There are two cases in particle deposition studies that should be mentioned in this regard; (i) favourable deposition where the combined van der Waals and EDL interactions between the particle and wall are attractive, (ii) unfavourable deposition where a repulsive energy barrier exists in the interaction energy profile.
The explanation of the critical state was only the first step taken by van der Waals to develop a molecular theory of liquids.
These values provide an estimate of the axial bond strength, since in the elongated structures the Cu-axial ligand distances are all higher than the sum of van der Waals radii.
The TE model introduces the dimensionless numbers which consider the van der Waals forces of attraction in the interaction with particle thermal energy--the van der Waals Number (NvdW)--and the relation between the van der Waals forces of attraction and the fluid velocity in the interception of particle collision--Attraction Number ([N.
2] dispersion that takes into account three major components to the interaction between colloidal particles, namely van der Waals attraction, repulsion between polymer coating layers, and a hard-core particle repulsion.
Ionic liquids are salts with melting points below 100 degrees Celsius, and represent a new class of non-molecular liquid materials with unique property profiles due to a complex interplay of Coulombic, hydrogen bonding, and van der Waals interactions.
75*V)[pi])1/3 where D is the minimum molecular diameter and V is the van der Waals volume of the molecule, and the minimum molecular diameter is greater than the size of the pores having antimicrobial metal ions disposed therein, wherein (b) and (c) are present in amounts such that the composition, when applied onto a substrate and cured, provides a cured coating that exhibits UV color stability comparable to the UV color stability exhibited by the same composition that does not include (b) and (c), and wherein the halogen counterion-containing onium compound is a monomeric quaternary ammonium salt having the formula: R4N+X-, where each R is a hydrocarbon and each may be the same or different and X is a halogen atom.
16) considered the contribution of the short-range van der Waals interaction and the long-range electrostatic force and used the energy minimization method to analyze the confinement-induced interface instability between dissimilar elastic thin films.
6) Dynamic pull-in instability of electrostatically actuated beams incorporating Casimir and van der Waals forces
Gecko toepads adhere through a combination of weak intermolecular forces, called van der Waals forces, and frictional adhesion.
