1 Dispersion Forces Van der Waals or London dispersion forces are the universal forces responsible for attractive interactions between nonpolar molecules. The occurrence of these short-range interactions is due to the fact that any atom will, at any given instant, be likely to possess a fini...
In the case of neon atoms, dispersion forces are present due to the fluctuations in electron distribution around the atom. Even though neon is a noble... Learn more about this topic: Atoms vs. Molecule | Definition, Differences & Characteristics ...

The presence of dispersion forces, i.e., Casimir and van der Waals attractions, are included in the theoretical model considering the correction due to the presence of liquid media between the interacting surfaces (three-layer model). To this end, a kind of microplate has been designed, i.e...
Dispersion forces are not included in conventional density functional theory (DFT), which poses a challenge to the theoretical description of the interfacial properties of these molecules on solid surfaces. However, the inclusion of dispersion forces has been realized in recent developments of DFT9–...
London dispersion forces don't require a polar dipole molecule to be present and act in all materials, but they are usually exceedingly weak. The force is stronger for larger and heavier atoms with many electrons than for small atoms, and it can contribute to the physical characteristics of th...
The findings of the study indicated an improvement in the mechanical properties and wear resistance of the composites, especially in the outer region, with an increase in the weight fraction of particles owing to the influence of centrifugal forces. In the study conducted by19, the distribution ...

Moreover, as discussed in Chapter 10, four-wave mixing occurring when GVD is relatively low forces one to operate WDM systems away from the zero-dispersion wavelength. Of course, GVD-induced pulse broadening then becomes of serious concern. The technique of dispersion management provides a ...
