atoms and dielectric surfaces are reinvestigated. To describe the nonretarded interaction potential between a dispersive dielectric surface and an atom in an arbitrary internal energy state, we derive a general expression in terms of an integral, over real frequency,...

We formulate and evaluate the van der Waals part of the free energy due to a dielectric profile that varies continuously throughout the space between two interacting bodies. Not considering the work needed to create the inhomogeneous dielectric profile, focusing only on that part of the free energ...
